  3. Had the similar issue, and following worked for me, sharing if people are still facing this issue:-

    had to mark the Specific Version = False for the following References in the TEST project

    Microsoft.Data.Tools.Components
    Microsoft.Data.Tools.Schema.Sql
    Microsoft.Data.Tools.Schema.Sql.UnitTesting
    Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll

    do not set Specific Version = False for the following reference, not sure why but it breaks the test project, and it stays unloaded unless you fix the property in the project code manually.

    hope it helps.
