Patterns should be preserved and unmodified when working with *proj files. If I specify a pattern with something like **/*.cs for my code files. If I add a new .cs file that fits that pattern the .csproj file should not be modified.
MSBuild already respects this, but the IDE will always modify the project file.
For numerous scenarios this could simplify the diff / merge process.4,213 votes
Hello everyone and thank you for the feedback. We are actively investigating ways to improve how Visual Studio handles project content. This suggestion falls into that category. Unfortunately, we will not be able to address this feedback for the Visual Studio 2015 release. We will update the community when our plans in this area have gained more clarity.
