.NET Standard Support? about dotnetcoreplugins HOT 5 CLOSED

Sorry -- can't do this one. The most important part of this project depends on an API System.Runtime.Loader.AssemblyLoadContext which is not supported in .NET Standard or .NET Framework. So, this project is intentionally only for .NET Core.

Sorry, I don't want to bother, I want to just point out that System.Runtime.Loader.AssemblyLoadContext is available in a nuget package System.Runtime.Loader.
Just for test I've added that package:
<PackageReference Include="System.Runtime.Loader" Version="4.3.0" />
and target netstandard:
<TargetFramework>netstandard2.0</TargetFramework>
Rebuilding all without errors, tests also succed.

Now I suppose that this won't work if this library is linked to a full .net project but at least in the above scenario I describe why not?

It's a good question. You've found one of the more obscure mistakes in .NET Standard 1.x packaging. Checkout this thread https://github.com/dotnet/corefx/issues/22142#issuecomment-444583754. Even though things look okay to the C# compiler, when you run a .NET Framework app, it will always fail with an error like this: FileNotFoundException: Could not load file or assembly 'System.Runtime.Loader'.

Understand, I guess that under the full .NET framework one should use the classical Assembly.LoadFrom from Reflection API or just give up with a PlatformNotSupported exception (at least until .NET framework team fixes the issue).
I think is important to move this wonderful library to NET standard with its wider audience: if it's fine for you I can just pull a request.

There is no equivalent API on .NET Framework, and I don't see any value in targeting .NET Standard. This project is intentionally designed for .NET Core only. Unless the .NET Framework team adds the AssemblyLoadContext feature (which is extremely unlikely), I'm not going to change the framework support on this library.

Just to be clear - you can still write plugins using .NET Standard. But the host which loads plugins must be written in .NET Core.
