How to bulk update using LINQ?
I have a scenario where I need to update multiple records, preferably using LINQ. For example, I need to update a list of SSRS reports that a user can view. I have a many-to-many junction table setup, iw_UserSSRSReport, in the database between the iw_SSRSReport and aspnet_Membership tables (see attached screenshot).
How would I insert/update the records in the junction table? I am still in the planning stage so I haven't written any code, but I foresee an issue running into this.
Do I need to add the User Id and SSRSReport ID to a collection and pass that to a method as a parameter, and then loop through the collection and inserting the items individually, and then calling SubmitChanges()?
And how would I update? Would I have to first clear out the junction table where that user id exists, and then execute the same insert method?

Are you using LINQ to Entities or LINQ to SQL? Then it shouldn't be a problem.
