Publishing ASP.NET 1.1 App to Windows Sharepoint Services Web Site

Yesterday I built a small web site and I tried to publish it to my usual web site  This site has been entirely running Windows Sharepoint Services until now.  I used Sharepoint Central Administration to exclude my virtual directory from WSS and I ran my MSI installer on the machine.  The WSS web site is the default and my MSI which was created with Visual Studio .NET 2003 only installs to the default web site.  My server is running Windows Server 2003 and is also a domain controller.

Well it all turned to custard and I had to create a new web site on the machine, differentialted by a new host header.  So now to isntall updates I have to run the MSI and then manually copy the files from the default web site to the alternate.  Also, I can't use the dotnetlounge URL.

How can you install an ASP.NET application to a virtual directory that's under a Windows Sharepoint Services web site?

Here's the error that I got.  Clearly my web site can't get System.Web.AspNetHostingPermission.  I played around with the settings for a while and did a few google searches but no result so far.   I believe it's something to do with the custom security settings created by Windows Sharepoint Services, the web site isn't on a network share.

I'll keep researching...

    As you know (or maybe not?), when you extend a virtual server for WSS, WSS imposes a number of WSS-specific extentions basically taking over the virtual server that’s running your WSS site. If you want an ASP.NET app to run in a directory within your WSS web, you’ll need to deploy your app under the "_layouts" directory in your WSS web. It’s important that you do this so that WSS won’t try to content for your site in the WSS content database.

    That would be the first thing I try to make sure that your app at least runs correctly.

    Are you also trying to redirect to your app when you enter

    To Lamont: Thanks for replying I did know all that. I had thought that the Exclude Directory command would allow me to bypass the WSS addins. Layouts dir is no good for me – I don’t like the resulting URLs. You can also put .ASPX pages into document libraries and run code there. I have ended up deploying to instead.

    Really sucks that you had to go that route. Product enhancement request anyone? 🙂

    I thought that using the CSP provider and strong-naming the app, then adding the .DLL to the GAC on the WSS box, would be enough to avoid the ugly workaround you did.

    I think, though, that I was wrong; it seems to be a simple enough ask to be able to enumerate all subwebs from a WSS site via ASPX 1.1, esp. using SOAP against some of the builtin Web Services that come with WSS. That is what I am attempting to do; I’d like to populate a dropdown in a signup form for several subsites all running WSS. However, I run into the same (security) issues as you seem to have and I am likewise unwilling to put all apps that need to access the Sharepoint Object Model in _layouts.

    Any breakthroughs in your research, I’d appreciate hearing back:

    Actually, I managed to cajole my app into working. The trick was to create a trusted code group by URL and add my (WSS excluded) app to that group (also have the .DLL in the GAC which is probably redundant). It is fairly ugly I grant you, but it works without having to move the app into _layouts or using a non-WSS URL. HTH,
