i change the codebehind file, nothing happens

Question

In asp.net WebForms I make any changes to aspx.cs file, nothing happens. R# and IntelliSense are not working too on that tab. I even can write 'blablabla' anywhere, it won't cause any errors.

Seems like VS just takes the file from some other source, not the project folder, though the "CodeBehind" attribute in .aspx is written ok.

I also have this problem:

The designer.cs is not in .aspx branch and I don't know how to put it back, maybe these problems are somehow linked.

P.S. Sorry for my english :)

Answer 1

Delete the files (prefixed with index...) and re-create the index.aspx form anew :-)

Answer 2

If you opened it as a solution and not as a website you might need to compile after every change, but a better option, really, is to open the project as a website...
