Deploy single service in a monorepo Azure

Question

I'm working with azure devops, my project is a monorepo contain multiple services host in github.
Every time I make change(s) in one service, I have to build all the others (loop through all folders and build) then push it to fabric.
How can I config azure to build and push only changed project? Here is my solution folder structure

Microservices/  
    ├── Service A/
    ├── Service B/
    └── Service C/

Thanks

Unfortunately, there is no out of the box solution. A workaround is setting up multiple pipelines for Services and triggered by changes in each Service folder. For example:

Microservices/ 
    ├── azure-pipelines.yml 
    ├── Service A/
        |── azure-pipelines-a.yml
    ├── Service B/
        |── azure-pipelines-b.yml
    └── Service C/
        |── azure-pipelines-c.yml

And use the path filter to decide which yaml will be triggered. For example:

trigger:
  branches:
    include:
    - master
    - releases/*
  paths:
    include:
    - ServiceA/*

In addition, you can use Step templates for the steps used in multiple builds.
