Using other build systems
If your build system isn’t Visual Studio and msbuild, you can determine the changes you need to make to your own build system for cross-generation development by comparing the XBOX Series X|S and XBOX One versions of the msbuild .targets and .props files that the GDK includes. You install these files to theGaming.Xbox.Scarlett.x64 and Gaming.Xbox.XboxOne.x64 directories under C:\Program Files (x86)\Microsoft GDK\260400\GXDK\VS2019\flatDeployment\MSBuild\Microsoft\VC\v160\Platforms.
For more information about the specific settings that are needed to build without using Visual Studio, see Microsoft Game Development Kit porting guide for XBOX One.
