Failed to load type "XXXX. Global"

Compiling ASP. NET today ProgramThe server encountered a strange problem: the server could not process the request; the "program name. Global" type could not be loaded. This problem was not encountered before, so I went online to Google. See ArticleIt may be because the project was not compiled successfully. I thought there was indeed an error during the compilation, but I chose "continue" and the previous error occurred. After going back, the error is solved first so that the compilation is successful and the error does not appear again. That's the problem.
