SimpleStubs fails in VS 2019 v16.7.5

[labarilem-nitro]

Hi,

I'm trying to use SimpleStubs in a UI test project for UWP but I get the following error:

3>  SimpleStubs: Generating stubs for project: <...>
3>  SimpleStubs: Failed to generate stubs: System.AggregateException: One or more errors occurred. ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime.CompilerServices.Unsafe, Version=4.0.4.1, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

Is there a way to fix the issue?

Hello @labarilem-nitro, thank you for reporting this. I currently don't have a lot of time to keep updating SimpleStubs but I encourage users to contribute by submitting PRs. SimpleStubs code is like any other C# code and any C# dev should be able to read it and debug it. Please take a look at the Developer Documentation to get started. I suspect this issue may be a simple matter of updating Roslyn packages to latest. If you can give that a try and run the tests as described in the docs, I'd be happy to merge that in a publish a new NuGet.

I have started PR #65 to update the dependencies in hopes that it will fix this issue. If you have any other suggestions for how to test it or proceed, I'd appreciate your help!

Hello @timpalpant, thanks for the PR! To test this further you can update the SimpleStubs.nuspec and generate a NuGet using NuGetPack.bat. Then you can install the NuGet locally and test it in your IDE to see if it fixes the problem.

Note that NuGets often get cached by the framework when installed so I would recommend changing the version every time you generate a new NuGet. I usually add a letter suffix for testing (e.g. 2.4.8.3-a, 2.4.8.3-b) and then remove it once I have a working version.

I hope that helps.
