Check that you don't have 2 files named global.asax. If you don't, try the steps in the above link. — Stephen Kennedy, Jun 13 '15 at 15:11

I think you shouldn't use the option of building assemblies for every page. You should build into a single assembly. If you use assemblies per page, when you deploy you should delete all assemblies in the bin, since they are previous versions and they have unique ids in the name, so they don't get overwritten.

In your case, clean your bin and then build. But I would suggest a single library for a full code-behind update, rather then specific code-behind updates for specific pages.

I have a huge project and I have many assemblies for each page — user2301941, Jun 13 '15 at 16:34
