IIS Web site is not available: two different ASP. NET version issues running in the same IIS process

Error phenomenon:

Web sites that are just deployed in IIS can be used for a period of time. Then there is a hint that the Web site is unavailable.

To view the system log:

Found a message in the system log that "two different ASP. NET versions cannot be run in the same IIS process." Use the IIS administration tool to reconfigure the server to run the application in a separate process. ”

Solution:

Because two ASP. NET versions cannot be run in the same IIS application pool. assigning different ASP. NET versions of sites to different application pools is fine.
