I am migrating my application from net48 to net60. During the migration, I have to update my custom NuGet package to support net60 and add it to my application, but during the build, I am getting an error:
WcfWrapperGenerator.targets(36, 5): Could not load file or assembly 'System.Runtime, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
actual place where the error (line 36):
<GenerateWrappers ContractsAssemblies="@(_source)"
ContractsReferences="@(_references)"
OutputNamespace="$(GenWithNamespace)"
OutputPath="$(GenWrapperFilesPath)">
How can I fix it?
Also, I see an error, when trying to get code analysis:
Microsoft.VisualStudio.ProjectSystem.Query.QueryExecutionException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object.
