1%. Is it a valid Win32 application?

Using CLR profile todayProgramIs used to monitor the memory allocation of the website, but the website reports the following error:

1%, not a valid Win32 application,

Before using the CLR Profile Program, website access has been normal.

I searched the internet for half a day, but it was fruitless.

Inadvertently found in the c: \ windows \ Microsoft. NET \ framework \ v4.0.30319 directory

The Update Time of the csc.exe file is today and the size is 0 KB. Therefore, it is suspected that the file is being updated by the CLR Profile Program.

Destroyed. I copied a new file from my colleague and overwritten it. The problem is solved.
