+Summary: ProvidersHelper can not load type from App_Code assembly [w/ fix]
+
+Description of Problem:
+Created a custom Membership and Role provider for my site by creating these
+classes under the App_Code directory.  Currently with a fresh version from
+SVN, the application fails to load the provider as it can not find the type
+in any assembly.
+
+Steps to reproduce the problem:
+1. Create application with custom provider defined in the App_Code directory
+2. Try to access the site
+
+Actual Results:
+An error is thrown indicating that the type can not be loaded.  The stack
+trace points to the ProviderHelper.InstantiateProvider(x,y) method.
+
+Expected Results:
+Page loads, and provider is usable.
+
+How often does this happen? 
+always
+
+Additional Information:
+I have tracked this down to the ProviderHelper not finding the App_Code
+dll.  I have included the patch below which addresses this issue, by
+looking in the App_Code assembly if it was not found using the existing
+checks.  The following is the patch illustrating this, and is similar to
+another bug I reported here:
+http://bugzilla.ximian.com/show_bug.cgi?id=78797.  It uses the same
+technique to get the reference to the App_Code assembly - via the BuildManager.
+
+Here is the diff:
