5.0.9 error on Exchange code for access token

问题

I've followed "Getting Started with an ASP.NET MVC 3 Website" and it has worked fine (5.0.8) until I updated the SDK to 5.0.9.

I've got this error when trying to exchange code for access token:

Unexpected character encountered while parsing value: a. Line 1, position 1.

It occurs at

dynamic tokenResult = oAuthClient.ExchangeCodeForAccessToken(code);

The "code" is correct as it used to be.

Any ideas?

Thanks

I had the same problem, I solved it downloading the source code from CodePlex and compiling again the Facebook.dll. With the one that I downloaded from NuGet I had the same problem that you are having now.
