Hello everyone,
I have a solution with a web site and also a class library with a control which inherits from the WebControl class. When I place the control in the toolbox and use it in the web site, I can no longer build the solution - Visual Studio (the compiler) complains about the class library DLL being used by another process (which I suspect is VS itself).
Is there a way to develop and use a custom ASP.NET web control in a single solution? Or am I missing something here?
