System.Data.DataSetExtensions Exception in VS 2008 RTM

Category:Bil@l @ 21:15

I got the exception shown below when I opened an application that was developed under VS 2008 beta 2:

ASP.NET runtime error: Could not load file or assembly 'System.Data.DataSetExtensions, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified


What happened is that, there is no more an assembly System.Data.DataSetExtensions with version number 2.0. There is a new version for the same assembly name under

To resolve the problem, simply right-click on the web application, properties, then remove the reference to the assembly.

Then, right-click on the web application solution, Add Reference, locate the System.Data.DataSetExtensions and add a reference to it. This shall solve your problem!
