Tidy up - Unused Project and Nuget package reference using Visual Studio 2019

If you are a Developer/Architect using Visual Studio as IDE for your development activities, this blog post will be of your interest. During the Ignite 2021 conference, Microsoft released Visual Studio 2019 v16.9 and v16.10 Preview 1. As part of version 16.10 Preview 1, one of the cool features they introduced is to "Remove Unused References..." for any Projects and Nuget packages that are not in use. At the time of writing this blog post, we have Visual Studio Version 16.10.0 (official release) which includes this new feature.  As part of development, we generally get carried away and introduce new Nuget package references to your project and add new references to your Projects. By the end of development, you will not be 100% sure which are not being referenced and unused which means you will leave those unused project references in your application. Now you might be wondering what's the big deal in it since it doesn't harm. The advantage of removing unused project r

Disable Azure function for v1 and v2


Disabling an Azure function has a bug in v1, which is fixed in v2. Below I have made an attempt to explain with both version how it works.

Azure function v2

Enable or disable Azure function bug is fixed in Azure Function v2. Now things are driven through portal using the below setting




Azure function v1

Recently we had an issue in Production application, due to business reason we had to stop one of the Azure functions.

We used Azure function app service running on App service plan and function is Time triggered.

We tried with option available in Azure portal under functions where it lists all the functions available in the App service plan with status as shown below. For the Azure function we wanted to stop, we chose Disable option.


However, immediately we noticed that the function was still running, and the function monitor showed those further executions.

Solution:

Below are the 3 options

Approach 1:
Requires code change where we need to add “Disable” attribute and requires code to be redeployed.
Approach 2: 
Preferred option while developing Azure function needs to be considered.
This method lets you enable and disable the function by changing the app setting, without recompiling or redeploying. Changing an app setting causes the function app to restart, so the disabled state change is recognized immediately.



Approach 3:
If approach 2 is not considered during implementation at the same time don’t want to do a deployment to Production a work around option will be to rename the dll name from the Azure portal. No release required with this option.

Swagger UI for Azure Function v2 & v3 APIs

Image
In this blog post, we will see how to setup Swagger UI for Azure Function APIs in v2 and v3. Now you might be wondering why Swagger? Swagger is a language-agnostic specification for describing REST APIs, it also referred to as OpenAPI. Swagger UI offers a web-based UI that provides information about your REST APIs service. Prerequisites HTTP trigger Azure function provisioned or created in C# Azure DI enabled on Azure Function, for more details refer here  with relevant package version installed based on Azure Function version. Integrating Swagger UI into our Applications 1. Install the appropriate package based on the Azure Function version which you are dealing with from the below table. Unfortunately, it's not a single package for both versions due to Azure function v3 because v3 makes use of ASP.NET Core 3.1 which introduces a new serializer System.Text.Json (STJ) out-of-the-box.  Azure Function Version  Nuget package  v2               AzureFunctions.Extensions.Swashbuckle  v3

Authenticate Azure Functions - API Keys

Image
In this blog post, we will see one of the ways to secure your Azure Functions using API keys. Security plays a key role as part of SDLC (Software Development Life Cycle) doesn't matter whether it's exposed to the client/public or even if it's internal. There are multiple ways to secure your Azure Functions like API Keys, Certificate,  API Mgmt, App Service Authentication, etc. If you are new to the Cloud and Azure Functions but want to make a start with minimal effort and less setup of Infrastructure, then API Keys is the ideal choice. Azure Functions allows you to secure HTTP-triggered functions by API access key in the request. As part of creating new Azure Functions, we can select the Authorization Level enum value. If we set the Authorisation level to  Anonymous,  no security applied which means no authentication applied for the endpoint. Authorization Level - Function By setting the Authorisation level to Function each Azure Functions require a specific API key to Auth
