According to the documentation , Visual Studio 2019 is supported for use with the ArcObjects SDK in 10.8. A 10.8 project I built in Visual Studio 2017 builds, but the add-in for the project is not created. In the past, this has been a culprit of the ESRI.ArcGIS.AddIns.targets in the XML code of the project file as documented here. I'm familiar with this and have made these changes in the past, but couldn't figure it out quickly on my new computer with fresh installs of Visual Studio and ArcMap. So, I decided to just create a new add-in project from scratch in Visual Studio 2019 to look for any differences that could be causing the problem. However, on the Create New Project screen (see screenshot), I couldn't find any ArcGIS entries as described in the documentation here.
Next, I went looking for the ESRI folder within the MSBuild folder referred to in the second link, so now I'm wondering if perhaps the SDK isn't being completely installed with Visual Studio 2019 installations. Has anyone else used Visual Studio 2019 with ArcMap and ArcObjects 10.8?
Thanks
