Azure Functions Mac - Wrong Host Version

Question

I am trying to debug an Azure functions project on my Mac using Visual Studio Mac.

I have updated my core tools to version 2.0.3. If I type func at my terminal, I can see I updated to the latest version.

Azure Functions Core Tools (2.0.3)
Function Runtime Version: 2.0.12115.0

You can also see the runtime version is 2.0.12115.0.

However when I debug using Visual Studio Mac, I get a runtime error:

Hosting environment: Production Now listening on: http://0.0.0.0:7071 Application started. Press Ctrl+C to shut down.

Notice the runtime version is Version=2.0.11933.0.

There must be a way to tell visual studio where the location of the Azure-Functions-Core tools is installed or can I at least copy my 2.0.3 installation to where Visual Studio is executing from, where ever that is.

Visual Studio for Mac currently needs to be updated for every Functions CLI release. It unfortunately does not support being configured with a version of the Functions CLI installed on the machine (and this has been problematic for a lot of people).

The next VS Mac update should reference the latest Functions CLI and I believe an update is planned to allow it to independently update the version of the CLI it uses without requiring a full VS update.
