Run your ASP. NET application back to. NET Framework 1.1

Some may encounter a problem: an ASP. NET application has been developed in the. NET Framework 1.1 environment. After being upgraded to. NET Framework 2.0, an inexplicable error occurs and the application cannot run normally.
This problem also occurred when I used the Enterprise Library EntLib1.1 (June) to Develop ASP. NET applications. After several twists and turns, I found a solution. I hope to share it with you.

The solution is easy. You only need to configure IIS!
The procedure is as follows: Open IIS-> right-click the application directory and choose "properties"-> select "ASP. NET tab-> in ASP. select version 1.1 from the drop-down list box.

Hope you can get a solution faster if you encounter the same problem!
