Developing latest version of MojoPortal I checked out today using TortoiseSVN from  https://forgesvn1.novell.com/svn/mojoportal/trunk

Running on Widows XP SP3 & SQL Server 2005.

I loaded the mojoportal.sln in VS 2008 and performed a Build for the entire solution after I set up the db, and got the following errors:

Error 1 'System.Web.UI.HtmlControls.HtmlForm' does not contain a definition for 'Action' and no extension method 'Action' accepting a first argument of type 'System.Web.UI.HtmlControls.HtmlForm' could be found (are you missing a using directive or an assembly reference?)

Any help guys? The version I had was mojoportal 2.3.1.3 and was working perfectly.

Thanks very much Joe on the earlier reply, but I have now run into a bigger dillema.

After you advised to update to .NET 3.5 SP1 I got the following issue, btw I should mention I was able to successfully build the solution after the update with no errors but this is what happened instead:

 

I downloaded and installed .NET 3.5 SP2 happily turned off my PC and came back today, only to find that not only does the application doesn't work, but I keep getting this error:

 

"Unable to connect the ASP.NET development server"

 

Now to make things even more confusing I read almost every post on this and nothing helped, I copied my WebDev.WebServer.exe (after receiving an error when attempting to manually run it) file from my VM running everything similar to my box except for MS Server 2003, and got a different error.

Now I would really appreciate it if someone helped me know what exactly was the catalyst to my current dillema.

Update: I attempted to create a Virtual Directory in IIS in a weak workaround assuming I had a problem with the VS 2008 built in Server, and got this message:

Could someone please tell me what all of this nonsense means?

Thanks for the timely reply Joe, I'm not sure if that was the problem, I updated my VS 2008 to VS 2008 SP1 and everything is back to normal. I'll look into it with more detail and let you know what happened if I ever figure it out myself. Many thanks
