Hi,
just wanted to make you aware that the Middleware setup fails with the following exception when using FakeItEasy 7.

System.EntryPointNotFoundException
Entry point was not found.
   at FakeItEasy.Configuration.ICallbackConfiguration`1.Invokes(Action`1 action)
   at FakeItEasy.CallbackConfigurationExtensions.Invokes[TInterface,T1](ICallbackConfiguration`1 configuration, Action`1 actionToInvoke) in C:\projects\fakeiteasy\src\FakeItEasy\CallbackConfigurationExtensions.StronglyTyped.cs:line 31

In the dependencies of your package the range is listed as FakeItEasy ≥ 6.0.0 which basically allows FakeItEasy 7. Maybe you should update this range to prevent people from having the same troubles as myself.

Let me know if you need any more details. Thanks in advance!

When deleting a record all associated entity references (lookups) pointing to that record should be set to null.

Ideally also implement this logic based on cascade rules.

Hello @jordimontana82 ,
I have been "struggling" a little with building all the packages, and I think I found the issue 😄 basically the powershell scripts need to have "all" as a default value for $targetFrameworks so that it produces all the packages with all the necessary frameworks when building it locally.

I'm trying to build the project(s) using the instructions in Readme.md.
I have cloned all of the 2x-dev repos to a folder structure like this:

I have all of the prerequisites installed.
When I run any of the build scripts (eg ./build.ps1 -targetFrameworks all) I get a slew of errors, but the first is this:
C:\Program Files\dotnet\sdk\6.0.101\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets(267,5): error NETSDK1005: Assets file 'C:\DynamicsValue\fake-xrm-easy\src\FakeXrmEasy\obj\project.assets.json' doesn't have a target for 'net452'. Ensure that restore has run and that you have included 'net452' in the TargetFrameworks for your project. [C:\DynamicsValue\fake-xrm-easy\src\FakeXrmEasy\FakeXrmEasy.csproj]

Not sure if I'm doing something wrong?

When you build a fetchXml query using the toolbox fetchXml builder which uses the in or not-in operator, it leaves a little bit of redundant fluff in the query:

When you run an early bound query with a condition like this, CRM does not complain and just ignores the value='' bit.
When you run it in fake-xrm-easy (v9 v2 and v3) you get this exception:
System.Exception: When trying to parse value for entity van_technician and attribute statuscode: Integer value expected

I know it's a simple one to avoid, but I think it's worth raising because it took me quite a while to work out that the problem wasn't with the real integer values in the value tag, but the unnecessary value='' attribute in the condition node, so this might trip other people up as well. I couldn't see what was wrong with the query because I was looking in the wrong place, but anyway, it's a valid query as far as CRM is concerned!
I'll also raise an issue in the FXB repo.

It would be great if the library would support working with the interface IOrganizationServiceAsync (https://github.com/microsoft/PowerPlatform-DataverseServiceClient/blob/ba545dcbec78d82dc1aa180b40eaee939978761e/src/GeneralTools/DataverseClient/Client/Interfaces/IOrganizationServiceAsync.cs). Do you have anу plans for it?

This will allow to debug locally the code of plugins but using a connection to a real target environment.

• Add functionality to the plugins package
• Add similar functionality to the code activities package

When querying a Money attribute, this query is valid against a real CRM instance:

Against FXE (v2/v9) it gives this error:
The binary operator Equal is not defined for the types 'System.Decimal' and 'System.Int32'.

Easy to fix in code by changing to
query.Criteria.AddCondition("priceperunit", ConditionOperator.Equal, 1.0m);
but just pointing out difference between 'real' behaviour and FXE behaviour.
Sorry if its already reported.

More info:

https://docs.microsoft.com/en-us/power-apps/developer/data-platform/special-update-operation-behavior

i.e.

    new OrganizationRequest()
    {
         RequestName = "Create",
         Parameters = new ParameterCollection
         {
                { "Target", new Entity() }
         }
    }

Should be treated like the current

    new CreateRequest()
    {
         Target = new Entity()
    }

• Create
• Update
• Delete
• Retrieve
• RetrieveMultiple

Queries against MultiSelect OptionSet which use the ContainValues and DoesNotContainValues operators fail with a 'Object reference not set to an instance of an object' exception.

