The type cannot be created after ashx is deleted by mistake, and ashx cannot be created by mistake.
Description

Today, because of temporary issues, you need to take a trip to other cities, and the project is quite busy. So I can only continue Typing Code in the car. The unlucky touchpad allows me to accidentally delete a general ashx handler. The code for this file is still very long.

My approach is to [recycle bin] → [restore] → [Include in project] In ]. Thought it was done.

Then the error message "failed to create type..." appears ......

Rough experience

I have found many posts on the Internet, but it is not necessary. It seems that none of them match. Later, I ran to the MSDN developer community. I saw this scene.

It can be said that my heart collapsed when I saw this scene.

Solution

Later, I had a hard time thinking. I think so.

[Failed to create type] It must be because of my type, which has already appeared in the Assembly. All I have to do is clear the compiled results.

Then I found the local folder of the website and deleted all files under [obj] → [Debug. Then re-compile and F5 start debugging.

OK ~~~~
