I haven't had time to build a standalone solution to reproduce the problem so I don't have a great deal of new information, but I was asked to re-open things if it happened again, so here goes. I am using Entity Framework 6 within VS 2017 Enterprise edition. I'm using code first and I have database migrations enabled. In some cases (more detail below), trying to run any migration related command (via the Package Manager console) fails with the following error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Build.Framework, Version=15.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

Visual Studio For Mac TutorialMy solution is targeting.Net 4.5.2 currently. If you look at the original issue, there is a workaround whereby registering MSBuild DLLs into the GAC solves this issue - however it causes new problems so I am not using this workaround. I am using some extensions - ReSharper, NCrunch, WebCompiler, WiX toolset. The full stack trace of the error is: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Build.Framework, Version=15.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.
