since updating to the all new and "stable" XamarinVS 4.2.0, Cycle 8, Visual Studio greets me with
An exception was thrown while initializing part "NuGet.PackageManagement.VisualStudio.VSSolutionManager".
After that, all components are marked as "incomplete". Needless to say, that compiling fails, too. This happens whenever I am opening a Xamarin.Android project using the usual Android Support Library components. Also, the same message appears whenever I try to open the NuGet Package Manager Console.
My Visual Studio version is
Microsoft Visual Studio Community 2015
Version 14.0.25425.01 Update 3
Microsoft .NET Framework
If I close Visual Studio and restart it with a plain old Windows .NET project with NuGet components everything works fine. But as soon as I open a Xamarin.Android project the message appears again and again.
Anybody got a cure or work-around for this, except downgrading to the previous Xamarin release?
