Question

I am facing problem in porting my Silverlight based solution from VS 2008 to VS 2010.

 Error : "Association is marked with RequiredAttribute. Please remove the attribute and mark the underlying foreign key members with RequiredAttribute instead."

And I am unable to locate that where to set/reset this RequiredAttribute in Association.

Note : I am using Linq to Sql for data objects.

I have checked metadata, dbml designer and its Xml too.

I have moved my projects from .netframework 3.5 to .netframework 4.0 and Silverlight 3 to Silverlight 4.

But still I am not able to build it.

Hi SanjayGupta2110,

Welcome to MSDN Forum.

Based on the issue, could you please upload the project to SkyDrive and post the link here? I will test the code and help you to find the root cause.

Hi SanjayGupta2110,

I'm afraid I can hardly help you to find the root cause without the code. Could you please write a demo?

Best Regards
