Parser Error Message: Could not load type 'webmarketing'

Question

After finishing the web application and publishing it online no matter I try I keep getting the following error, keep in mind that it runs locally as it should...

Answer 1

I had this error message. The problem was my .cs and aspx files were not added to the project. They were in the folder, but were not added. I solved it by adding them to the project (right click, Add). And then after I built the project, it was compiled into a dll in the bin folder. There was no need to change the text from CodeBehind to CodeFile.
