Question

I am looking into resolviong Asp.net Webapi CORS issue with Thinktecture.Identitymodel as described in this URL
http://brockallen.com/2012/06/28/cors-support-in-webapi-mvc-and-iis-with-thinktecture-identitymodel/

I am using VS2012 with .Net 4.5
I am coming across a couple of problems here:

1) This is the error I am coming across when i make a request

Attempted to access an element as a type incompatible with the array
An unhandled exception occurred during the execution of the current
web request. Please review the stack trace for more information about
the error and where it originated in the code.
System.ArrayTypeMismatchException: Attempted to access an element as a
type incompatible with the array.

+159 System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest
wr, HttpContext context) [phone]

My application pool is pointing to Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.17929

2)My second question is after doing things as mentioned in WebApi. Do i still need to add HTTPmodule for IIS?

Its should be very easy to get going with this. I don’t know what I am missing here.
Any pointers are highly appreciated.

Thanks.

Answer 1

I figured out that I had a version mismatch of assemblies . My actual project was in .Net 4.0 and Thinktecture was in .Net 4.5 .

Once i fixed that it worked.
