In Visual Studio 2015, there are additional methods being delegated to our source control VSPackage, which is the not the case with Visual Studio 2013.
Use Case 1: Opened a source controlled C++ console app solution in Visual Studio 2015 IDE. Once done, I dragged and dropped an uncontrolled .c file from my workspace to the IDE. Please note that this file is not a part of currently active solution. Now I try to close this file. I see a call to OnQueryRemoveFiles, which is not the case with Visual Studio 2013. In Visual Studio 2013, I see a call to this method, only when we try to remove a file from a solution .
Use Case 2: Opened a source controlled C++ console app solution in Visual Studio 2015 IDE. I have a tool window active to show pending checkins. Once done, I dragged and dropped an uncontrolled .c file from my workspace to the IDE. Please note that this file is not a part of currently active solution. I see a call to OnAfterAddFilesEx, which is not the case with Visual Studio 2013.
if this is an expected behavior, would prefer to know the list of methods which had been modified and reason behind same.
