Visual Studio Tools for Office Runtime
Visual Studio Tools for Office support statement
The Visual Studio Tools for Office (VSTO) Runtime Add-Ins platform is supported and serviced in Office with .NET Framework 4.8 as the last major version. If you have existing .NET Framework solutions that you're maintaining, there's no need to move them to .NET.
However, VSTO Add-Ins can't be created with .NET due to technical limitations with running .NET and .NET Framework in the same process.The VSTO platform will continue to use .NET Framework. You can take advantage of .NET, including ASP.NET Core, to create the server side of Office Web Add-ins.
The VSTO Add-Ins platform was built before today’s cross-platform world. To take advantage of opportunities with cloud-centered, cross-platform, and cross-device development, we recommend using the cross-platform JavaScript APIs. More can be found at Office Add-ins platform overview.