Here are some unit tests, all of which should pass, but do not:
Issue467.zip

If you have a query with a filter which contains conditions affecting both the main query entity and a link entity it fails.
In SQL this would be something like this:

SELECT c.firstname, a.name 
FROM contact c
    , account a
where c.accountid = a.accountid
and (c.firstname like 'A%' or a.name like 'A%')

This can be written in fetchXML like this:

<fetch top='50'>
  <entity name='contact'>
    <attribute name='firstname' />
    <filter type='or'>
      <condition attribute='firstname' operator='begins-with' value='A' />
      <condition entityname='account' attribute='name' operator='begins-with' value='A' />
    </filter>
    <link-entity name='account' from='accountid' to='parentcustomerid' link-type='inner' alias='account'>
      <attribute name='name' />
    </link-entity>
  </entity>
</fetch>

This is a valid query and returns a resultset, as seen here:

Using FakeXrmEasy (v2) gives an 'Object reference not set to an instance of an object.' error.
This is true with either an and or an or filter.

Comment out this line:
<condition entityname='account' attribute='name' operator='begins-with' value='A' />
and the query runs OK, so it seems to be something to do with the aliased link-entity in the filter.

I will upload a failing test once I've submitted the issue.

Scenario is a custom API plugin, and a further plugin registered PostOperation Async on the same message.

I've been able to test the API plugin by setting up a FakeMessageExecutor on the relevant message in which I set up a plugin context and call the plugin. When I run the calling code to send this message, the APIU plugin gets executed correctly.

If I set up Plugin Registration for the postop plugin though, I can still test the main plugin by this method but the later registration is not called.

I think the issue is at https://github.com/DynamicsValue/fake-xrm-easy-plugins/blob/08b7a3f36d9fd10bd941b52224f96bb9f2a6e865/src/FakeXrmEasy.Plugins/IXrmFakedContextPipelineExtensions.cs#L191-L198 where the downstream plugin is only called if target is an Entity or EntityReference.

Even if I were to fakeup a Target in my FakeMessageExecutor, the UsePipelineSimulation code always calls IXrmFakedContextPipelineExtensions.GetTargetForRequest(request), and that method (for obvious reasons I guess) only handles built-in messages.

When I have thought it through a bit more will be happy to offer a PR, if you think this is the right track.

For example, the only possible image to register for Create message is a Post-Image in the Post Operation step...

This has been already implemented when finding out if images are available in pipeline execution but is not implemented when registering images (PreImageTests and PostImageTests).

By throwing exceptions during the registration step we're bringing those issues earlier to the moment when they should be addressed.

I've upgraded Microsoft.PowerPlatform.Dataverse.Client to version 0.6.1 and my unit tests are breaking with the error below.

I honestly haven't spent any time looking into whether the issue is caused by anything my side, so will respond if I find that the issue is not related to the version upgrade.

This might be a duplicate of this old issue from v1: jordimontana82/fake-xrm-easy#584

Testing a query which would be written like this in SQL:

select * from salesOrder s,
salesorderdetail d
where d.quantity is not null
AND
((d.productname = "A" AND d.description = "B")
OR
(d.productname = "C" AND d.productnumber = "D"))

In other words it has a nested sub query against the link-entity, where 2 conditions must both be true OR 2 different conditions must both be true.

Here's how it would look in fetchXMLBuilder and it returns results for both of the OR conditions:

Here's the query:

QueryExpression query = new QueryExpression("salesorder");	
// link to salesorderdetail
LinkEntity query_salesorderdetail = query.AddLink("salesorderdetail", "salesorderid", "salesorderid");

// Quantity not null
query_salesorderdetail.LinkCriteria.AddCondition("quantity", ConditionOperator.NotNull);
	
// Add an 'Or' filter
FilterExpression OrFilter = new FilterExpression();
query_salesorderdetail.LinkCriteria.AddFilter(OrFilter);
OrFilter.FilterOperator = LogicalOperator.Or;
	
// Filter with two Ands - A and B
FilterExpression aAndBFilter = new FilterExpression();
aAndBFilter.AddCondition("productname", ConditionOperator.Equal, "A");
aAndBFilter.AddCondition("description", ConditionOperator.Equal, "B");
	
