How To Fix Missing Assembly Reference 'Microsoft.Xaml.Interactivity.dll' in Windows Store App Solution?
c#, catel, windows-runtime, windows-store-apps, xaml
Solution
Right click on your project => add reference => Windows 8.1 (tab) => select "Behaviors SDK (XAML)"
Problem
I have a Windows Store App solution which worked fine up until I installed Nuget Packages and Extentions from Catel. Now when I build the solution I get about 12 build errors with the following description originating from my startup project's .csproj file: Cannot resolve Assembly or Windows Metadata file 'Microsoft.Xaml.Interactivity.dll' One would think, remove then add the reference again but you cannot manage the framework's assembly references.
