Multiple Azure Functions Core Tools versions

I have both version v3 and v4 installed of Azure Functions Core Tools on windows.

How do I start a function using a specific version of Azure Functions Core Tools?

When I do like this:

c:\code> func start

That will start v3.

I can get it to use v4 using hardcoded path:

c:\code> c:\Users\xxx\AppData\Local\AzureFunctionsTools\Releases\4.10.1\cli_x64\func.exe start

But how do I prevent using path that will change from version to version?

Solution

  • Glad that your issue got resolved based on my comments I am converting that as an answer to help the other community members who face similar kind of issues.

    • You can only install one version of core tools on a given computer as stated in Microsoft documentation.
    • When you check the version of azure function core tools, it will show the version you have installed recently.
    • After installing new version of core tools to run the old version project,
      • Either you have to update the azure functions core tools package version inside the project (or)
      • Downgrade/Upgrade your azure functions core tools version according to your requirement and compatibility in your local environment.
