Describe the bug
A clear and concise description of what the bug is.
My function is build with net10, but went I set the api-version to 10.0 I get the following error
13-Jul-2026 18:46:46 | - Preparing deployment. Please wait...

13-Jul-2026 18:46:48 | ✖ Cannot deploy to the function app because Function language info isn't provided, use flags "--api-language" and "--api-version" or add a "platform.apiRuntime" property to your staticwebapp.config.json file, or create one in ./src.

To Reproduce
Steps to reproduce the behavior:
- Add NET 10 API as publish output (not source code) 'dotnet publish api.csproj -o ./api'
- Type in command 'npx @azure/static-web-apps-cli deploy ./src --env production --api-location ./api --api-language "dotnetisolated" --api-version "10.0" ...'
You get the error above
It should not give errors, as .net 10 was released last November.
If I change the version to 9.0, the deployment works fine, so probably api version is irrelevant?
The fix trivial: change the constants file

Hi Simone Chiaretta (@simonechGSC) , thank you for report. dotnetisolated v10 haven't supported by SWA platform, you can check https://learn.microsoft.com/en-us/azure/static-web-apps/languages-runtimes for supported languages and runtimes. Sorry for inconvenience.

Hey Jikun (@cjk7989), issue Azure/static-web-apps#1692 has open for this since .Net 10 came out. Microsoft doesn't even support .Net 3.1, .Net 6 and .Net 7 anymore and in less than 4 months .Net 8 and .Net 9 won't be supported either. The community could use some help on this one sooner rather than later.
