Ok, well that's that... The installation requirements don't tell you the important bit. which is listed here.... it won't run in Medium Trust. We that's a wasted half day :-(

Anyway, for the record, this is how you get to discover the above problem; all edits to the web.config of BugNET, also follow existing install instructions.

(1) Remove
    <configSections>
    <system.web.extensions> (empty anyway)
    <system.webServer>
 Plus any references to  System.Web.Extensions and  AjaxControlToolkit

(2) <!--Patch for asp.net version problems.-->
    <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35"/>
                <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>
            </dependentAssembly>
            <dependentAssembly>
                <assemblyIdentity name="System.Web.Extensions.Design" publicKeyToken="31bf3856ad364e35"/>
                <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>
            </dependentAssembly>
        </assemblyBinding>
    </runtime>

(3) Change AspNetSqlMembershipProvider to use existing site's membership provider (leave profile provider alone).

(4) Set all files on live application to be 777 (read/write/modify). Add Impersonation for Mosso:
         <identity impersonate="true" userName="XXX\***" password="***" />

(5) Run: http://www.health-analytics.co.uk/BugNET/Install/Install.aspx

It actually connects to the database and looks promising, finally failing on:

[SecurityException: Request for the permission of type 'Permissions.FileIOPermission

Well it's still looking pretty bad, even with the above stuff all done. I kind of need a lot of stuff in the newer releses of .net - hell, I need 4.0 actually.

2 Live Environment

I'm actually backing backing off on the same membership provider as my parent site (shared between live and test), so that's common. Here everything's IIS7/ SQL 2008, all latest versions, but we have the cluster things to deal with plus Medium Trust. I run other open source stuff (YAF, BlogEngine.NET) with this no problem.

On Rackspace Cloud / Mosso it won't install with what I think is the trust problem, as below.  I'm not sure what it's doing when it spits this out.

However, as a devious person, it occurs to me that the install presumably sets stuff up in the database, and as I only have one database (so that's one test server, one live clustered server, and a third server for the defects database and membership provider database), if I can get it to install using my test machine (full trust), then I don't need to install it twice as the backend is shared. That's only true so long as you don't have any other persistent state around the install..... ?

If I try that (Install from test machine to backend database), well it fails as above, and then if I try to run it on live I'm getting a version conflict on the Ajax controls again which maybe I can fix.
