Expression<Func<T>> in parameter list always seen as Func<T>, can't pass p=>p.Name!!

I'm trying to create a method that takes a field name using the cool type safe format popular these days, but my calling code won't compile.

Here is the method:
 

public void MyMethod<T>(params Expression<Func<T>> propertyExpression)
{
    // extract property name from propertyExpression using 
    // whatever means, then use it to do some other stuff...
}

Select allOpen in new window

Now the calling code:

 

public string Name { get; set; };
obj.MyMethod(p => p.Name);

Select allOpen in new window

The problem is
A) It thinks I am passing a Func<T> to MyMethod(), somehow it isn't recognizing this is an Expression<Func<T>>!!
B) (probably because of A) the type of p isn't recognized and so it's members are not known.  If I let Visual Studio generate a stub, it generates this:

 

public void MyMethod<T>(Func<T> func)
{
}