// Filter with two Ands - C and D
FilterExpression cAndDFilter = new FilterExpression();
cAndDFilter.AddCondition("productname", ConditionOperator.Equal, "C");
cAndDFilter.AddCondition("description", ConditionOperator.Equal, "D");

// Add the two and filters to the Or Filter
OrFilter.AddFilter(aAndBFilter);
OrFilter.AddFilter(cAndDFilter);

EntityCollection installers = service.RetrieveMultiple(query);

and here's my initialisation:

SalesOrder order = new SalesOrder() { Id = Guid.NewGuid() };

SalesOrderDetail detail1 = new SalesOrderDetail() { Id = Guid.NewGuid(), SalesOrderId = order.ToEntityReference()
	, Quantity = 1, ProductName = "A", Description = "B" };
SalesOrderDetail detail2 = new SalesOrderDetail() { Id = Guid.NewGuid(), SalesOrderId = order.ToEntityReference()
	, Quantity = 1, ProductName = "C", Description = "D" };

	_context.Initialize(new Entity[] { order, detail1, detail2 });

The query should return two records, but it returns none.

I can provide a Unit Test, but want to check if this is already a known issue before I do.

The current implementation relies on Dictionary data structures as the internal implementation of entity records and entity metadata records. Such data structure is not thread safe.

Therefore, we need to replace current In-Memory instances of Dictionary by a different implementation like ConcurrentDictionary and rewrite current code accessing the In-Memory state in a way that is also thread-safe.

This is prior work need to support features like #51 #38 among others.

• Mark current Data dictionary as internal and use a new set of InMemory data structures
• Move internal references to EntityMetadata to the new InMemory data structure
• Review other In-Memory data structures that would affect thread-safety (GlobalOptionSets, AccessRightsRepository and other repositories), and moved them accordingly
• Review Clone functionality to be applied at the public interface entry points only for consistency(GetEntityById, CreateEntity, UpdateEntity, DeleteEntity, and possibly CreateQuery methods), and do not use Clone internally for performance, unless necessary.

Using the latest DataverseClient to connect using AuthType works however XrmRealContext fails with the same connection string.

Sample code

var fakedContext = new XrmRealContext("XrmDebug");
var whoAmIRequest = new WhoAmIRequest();

var response = fakedContext.GetOrganizationService().Execute(whoAmIRequest) as WhoAmIResponse;

Using the same connection string with::

var service = new Microsoft.PowerPlatform.Dataverse.Client.ServiceClient(connstring);

Hi @jordimontana82,
a weird cosmetic issue in LINQPad. Don't really know if it's a LINQpad issue or a FXE issue.

With the v1 Nuget packages, it's possible in the LINQPad NuGet package manager to see which version of CRM the package references:

but with the v2/3 packages, it's no longer possible to distinguish them - they all look the same, so it's much harder to chose the right version - you have to select each version in turn in order to be able to see the ID value:

This isn't true in Visual Studio:

Was there some additional info in the NuGet manifest which LINQPad was previously using which is no longer there in v2/3?

Let me know if you need more info or if I can help testing this.

Thanks,
Ben

This is about raising an exception when IfRowVersionMatches property is specified and the RowVersion provided in the request differs from the current one in the In-Memory database.

There is a filter on entityname='mycontact' in unittest ConditionOperatorTests.FetchXml_EntityName_Attribute_Alias_Execution(). If the context is initialized with _context.EnableProxyTypes(Assembly.GetExecutingAssembly());, this test will fail due to the fact that the attribute of the filter is believed to be on the root entity (account) instead of the link-entity (contact).

In order to making the cloning and building of all the different repos and packages a bit more seamless, the build script could be improved to:

• Show a warning if you're not in a DynamicsValue parent folder: to highlight the fact repos should have the same parent folder
• Prompt any warnings if some of the target frameworks or SDKs are missing
• Check if the local-packages folder exist, otherwise create it, via confirm
• Check if a folder for each repo exists, otherwise git clone it, via confirm
• Run git-pull.ps1 on all repos after they've been downloaded
• Build & publish everything into local-packages

• Error when trying to use a message name that doesn't exists: "Invalid Message Name specified, Please re-enter the message name"
• Error when trying to register plugins against specific existing messages as per below:

When we try to regiser a step with the "AssociateEntities" message against a custom plugin, he exception is thrown.

There are probably loads of them (i..e another example is AddAppComponents message against appmodule).
