I’m involved in some EF 4 development now and I ran into an error I couldn’t understand. Fortunately I wasn’t the first to experience this so it could be solved. However this is an example of an error description that could have been clearer.
The error was:
“Cannot convert lambda expression to type 'string' because it is not a delegate type”
The solution was:
Add the System.Linq using statement to the code……
I found the solution here.
