"Cannot find assembly" problem with .NET 1.1 and 2.0 coexisting

[Nils Magnus Englund]

Hello,

In the root of a web site (C:\Inetpub\wwwroot), I have a .NET 1.1
application. I've just added a .NET 2.0 application to another directory
under the web site root (C:\Inetpub\wwwroot\20App).

After restarting the IIS server, the 1.1 application works fine - however,
when I first request a page from the 2.0 application (which also works fine,
by the way), the 1.1 application stops working. Every time I request a page
from the 1.1 application, I get the following exception:

Cannot find the assembly App_Code.whenpsq7, Version=0.0.0.0,
Culture=neutral, PublicKeyToken=null.

Restarting the server (recycling the application pools doesn't work) makes
the 1.1 application available again.

Any ideas what could cause this? Thanks for any help!


Regards,
Nils Magnus Englund

If you are facing this problem on Windows 2003 server, then read this
article. It may answer your question.

Yes, I am running Windows 2003... However, I do have a separate application
pool for the individual .NET 2.0 application I have. All other applications
are in the DefaultAppPool.

Thanks.

Same Problem

I am having this problem... I'd like to know what the heck is going on because it is causing major problems for me. I placed the application in its own pool. Asp .net 2.0 is installed but every site is running under 1.1 ... so wtf? I appreciate any clarity that someone can provide.
