Visual Studio 2013 (XAML?) Designer crash on all W

问题:

My designer started to crash, even on clean projects. The error message is as follows:

System.Exception
Package failed updates, dependency or conflict validation.

Windows cannot install package App.afbb198c1.a50af.a4b90.aa065.a08732a9e43b0 because this package depends on another package that could not be found. This package requires minimum version 0.0.0.0 of framework Microsoft.VCLibs.120.00.Debug published by any publisher to install. Provide the framework along with this package.

renewing the project->store->developer license does not help. What can be done about this?

There is no additional information in the Event Log about any of the happenings.

回答1:

It looks like you are missing some packages, you need to look into Nuget and see what packages are missing. Or with NuGet you can restore all packages in the solution using the command line.

nuget restore YourSolution.sln

Or Reinstall all packages in ALL PROJECTS of the current solution:

Update-Package -Reinstall

Reinstall all packages in SPECIFIC PROJECT of the current solution

Update-Package -ProjectName 'YourProjectNameGoesHere' -Reinstall
