I think it is binding error in TextBox template tooltip

{Binding (Validation.Errors)[0].ErrorContent}

Validation.Errors become empty but binding still has not updated its references.

I recommend to ignore the exception. Uncheck "Break when exceptions cross AppDomain or managed...." in Debugging settings.

Answer 3

There are two different possible exceptions that get thrown from native code in this situation. Neither is caught by a try...catch block, no matter what you put (or don't put) in the catch.

One is "ArgumentOutOfRangeException crossed a native/managed boundary". To stop seeing this one, you need to uncheck "Break when exceptions cross AppDomain or managed/native boundaries (Managed only)" in Tools > Options > Debugging > General.

The other one is just "ArgumentOutOfRangeException". To stop seeing this one, you need to check "Enable Just My Code" in Tools > Options > Debugging > General.
