Double-Loop in msbuild?

Question

I\'m writing a script for msbuild which should make two batches in one step.
Example: 2 ItemGroups

Answer 1

This is a much simpler solution.

    
        
            %(GroupTwo.Identity)
        
    

    

Using an intermediate Item group Combined to create an intermediate item group that the Message task batches on.

If you reference two Item groups in the same task, Msbuild will batch on them both separately. which is NOT what you want

If you have more ItemMetaData you'll need to handle that explicitly for the second ItemGroup, The ItemGroup included with the reference symbol @ automatically includes the ItemMetaData, so you'll just need to create the additional MetaData from the second group by referencing explicitly. Here's an example:

    
        One
    
    
        Two
    



    
        Andrew
    
    
        Bob
    



    
        
            %(GroupTwo.Identity)
            %(GroupTwo.Name)
