Could not load file or assembly Microsoft.CodeAnalysis

Hi Cezary,

We are unable to make this work even for a brand new C# console project. We are currently receiving the following error.

 An instance of analyzer CSharpExtensions.Analyzers3.NotNullablePropertyInitializationDiagnosticSuppressor cannot be created from C:\Users\racu\.nuget\packages\smartanalyzers.csharpextensions.annotations\2.5.65\analyzers\dotnet\cs\CSharpExtensions.Analyzers3.dll : Could not load file or assembly 'Microsoft.CodeAnalysis, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

The non-nullable properties are still being marked with a warning and we suspect it is of the error above.

Note: We are able to build the project with dotnet build without any problems.

We also tried installing Microsoft.CodeAnalysis version 3.5.0.0 to the project but we are still receiving the error.

Do you have any ideas on how to resolve this issue?

Thank you.

I opened a separate issue in Jetbrains. https://youtrack.jetbrains.com/issue/RIDER-50473

This is what I’ve got from VisualStudio 16.7.2 + R# 2020.2

It looks like R# has own analyzer related to the nullable types and it’s not supporting Roslyn suppressor but there’s an option to disable it:

The same option should be available in the Rider

I have no idea why your VS is not reporting CSE001 - probably this is caused by your local setup (maybe the installation is corrupted).

On my machine is working correctly with VS, RIder and don’t CLI

I really would like to help you but I can’t reproduce this issue.
