The Asp.net 2.0 program is downgraded to ASP. net1.0.

It is now in the era of. Net 3.5, but some people still use. NET 1.0.
A lot of machines are 2.0, so I found a very rare machine with 1.1 residual, but that machine also has 2.0.

The machine is a little slow, so when you open the project, you accidentally turn it into a project upgrade, the sun, the cancel is too late.

Upgraded, SourceProgramIt is damaged in a sense.

Microsoft has provided the upgrade program, but I have never heard of the downgrade program. The program has to be improved and changed. It is really a solution.

1.0 --> 2.0 changes:
1: WebService
2: pageload event
3: codebehind is changed to codefile
4: The class has become a special object.

How can this problem be solved?
1: rereference WebService
Use. wdsl to discover webpages
2: The pageload event must be re-registered in the init event.
That is + =, 1.0 is like this, and it's gone by 2.0.
3: delete codefile Registration
4: Delete the definition before the class.
