Description
Environment
SaaS (https://sentry.io/)
Steps to Reproduce
When building UWP project using Azure DevOps Pipelines we got this error:
Error CS8032: An instance of analyzer Sentry.SourceGenerators.BuildPropertySourceGenerator cannot be created from C:\Users\svcprd_tfbuild.nuget\packages\sentry\5.15.1\analyzers\dotnet\cs\Sentry.SourceGenerators.dll : Could not load file or assembly 'Microsoft.CodeAnalysis, Version=4.3.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified..
Microsoft.CodeAnalysis Version=4.3.0.0 is not available in Nuget repository.
Sentry Version=5.15.1
EDIT:
TreatWarningAsErrors is set to true, so this error is acutally a warning:
CSC : warning CS8032: An instance of analyzer Sentry.SourceGenerators.BuildPropertySourceGenerator cannot be created from C:\Users\svcprd_tfbuild.nuget\packages\sentry\5.14.1\analyzers\dotnet\cs\Sentry.SourceGenerators.dll : Could not load file or assembly 'Microsoft.CodeAnalysis, Version=4.3.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

Thanks @KrzysztofFryzlewicz for reporting this issue.
One aspect that catches my eye is that you mentioned using
v5.15.1of the SDK,but the error contains
\5.14.1\.Not sure if there is a restore issue, or just a message from a build before the version update.
Anyway, we need a bit more info about the environment to reproduce the error:
I have the feeling that this is less of an UWP problem, but more of an issue related to compatibility with MSBuild and the available Roslyn Compiler version.

@Flash0ver yeah, issue exists in 5.14.1 and then I upgraded the package to see if this resolves anything, but no luck.
MSBuild version: 16.0
Visual Studio 2019
We excluded this warning and build seems to run just fine.

I like the latter one, perfect!

I'd like to keep it open, at least for now, as we do indeed need to support building supported Projects from Visual Studio 16.11. May merge later into #4305.
