Question

I want to have a function to something similar:

public static V callAsyncAndWait<V>(Func<V> func)
{
    ThreadPool.QueueUserWorkItem(obj => 
    {
        V v = func.Invoke();                 
    });

    return v;
}

Obviously this code doesn’t compile. What I want is to run the Func in another thread and return the result. How can I do that?

I recommend you to use the new .NET 4.0 Task class instead. Here is a tutorial on how to return a result from the execution of Task: http://msdn.microsoft.com/en-us/library/dd537613.aspx

Practically you have a very convenient property called Result, which, upon invocation of the getter, will block until the result is available.
