Visual Studio - Kill the existing process using the Azure Functions Port and attach to the running function at runtime

Question

My Scenario is:

I'm running one function locally which is using the port 7071 by VS 2022.

When I launch another function, it is saying that port 7071 is unavailable, using by another process.

I can define alternative port on local.settigns.json

But What I want to achieve here is, When I launch the another function locally in VS IDE, it should close/destroy the existing process using by the port 7071 and attach that port to current launching function in runtime?

Is this Possible, How.

Hi @Vaishnavi

Thanks for your patience. After investigating, I find a workaround.

I found that when a project uses port 7071, another project needs to be rebuilt or built before the following script can be executed. Sometimes we can run directly by clicking Run, but more often it is not. The reason may be that the current project has not changed, and VS2022 will not compile. Like the pre-build name in our workaround, the script will only be executed when the build needs to be executed.

Official doc : How to: Specify build events (C#)

My Test Result:

My .bat file

for /f "tokens=5" %%a in ('netstat -aon ^| findstr "7071"') do taskkill /f /pid %%a

exit 0

Settings in VS2022
