I want to pass the authentication cookie from my ASP.Net MVC 5 (.Net 4.5.1, hosted locally on iisexpress, run from Visual Studio) to my WCF Service (.Net 4.5.1, hosted locally on WcfSvcHost, run from same Visual Studio Solution) and decrypt it there. I have configured both to use the same machinekey (Web.config for ASP, App.config for WCF):
<machineKey validationKey="930681CA8CDC1BC09118D6B37E4A1B7712CEDBBD9FA1E35407EA1CD440C7E6F2DB9E93DADAC4098F90ACC7417DBE57C196722FC67F313A6AAE0F946E2FF731B6" decryptionKey="714C9581DA522C636B2D97D80276D5ACC02C274A11ABF117C76181B0480D4AEA" validation="SHA1" decryption="AES" /> Both reference the Same System.Web.dll:
> C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.1\System.Web.dll (v4.0.30319)
But when i try to pass the cookieString to my Service and call
FormsAuthenticatio ...
