Hi,

I want to use a dll in my UWP app. I have created a bridge (followed the example AppServiceBridgeSample). It contains a BackgroundProcess which is c# console application. UWP uses the bridge to communicate with console application.
Issue:

1. If I reference a dll in BackgroundProcess , I get the error "System.IO.FileException, Could not load assembly or File", when I am running the UWP app.
   Please let me know what is the right way to add a dll in BackgroundProcess so that we can use it the UWP app.
   PS: The Background process with the dll works fine when run as standlone application. But when communicating via the Bridge, the above exception is thrown ( "System.IO.FileException, Could not load assembly or File") .

Hi there,

the SystrayExtension-Sample does not seem to work. When deploying the solution and executing it, it successfully launches the WinForms tray icon application. However, when e.g. double clicking the tray icon to open the UWP application, it crashes with an exception:

System.InvalidOperationException: 'The process has no package identity. (Exception from HRESULT: 0x80073D54)'

Can you give me a hint on how to fix this? Haven't found anything useful yet.

In the AppServiceBridge sample, the win32 app, if shut down, will cause the UWP app to shut down. That isn't desired. How can this dependency be avoided?

1. Start UWP app
2. Start Win32 process
3. Win32 process connects to UWP app
4. Close Win32 process
5. UWP shuts down a few seconds later without suspending. (How can we avoid this)

Thanks,
Michael

Using the appx generated from PhotoStoreDemo.Pakcage project, when click on "Add Photo" button, the file dialog first shows up and then a second windows show up and states this program has stopped working... It works if it is ran under PhotoStoreDemo.Package.Debug (the project also misses the package layout file)

What does it mean? Where should I put the backgroundprocess.exe?

I see a lot of example wrote by c#
can you make an example call from UWP from C++

Trying to follow guide here (Migrate step) and using this sample, I'm getting following error when uploading to the Store

Package acceptance validation error: Apps converted with the Desktop Bridge and that require the .NET Native framework must be pre-compiled by the .NET Native tool chain.

Is there a way to upload to Store?

Are there any known issues with unplated / *_altform-unplated.png icons (or in general scaled resources) for Windows Bridge apps?

Scaled (e.g. *.scale-100.png) resources seem to get fully ignored for my Desktop Bridge app even though it works fine UWP apps.

I built step 4 and ran it once. After closing the app, I'm now getting toast notifications every 10-20 minutes telling me my status is "available." I've killed every running process Windows would allow me to, and rebooted, and it continues. What is the DLL, service, or process that is causing this, so I can shut it down?

ETA: Nothing Windows restore couldn't fix.

I get the: "update AppxManifest.xml". I published the app to windows store, so app identity can't be wrong. ( the manifest is checked by that process ). Also I have 2 add-ons "Consumable (Store-managed)" in this app.
Also I added using Windows.ApplicationModel and checked if all the data from the manifest is correct.

PS: after "StoreContext storeContext = StoreContext.GetDefault();" storeContext is still null.

On build 17713, the AppServiceBridge console app systematically fails to connect to the UWP app, the status output by connection.OpenAsync() always being "Unknown".

Compiling UWPWrappers of VB6withXaml project an Error C1107 occurs.

Below the complete error message
"could not find assembly 'platform.winmd': please specify the assembly search path using /AI or by setting the LIBPATH environment variable "

First I try the code as following:
var connection = new AppServiceConnection();
connection.AppServiceName = "RegistrationService";
connection.PackageFamilyName = TargetPackageFamilyName;
var connectionStatus = await connection.OpenAsync();
But I got the error status "AppNotInstalled".

I replace TargetPackageFamilyName to another UWP App's PackageFamilyName, and run "connection.OpenAsync()" again. I can get the correct status "Success".

And I replace the code as following:
Launcher.QueryUriSupportAsync(uri, LaunchQuerySupportType.Uri, TargetPackageFamilyName)
I can get the status "Available" and launched success.

Occurrence of the current computer environment is Windows 10 15063.250.

I try to uninstall the target UWP App, and run "connection.OpenAsync()" again. I got the error status "AppServiceUnavailable" and found that target UWP App didn't completely be removed in "C:\Program Files\WindowsApps".
Try to update Windows OS to 15063.674, and reinstall the target UWP App, the problem still exist.
Please help me to resolve the issue. Thanks.

