Consider using MSTest.Sdk or MSTest metapackage, or at least use MSTest.Analyzers

[Youssef1313]

Currently, MSTest analyzers are not used in this repo. You can consider using them by adding a reference to MSTest.Analyzers (with PrivateAssets="all"). Or use MSTest metapackage which includes all the needed dependencies, and then you will no longer need to have multiple package references related to testing.

Or you can even go further and use MSTest.Sdk.
