Webcontrols type mismatch

[Quentin Snow]

I have framework 1.0 and 1.1 installed.

I downloaded the WebControl source code and recomplied.

When I try to compile the souce code using the CSC.exe from Framework 1.1
installation I get an error. If I use the CSC.exe from the 1.0 Framework
installation it compiles fine.

I then add the reference in VS.Net to the webcontrols.dll file and recompile
my solution. I am now getting the following error when I try to view the
webpage.

Is this caused by compiling the Webcontrols with the 1.0 framework
installation?
