I have installed API for using new feature of C# 5 but some strange things happens.
i am able to use async keyword but VS 2010 tell me that "Can not find Task-Related types.Are u missing to a reference to AsynCtpLibrary.dll ?"
And also i see some errors on compile time like " compiler required member 'System.Runtime.CompilerServices.AsyncMethodBuilder.Create'"
Where is AsyncCtpLibrary.dll ? It fix my problem to add it to reference ?
