Parser Error Message: Could not load type 'webmarketing'

Solution 1:

I had same problem before i just change CodeBehind to CodeFile and it worked.I remember it works in local but i had this problem after uploading.

Solution 2:

This is normally happening when you copy files from a Web application projects to Website Project.

When you create a Web Application the Page directive is CodeBehind for the web pages.

If you create your application as Website then the Page directive is CodeFile

So if you copy from a Web application to Website the Namespace as well as the page directive will not change automatically, you should do this manually to rectify this error.

Solution 3:

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.
