    Thanks for the show. I am getting following errors when compiling classLibrary solution. I have installed the nugget packages. Any ideas?


    Error 2 The "DllExportAppDomainIsolatedTask" task could not be instantiated from "C:\Download\DefragTools\ClassLibrary1\packages\UnmanagedExports.1.2.6\tools\RGiesecke.DllExport.MSBuild.dll". Could not load file or assembly 'RGiesecke.DllExport.MSBuild, Version=1.2.6.36228, Culture=neutral, PublicKeyToken=ad5f9f4a55b5020b' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515) MyExt
    Error 3 The "DllExportAppDomainIsolatedTask" task has been declared or used incorrectly, or failed during construction. Check the spelling of the task name and the assembly name. MyExt

    hi imak, were you able to resolve this issue? I am encountering same error after compiling Andrew's class library.

    Instead of using my project, maybe try the nuget package import yourself. That might fix it.

    actually don't worry about it. That was my bad, didn't copy diagnostics file in the windbg folder. After copying, it worked like a charm :)