Where can I get Windows 10 SDK 10.0.14342.0?

Unless Im missing something, Insider Preview page still only has a link for

Windows 10 SDK 10.0.14332.0

Wont let me build without it.

Thx!

In AppServiceBridgeSample , Package.appxmanifest showing an error at <desktop:Extension Category="windows.fullTrustProcess" Executable="BackgroundProcess.exe" /> and <rescap:Capability Name="runFullTrust" />.
Please help to resolve the issue.

In the WinformAppService example, the README.MD mentioned that:

"This component gets activated out-of-proc to the main application process, so we also need to declare a package-level extension to explain to the system how the class will get activated."

But I can't find more detail about the package level extension.

Also notice that the vcxproj file missing the Package.StoreAssociation.xml, is that related?

Hello!
In AppServiceBridgeSample BackgroundProcess sends a message (response) to UWP, if a corresponding request is received... I have modified this sample. So BackgroundProcess communicates with another process (win32host), using pipes. So there is a thread, which BackgroundProcess uses to read messages from win32host, convert received data to ValueSet and redirect it to UWP using SendMessageAsync method of connection object. Also I have added corresponding RequestReceived handler to connection of UWP programm. It works fine, but I have a question about connection object of BackgroundProcess. Is it thread safe? I mean, is it normal that this object can be used by two threads at the same time? I assume, that the first thread uses it on Connection_RequestReceived, and the second thread (which reads responses from win32host) uses SendMessageAsync method of this object. Could you explain me this moment? And in which thread event handlers of connection object are executed? May be I missed something in the documentation...

I am implementing ThumbnailHandler in C ++ and try to distribute desktop applications with APPX.
However, although the application association works fine, ThumbnailHandler did not work.
I would like to make APPX with thumbnail handlers like 'Paint.Net' (on Microsoft Store).

I would like a sample of a thumbnail handler for dummy extension.
Thank you for your consideration.

Nice article on the Systray extension with UWP!

I found that with the Microsoft.Windows.SDK.Contracts nuget packages you do not need to reference the winmd files anymore, which makes your code cleaner.

Please refer to https://docs.microsoft.com/en-us/windows/apps/desktop/modernize/desktop-to-uwp-enhance.

Building and deploying works. When I click on "Launch Background Process" I get a message box (see attachement)

I am the administrator of my machine. Is there anything I have to set/change, so the uwp can launch the background process?

Hello,
I run this app: https://www.microsoft.com/vi-vn/p/vb6-app-with-xaml-sample/9n191ncxf2f6?rtc=1&activetab=pivot:overviewtab
to generate toast notification. Then I click on the notification, but it launches a new instance of the app instead of resuming from then existing app.
Could you please let me know why it happened? and how to fix this?
I want to integrate push notification into my Desktop bridge app and have the same problem.

Thank in advise!

No code change, just clone and build. Hit Build errors when trying to compile JourneyAcrossTheBridge_Build2017Edition\Step2

Hello,

I am interested into: https://docs.microsoft.com/en-us/windows/uwp/monetize/configure-your-app-to-receive-dev-center-notifications, but to do that I would need the Microsoft Engagement Framework as reference inside my bridged uwp app.
Until now I couldn't add it. Is there any special step that an bridge app must do in order to get it done?

All the best,
Stefan

Hi, thanks for the samples. I have a reference problem in the UWP Systray sample
In SysSystrayComponent project

Cannot be found in SystrayApplicationContext class.
Thanks

I have a working Brokered Component along the lines of the MSFT article here. I have also read Adam Braden's recent post "Calling WinRT Components from a Win32 process via the Desktop Bridge" here, which references the WinformsOutOfProcessWinRTComponent sample.

I have built the sample but get an error: "The application appears to already be running" when trying to launch for debug. This is with VS 2017 15.4.0 Preview 1.0 and SDK 16210. I have tried killing the COM Surrogate, and even rebooting, to no avail.

