ASP.net app crashes - Could not load file or assembly 'Microsoft.Threading.Tasks.Extensions.Desktop'

Question

I want to build a Google BigQuery C# ASP.net application using OAuth2 and the .Net 4.5 framework. I ran these NuGet installs

Install-Package Google.Apis.Bigq         


        

Answer 1

Because the error is based on the fact that the latest version of Microsoft.Bcl.Async doesn't work in .NET 4.5, you can try to do the following:

Open your Package Manager Console, and run the following commands:
1) Uninstall-Package Microsoft.Bcl.Async -Force
2) Install-Package Microsoft.Bcl.Async -Version 1.0.16

It works in a sample I'm currently writing. Please let me know if it works for you.

UPDATE (March 21st): You can update the package (new version 1.0.166-beta is available - https://www.nuget.org/packages/Microsoft.Bcl.Async/1.0.166-beta).
I tested it on VS2013 with .NET 4.5 framework and it works.
