title: BuildTasks.Csc task could not be loaded from the assembly?
body: <p>I feel guilty asking a question like this around here, but I'm at a loss and would appreciate some help.</p>
  
  <p>A proof-of-concept like web application was built on one PC and put up on a repo to download on another PC at a different location. There was originally an auto-build feature set up where Azure would build and publish automatically on check-in, but that was removed. Things were working on both ends until one side included a bulk of excluded changes. Now I'm seeing the following error:</p>
  
  <blockquote>
    <p>The "Microsoft.CodeAnalysis.BuildTasks.Csc" task could not be<br>
    loaded from the assembly
    ...\packages\Microsoft.Net.Compilers.1.0.0\build..\tools\Microsoft.Build.Tasks.CodeAnalysis.dll.
    Could not load file or assembly
    'file:///...\packages\Microsoft.Net.Compilers.1.0.0\tools\Microsoft.Build.Tasks.CodeAnalysis.dll'
    or one of its dependencies. The system cannot find the file specified.
    Confirm that the  declaration is correct, that the assembly
    and all its dependencies are available, and that the task contains a
    public class that implements Microsoft.Build.Framework.ITask.</p>
  </blockquote>
  
  <p>Does anyone have any suggestions on where to begin looking for the issue?</p>
