After a recent update, Resharper started to remove using statements in my c# code which were there to prevent an ambiguous reference error in Visual Studio.
For example, I have a class which uses both System.Windows and System.Windows.Forms. In that class I have a method that creates a MessageBox object. Since there is a System.Windows.MessageBox and a Systems.Windows.Forms.MessageBox, Visual Studio shows an error since this is an ambiguous reference. In addition if I put the full path, System.Windows.MessageBox, at the place where I'm using it, Resharper removes "System.Windows" saying it's redundant. If I try to build the project, I can't because there are errors.
Resharper will stop removing these items if I uncheck "Optimize 'using' directives" from the Code Cleanup settings, but I'd like to leave that enabled since it does other things that I do want it to do.
Let me know if there's something I'm missing or if you need more information.
