I have a compiled website and now I need to make some changes to the code behind vb file. When I open a website in Visual Studio it gives me a message "You are trying to open a precompiled website." I have tried several different things but it does not recognize any changes I make to code behind file. I don't have any experience with code behind file so I am not sure what to do. When I build it, it says its recompiled and when I try to publish, it gives me a list of errors (errors posted in jpeg file). I would really appreciate any help.
