In Visual Studio 2015 we are piloting a recurring and cumulative servicing update that provides fixes to high-impact bugs between our regular updates.
In the second servicing update recently made available, we fixed an issue in Visual Studio 2015 Update 1 that can cause Visual Studio to crash sometime after editing C# or Visual Basic files while debugging. You can get this fix now by downloading the servicing update for Visual Studio 2015. All of the fixes that are provided in this update will be rolled into future updates as well.
