Research direction

Start at src/core/constants.ts around line 307, where the supported API language and version values are defined. Reproduce the deployment command from the issue or run the relevant CLI tests, then verify that a dotnetisolated v10 publish output is accepted without the reported language-info error.

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:

  1. Add NET 10 API as publish output (not source code) 'dotnet publish api.csproj -o ./api'
  2. 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
