Question

When you have code like this:

Something something = new Something();
BlahEntities b = new BlahEntities()    
b.AddToSomethingSet(something);
b.SaveChanges();

how do run that addition inside a transaction?

Answer 1

You can place your code within a Transaction scope

using(TransactionScope scope = new TransactionScope())
{
    // Your code
    scope.Complete(); //  To commit.
}

TransactionScope is in the System.Transactions namespace which is located in the assembly of the same name (which you may need to add manually to your project).
