About this project

Demonstrates how to use Redis Cache from a .NET Core Azure function app

Accompanying article

This code accompanies the aricle I wrote here https://medium.com/@saurabh.dasgupta1/about-7fb96fb1f80d

What does this SOLUTION contain?

Azure function (HTTP trigger)

• FunctionApp1.csproj
• This implements a few HTTP end points which interact with Redis

Some basic unit tests

• UnitTestProject1.csproj
• Less of unit testing and more to demonstrate various code snippets

Deployment

• PowerShell scripts for infrastructure deployment (App service plan, app, redis cache, app insight)
• ARM template

How to create the Azure resources and deploy your code?

• You will need an Azure subscription
• Ensure you have PowerShell and the Az modules installed
• Once installed ensure you have done a login from PowerShell via Connect-AzAccount
• If you run Get-AzSubscription then you should see teh subscriptions available to you
• Launch a PowerShell console and navigate to the Deployment project and run CreateAzureResources.ps1
• Wait for the script to complete. Deploying Redis Cache can take up to 30 minutes.
• Once done, you will now have to compile and upload your Function app binaries to the new App Service that you just created in the previous step
• Run the script UploadToAzure.ps1. You should run this script from a PowerShell console which is able to run dotnet cmdline exe

How to test the deployment succeeded?

Visual inspection

• You should see a new resource group rg-dev-redis-demo
• You can use Postman to fire the HTTP end points as shown below
