Modify MSBuild ItemGroup Metadata

Question

Is it possible to modify a ItemGroup\'s metadata after it is declared.

For Example:

Answer 1

I tried using the UpdateMetaData TaskAction from the MSBuildHelper task in the 4.0 extensions pack but it didn't do what I expected so I went with the remove/replace method. In this example I'm trying to update the DestinationRelativePath metadata property in the FilesForPackagingFromProject item group.

    

    
        
            $(CopyAllFilesToSingleFolderForPackageDependsOn);
            SetFilePathsToRoot;
        
    

    

        

        
        
            
                %(FileName)%(Extension)
