Create a protected .NET Core 3.1 API that calls into MS Graph on behalf of a Power App

In this blog post I'm going to explain how to create a .NET Core API that accepts authenticated requests from a Power App, validates the user and then makes a call into MS Graph to retrieve the appropriate data. All secured via Azure AD while using the latest (and funkiest) Microsoft.Identity.Web library for authentication and the MS Graph SDK for getting the Graph ┬ádata. If you haven't used the Microsoft.Identity.Web NuGet package yet, ┬áthen I would urge you to have a look at the repo and start integrating it with your ASP.NET Core apps. The …[read more]

Create a .NET Core Deamon app that calls MSGraph with a certificate

A couple of days ago I blogged about pulling OneDrive data with MS Graph in .NET Core. I wrote all the code in a console app because it was the simplest way to get me what I needed. Mind you, a console app is not the best way when it comes to creating user interactive apps but it's convenient. However, convenience comes with a price: I ended up writing a console app that needs user interaction for authenticating the app. So what is the right way to do this? How can we create a headless app/daemon that can still …[read more]

Accelerating MS Graph development with the new toolkit

I love trying shinny, new things, especially if it means that they can make my, and hopefully your, life easier. The MS Graph toolkit has been in GA since Sept 2019 so technically it's not really new, but since I'm new to MS Graph I decided to take it for a spin and see what it would take to get a simple html page to display some data from my test Azure AD tenant. If you are a developer and want an Azure AD tenant to experiment with, check out my previous blog where I show you how to get …[read more]

Call MS Graph APIs from ASP.NET Core 3.1

As I spend more time in my role as a PM for Microsoft Identity, the more I realize there is a whole world I don't know about. And as many of the developers out there, I make sure I spend as much time as I can learning new things. Today's learning? Integrating MS Graph into an existing ASP.NET Core 3.1 app. It may sound straightforward, but getting it to work proved a little bit more challenging because our developer story is so new. In addition, I wanted to experience what it would take to add MS Graph to …[read more]

Enumerate Azure Storage File Share files with the .NET Azure SDK

This is a quick one. I recently had to enumerate an Azure Storage File Share with unknown files and directories so I quickly put together this .NET Core Console solution using the latest .NET Azure SDK. You can find more info on the latest and coolest Azure SDKs here. Kudos to Jon Gallant (Azure SDKs team) for pointing me to the right/latest Azure SDK. It made my life so much easier and the code is more than half than the previous version. Start by creating a new console app and adding the Azure.Storage.Files.Shares NuGet package. Open …[read more]

Secure app development with Azure AD, Key Vault and Managed Identities

Developing applications using security best practices doesn't have to be hard. And yet, many organizations and developers struggle with this since the space is so vast and it's hard to know where to start. However, if you are developing that leverage Azure, then there are some powerful features in place to ensure that you and your team can develop secure code end to end. And for me, it's this end-to-end scenario that is done so beautifully, elegantly and effortlessly using the tools and services that you most likely already use on a daily basis. This scenario gets even stronger if …[read more]
