[215] Ambiguous/duplicate class references with old-style .ascx file Follow

..ascx files have been showing up with a duplicate class definition error
for a couple of versions now. Resharper is picking up the .ascx and the
.ascx.cs as two separate instances of the class.

.NET 2.0 allows the "old style" to co-exist with the newer style of
.ascx. If the codebehind class is partial, it seems to use the new
style and creates a new partial class. If the codebehind class is not
partial, it uses the inheritance model instead.

Is this a known issue?
