Version Information: Microsoft .NET Framework Version:1.1.4322.2407; ASP.NET Version:1.1.4322.2407

It took me some efforts to resolve this issue…

First of all, after some investigation, I found in IIS manager, our sharepoint site is pointing to ASP.NET framework 1.1. The fix will be adjust it back to ASP.NET framework 2.0 (Just right click the web site -> Properties->ASP.NET tab ->Choose the correct framework)

Now I re-render it again. This time I got page cannot be found error…Argh….so I tried re-registering ASP using Aspnet_regiis.http://msdn.microsoft.com/en-us/library/k6h9cz8h(VS.80).aspx

And then render the page again…now I got this error:

CS0016: Could not write to output file ‘c:\WINNT\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\a0f950ac\3f897461\fr-fr\App_GlobalResources.k8ft-2zy.resources.dll’ — ‘The directory name is invalid. ‘

OK, babe…whatever..This clearly indicate that the folder Temporary ASP.NET Files does not exist. So I went to My computer ->Properties->Advanced->Envrionment Variables. Make sure the folder System variables TEMP and TMP is pointing to exists on your computer and Network Services and aspnet accounts have full control of it.

Then after an iisrest and long wait, my dream portal finally appears on the screen!
