.NET Installer Problem and Fix

[Andy Morsell]

I believe this was a problem for some .NET web extensions installs in the
0.91 release, but I just ran into it on a fresh install of 1.0 on Windows
2000 Server IIS.  The symptoms: when running the sample .NET application,
you get the following error (you may first have to turn on custom errors in
a web.config file):

Server Error in '/mapguide/dotnetviewersample' Application. 

The path '/mapguide/dotnetviewersample/App_GlobalResources/' maps to a
directory outside this application, which is not supported. 
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information
about the error and where it originated in the code. 

Exception Details: System.Web.HttpException: The path
'/mapguide/dotnetviewersample/App_GlobalResources/' maps to a directory
outside this application, which is not supported.

Either the web extensions installer or IIS adds a backslash to the main
application definition in IIS.  In IIS, right-click on the mapguide virtual
directory, go to Properties, and then look at the local path value.  If you
are getting this error, it will probably read: C:\Program
Files\MapGuideOpenSource\WebServerExtensions\www\.  Delete the final
backslash after www and that should fix the problem.
