Task 9: Initialize the main branch (if it doesn't exist) and create a pull request-triggered pipeline for .
NET Core build
Step 1: Initialize the main Branch
* In your Azure DevOps Project (Project1), navigate to Repos .
* In the left menu, click Files .
* If you see a message like "This repository is empty," click Initialize .
* Create a README.md file (or another file) and set the default branch name to main.
* Click Initialize .
If the main branch already exists, you can skip this step.
Step 2: Create a New Branch for the Pipeline
* In Repos > Files , click on the Branches tab.
* Click New branch .
* Enter:
* Branch name: azure-pipelinesT
* Based on: main
* Click Create .
This creates a new branch named azure-pipelinesT from main.
Step 3: Create the Pipeline YAML File in the New Branch
* Switch to the azure-pipelinesT branch.
* In Files , click New file .
* Name the file: azure-pipelines.yml.
Step 4: Write the YAML Pipeline for .NET Core Build
Here's a sample YAML file:
trigger: none
pr:
branches:
include:
- main
pool:
vmImage: ' windows-latest '
variables:
buildConfiguration: ' Release '
steps:
- task: UseDotNet@2
displayName: ' Install .NET Core SDK '
inputs:
packageType: ' sdk '
version: ' 8.x ' # Or specify the exact version of .NET Core SDK you need installationPath: $(Agent.ToolsDirectory)/dotnet
- script: dotnet build src --configuration $(buildConfiguration)
displayName: ' Build .NET Core project '
This pipeline:
* Runs only when a pull request is created or updated targeting the main branch.
* Uses the windows-latest agent.
* Installs the .NET SDK and builds the project in the src directory.
Step 5: Commit the Pipeline File
* In the bottom commit message box:
* Message: Add PR-triggered pipeline for .NET Core build
* Ensure the branch is set to azure-pipelinesT .
* Click Commit .
Step 6: Create the Pipeline in Azure DevOps
* In the left menu, click Pipelines .
* Click New pipeline .
* Select:
* Azure Repos Git .
* Select your repository.
* Choose Existing Azure Pipelines YAML file .
* In the branch selector, choose the azure-pipelinesT branch.
* Select the YAML file path (azure-pipelines.yml).
* Click Continue and Run to validate.
Step 7: Test the Pipeline Trigger
* Create a new branch (e.g., feature/test-pr).
* Push a commit and create a pull request targeting main.
* Verify that the pipeline runs automatically for this PR in Pipelines .

The Custom ScriptExtension downloads and executes scripts on Azure virtual machines. This extension is useful for post deployment configuration, software installation, or any other configuration or management tasks. Scripts can be downloaded from Azure storage or GitHub, or provided to the Azure portal at extension run time. The Custom Script Extension integrates with Azure Resource Manager templates, and can be run using the Azure CLI, PowerShell, Azure portal, or the Azure Virtual Machine REST API.
