We're frequently (multiple times per day, multiple dev machines) receiving the following error trying to build various projects in our solution.

System.Exception: An exception was thrown in the remote environment: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> nCrunch.Common.UserException: Errors occurred while trying to load the project file:
Assets file 'D:\Source\Repos\Core\{Redacted}\obj\project.assets.json' doesn't have a target for 'netstandard2.0'. Ensure that restore has run and that you have included 'netstandard2.0' in the TargetFrameworks for your project.

Latest version of VS (16.9.3), latest version of NCrunch ( Am also submitting this within NCrunch itself which will hopefully give you some more debug info.

Happy to answer more questions about our project, but I'm unsure what's relevant at this point.

Hi Matthew,

Thanks for sharing this issue. Have you identified any pattern around when the issue appear? Things to watch for:
- The issue appearing right after VS is started
- The issue appearing after you update projects externally, such as after doing a git pull

My gut feel here is that VS is corrupting or partially reconstructing the project.assets.json file, and we're reloading it while it's either corrupted or in an incomplete state.

Something to check is whether performing a VS rebuild makes the problem go away.
