Visual Studio 2026 Compatibility?

Vidar — Tue, 24 Feb 2026 09:28:15 GMT

Hi,

Was just wondering what the plans are for developers wanting to use Visual Studio 2026 for making add-ins? I suspect it may be for version 3.7 and beyond.

Just curious to know 🙂

Running Visual Studio 2026 v18.1 with ArcGIS Pro SDK 3.6 at the moment.
Haven't uninstalled 2022 yet though😁

VS 2026 will be supported at 3.7, the next release of Pro.

I'm only debugging pre-existing Add-In projects at the moment, that seems to work at least.

I had to report my findings, I had install 2026 on a new machine. I can report creating a new add-in seemed to work with the ArcGIS Pro 3.5 SDK along with debugging an existing one. However, I have had one annoyance where I'd get the error below every so often when rebuilding a solution. But a subsequent build works fine.

1> Failed to load the dll from [C:\Program Files\dotnet\host\fxr\10.0.3\hostfxr.dll], HRESULT: 0x800700C1
