    if (app.SelectedItems.Count != 1 || app.SelectedItems.Item(1).ProjectItem.FileCount != 1) return;            
    var projectItem = app.SelectedItems.Item(1).ProjectItem;            
    var proyectoSW = projectItem.ContainingProject;

     if !(path.ToLower().EndsWith(".sql")) return;

     {                
         projectItem.DTE.ExecuteCommand("File.TfsContextExplorerMerge");            
     }            
     catch (System.Runtime.InteropServices.COMException)           { }
