Can't use System.Runtime. Remoting.Channe ls.Http in WebService?

[Kirk]

I'm trying to use a Web Service to be a Remoting client of an existing
..NET 2.0 server. But I get the following error when I try to use
System.Runtime. Remoting.Channe ls.Http in my WebService. The same code
works fine in a standalone app. I have inspected
System.Runtime. Remoting.dll with ildasm, and I can see the
....Channels.Ht tp namespace there. I verified that the virtual
directory is configured to use v2.0.50727 (the error message confirms
this). Am I missing something?

Thanks,
Kirk

I noticed that on my web server, all my file associations for aspx,
asax, ascx, etc. all point to v1.1 of the framework. I installed the
2.0 framework on that machine, but it apparently didn't update all the
file associations. Is there something I can run to update them? Is it
possible this is the source of my problem?

Thanks,
Kirk

Well, I figured out my original problem. I needed to add a reference
to the assembly System.Runtime. Remoting in my Web.Config as follows:

<assemblies>
<add assembly="Syste m.Runtime.Remot ing, Version=2.0.0.0 ,
Culture=neutral , PublicKeyToken= B77A5C561934E08 9"/>
</assemblies>

Visual Studio 2005 can do this for you if you right click in the
Solution Explorer and select Add Reference...
