Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I have created a small .Net 4.0 website and installed it on my SharePoint server as a separate web site in IIS v7 (using port 8008 for now). I had to install the .Net 4 framework, set up the database, etc. and this all went smoothly and my app works as a standalone website.

Now I am trying to get pages from my website to show up in SharePoint 2007. For various reasons (the SharePoint site is using SSL, security, etc.) I now need to move my .Net app to run under the SharePoint 2007 site in IIS. I have added it as an 'Application' and set it up with the same .Net v4 application pool and settings that were working when it was set up as a standalone site.

Now when I try to access the application I get the error at the end of this description. Any help would be greatly appreciated. I already tried following the instructions on this post:

but that did not help.

Here are the error details:

Officially I don't think this configuration is supported yet. See the ASP.Net 4 breaking changes whitepaper.

Unofficially, you should be able to fix the problem by changing the trust level in your web.config file from WSS_Minimal to Full. This is NOT recommended though.

Thanks MattB, I had tried setting the trust level to Full and that did not seem to help, although I might have other problems. The link you supplied does seem to preclude what I am trying to do... –  Craig Nakamoto May 12 '10 at 18:44
    
@Craig: did you try in your local apps web.config, or in the SharePoint web.config? I think it has to be at the SharePoint level, but not sure. –  MattB May 12 '10 at 19:46
    
I only tried my local web.config, but I have moved on now and will just set up a separate ssl certificate for my app. Thanks again Matt! –  Craig Nakamoto May 12 '10 at 20:02
