I am using:
VB.NET (visual studio 2015)
RestSharp v4.0.30319
Google.Apis.Core 1.20.0.0

This was working fine until I upgraded from Visual Studio 2010 to Visual Studio 2015. I also updated all the RestSharp and Google APIs as well as switched .NET framework from 4.5 to 4.6.1 (which it made me do when I upgraded the Google APIs.

So now when I run it I get the following exception on this line of code...

```
Dim credential As UserCredential = GoogleWebAuthorizationBroker.AuthorizeAsync(gclientsecrets, gscopes, "mysecretcalendar@gmail.com", CancellationToken.None).Result

```

and here is the error...

Managed Debugging Assistant 'BindingFailure' has detected a problem in 'C:\Voxeo\SERVICES\SERVICE DEBUGGER\IVRServiceDebugger\bin\Debug\IVRServiceDebugger.vshost.exe'.

Additional information: The assembly with display name 'System.Runtime' failed to load in the 'LoadFrom' binding context of the AppDomain with ID 1.

The system cannot find the file specified.

The project compiles just fine.
