I’ve seen this exception way too many times in Visual Studio 11 and 12… turns out that it is an issue with Azure SDK 2.2 – and my google-fu skills failed to find a solution online.
Could not load file or assembly ‘Microsoft.VisualStudio.WindowsAzure.Diagnostics, Version=126.96.36.199…
The fix turns out to be quite simple, once you see that error. This just means that the assembly cannot be found… so hey, just add it to your GAC like so:
Voila… problems solved.