The sample isn't quite my use case however, and uses a hand-rolled COM DLL. I am ultimately looking for is some sample or walk-though that consists of:

• A UWP C# application containing the UX inside the app container
• A WRT C++/CX component containing some non-UX application logic that runs outside the app container "full trust"

A WRT component running outside the sandbox that returned "hello" from a method would do.

The app won't be in the store, because the WRT component requires verboten win32 calls. How might I achieve this? The article mentions "metadata marshalling" but it is commented out in the appxmanifest here. I think the pieces are there, but I am having trouble putting them together. Any help appreciated.

I see that Directory.Exists(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) + "\PreviousPhotoStore") == false. If you haven't created the "PreviousPhotoStore" folder, how can you migrate the user data?

Hi,

I have a working app in the store called Glancer: https://www.microsoft.com/en-us/store/p/glancer-pc-vitals-at-a-glance/9nblggh43gvm

Im working on an update that ads some functionality as a jumplist:

It all works but once I have converted it, using the desktop app converter the jumplist no longer works. No error or anything, it just doesnt show:

Any idea why that might be?

1. I downloaded https://developer.microsoft.com/en-us/windows/downloads/virtual-machines for VirtualBox. Unpack, import and run the VM.
2. Run VS Installer and update to the latest version: 15.7.4
3. Install TortoiseGit + Git and clone this repository
4. Launch VS 2017, log in with my MSDN/VS account.
5. Open the AppServiceBridgeSample (C#) solution and, for UWP, VS update is required, so I target the latest UWP SDK: v1803 (10.0; Build 17134).
6. If I look at the BackgroundProcess's References, the Windows has warning icon.
7. When I build it [Config: DEBUG; CPU: Any], then it reports 5 errors:

On my desktop, I have VS 2017 Pro, and I'm able to clone and build with no error.

8. I tried to reference C:\Program Files (x86)\Windows Kits\10\UnionMetadata\Facade\Windows.WinMD
   which reduced the errors down to 3:

9.When I copy over the folder [which built OK] from my desktop to VM, then it builds OK, too.

[10. I made changes to this solution and when I check in and out from repository, I get the same build problems on VM but not my desktop.]

So, my questions are: is this problem specific to VS2017 Community edition or just VM issue [only on VirtualBox?]? Or is there some setup/config needed that's missing in the VM environment?

Tried loading this solution with the Windows 10 AU SDK and got errors about missing components (from a different build SDK I don't have installed). After manually editing the UWP csproj file to change the version numbers to the AU release number (14393) it was able to load, however the background app fails with:

An exception of type 'System.InvalidOperationException' occurred in BackgroundProcess.exe but was not handled in user code

Additional information: The process has no package identity. (Exception from HRESULT: 0x80073D54)

This occurs on the following line:
connection.PackageFamilyName = Windows.ApplicationModel.Package.Current.Id.FamilyName;

Scratch that, the second part came from the fact that when the UWP project didn't load initially VS set the background app as the startup project so when I hit F5 it tried to run as a normal Win32 app instead of launching the UWP app which would then start the background app. So there's only one issue here and that's the build numbers in the UWP.csproj file need to be updated to the final RTM.

I generated the UWP application package through the MSIX Packaging Tool or the Desktop APP Converter. After installing this package, we cannot find this application from the Kiosk App list during the process of setting the Kiosk mode.
Converted UWP application how to support kiosk mode?

Creating a store app and installing it will succeed but on launch Windows won't find vclibs.

Please update the Sample to reference the dependency in the manifest.

Compiling the code in release mode works, also debug mode works fine all the way.

Has anyone a solution for this?

I have:

• An UWP App
• A Console App (.NET Framework)
• A Package project

This is (part of) the package.appxmanifest that tells you how it is setup:

  <Dependencies>
    <TargetDeviceFamily Name="Windows.Universal" MinVersion="10.0.0.0" MaxVersionTested="10.0.0.0" />
    <TargetDeviceFamily Name="Windows.Desktop" MinVersion="10.0.14393.0" MaxVersionTested="10.0.14393.0" />
  </Dependencies>

