With Resharper enabled, VS.NET shows all kinds of "Member with the same signature
is already declared" and red "Ambiguous invocation" errors in code behind
files. All references to a WebControl are highlighted with an "Ambiguous
reference" error. The "Analysis complete" message shows 21 errors and 2 warnings,
which makes me expect this should not compile, but it compiles without error.
Obviously, this is because of the funky ASP.NET 2.0 inheritance scheme, but
it makes editting a code behind file much more noisey than it needs to be.
