I am working on a DLL application. I started this project using a trial version of Visual Studio 2010. In VS2010 can debug the DLL as follows: from the menu-bar select "Debug - Attach to Process...", I can then select the EXE that is using my DLL and click the button "Attach". Now, my company has purchased Visual Studio 2012. When I try to debug my DLL in VS2012, as I did in VS2010, I get a messagebox "A remote operation is taking longer than epected". I tried to solve this problem by using different settings (compared the settings with VS2010), no success. I re-installed VS2012, no success. Searched the internet on this topic , no success. Can you help me?