  <Resources>
    <Resource Language="x-generate"/>
  </Resources>

  <Applications>
    <Application Id="App"
      Executable="$targetnametoken$.exe"
      EntryPoint="$targetentrypoint$">
      <uap:VisualElements
        DisplayName="CularBytes W10 App"
        Description="Package"
          .... />
      </uap:VisualElements>
      <Extensions>
        <uap:Extension Category="windows.appService">
          <uap:AppService Name="SampleInteropService" />
        </uap:Extension>
        <desktop:Extension Category="windows.fullTrustProcess" Executable="CularBytes.App.WindowsApp.Bridge\CularBytes.App.WindowsApp.Bridge.exe"/>
      </Extensions>
    </Application>
  </Applications>

  <Capabilities>
    <Capability Name="internetClient" />
    <rescap:Capability Name="runFullTrust" />
    <rescap:Capability Name="allowElevation" />
  </Capabilities>

As you can see I want to run it in the same process.

The Console app contains an app.manifest, so that I can define elevated permissions needed:

<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

Within the Console app I start the AppService connection:

        private static async void InitializeAppServiceConnection()
        {
            AppServiceConnection Connection = new AppServiceConnection();
            Connection.AppServiceName = "SampleInteropService";
            Connection.PackageFamilyName = Package.Current.Id.FamilyName;
            Connection.RequestReceived += Connection_RequestReceived;
            Connection.ServiceClosed += Connection_ServiceClosed;

            AppServiceConnectionStatus status = await Connection.OpenAsync();
            if (status != AppServiceConnectionStatus.Success)
            {
                // something went wrong ...
                Console.WriteLine("status not success on connecting, status:" + status + " pacakgeName:" + Connection.PackageFamilyName);

            }
            else
            {
                Console.WriteLine("Status success!");
            }
        }

Somewhere from the UWP app, I start the FullTrustProcess like documented:

        if (ApiInformation.IsApiContractPresent("Windows.ApplicationModel.FullTrustAppContract", 1, 0))
        {
            await FullTrustProcessLauncher.LaunchFullTrustProcessForCurrentAppAsync();
        }

The console app starts like expected but the connection is not successful, console.writeline prints:

status not success on connecting, status:Unknown pacakgeName:df84c6a8....

I verified that the packageName is correct.

When I remove <rescap:Capability Name="allowElevation" /> from Package.appxmanifest and <requestedExecutionLevel level="requireAdministrator" uiAccess="false" /> from app.manifest, then the connection is successful!

So why, due elevated client-app, is the connection not working?

I need elevated permissions to do more actions from the console app. Don't bother asking what that is, I know I will have Microsoft Store limitations, etc. Please help me solve this issue.

Do I need to use another packageName? Is that changed when using allowElevation? How can I find this out?

But, when i call AppService on winform or wpf client, the AppServiceConnectionStatus still return AppServiceUnavailable.

How can I solve this issue?

My sample project https://setup.aserweb.com/AppServiceSample.zip

Thanks a lot.

Hi team !

I have an error, when trying to run the ``HelloWorldConsoleSample` application

The error occurs on runtime on the TileUpdateManager.CreateTileUpdaterForApplication() method
The exception is :

System.Exception: 'Element not found. (Exception from HRESULT: 0x80070490)'

Actually, I have the last VS 2017 (version 15.2 (26430.6)) installed.
I have installed the last Windows 10 SDK as well.

And I have no InnerException ...

set up a single-app kiosk for PhotoStoreDemo App.
When the user logs in, Windows attempts to run the application (the blue window appears with the loading spinner). The whole screen flickers for a minute or so and then an error message appears stating:

"We weren't able to start your app. Press Ctrl + Alt + Del to sign out or contact your system admin. For more info, search online for error code: 0x80270254".

Hi,

Thank you for your sample code , is there any code/knowledge on how to do DesktopBridge on javascript version? My code is on hosted web app and want to call Desktop App to get data.

Right now what I do is set appService to be StartPage="js/appservice.js"
and after UWP ( index.html ) call to Desktop via launchFullTrustProcessForCurrentAppAsync it open WPF App , after that WPF app call back on AppServiceConnection and open the connection to UWP App on StartPage ( appservice.js ) but my deadend here since my index.html cannot get anything from appservice.js , even in appservice.js show messagebox that come from WPF it still not show.
Did I missing some concept or how I can make it work

Thank you,
Tour
