FileLoadException when placing SignalR on a working Azure role with F #

I try to run my own SignalR host server as a working Azure Windows Agent, but keep getting

System.IO.FileLoadException: Could not load file or assembly 'Microsoft.Owin, Version = 2.0.0.0, Culture = neutral, PublicKeyToken = 31bf3856ad364e35' or one of its dependencies. The installed assembly manifest definition does not match the Help assembly. (Exception from HRESULT: 0x80131040)

When I run the same code in a console application, it works fine, and everything works as expected. The entire working role is written in F #. Below is the shortest code that throws the exception I'm talking about:

override wr.Run() =
    let x : IAppBuilder = null

    x.MapSignalR() |> ignore // this line throws the FileLoadException

exception

  • From there I had to clean up the Owin assembly nodes. My Owin assemblies did not load from the NuGet package directory and thus downloaded 2.0.0.
