Azure App Configuration – Central Configuration Repository

Cloud based applications are distributed in nature. As the times go it becomes more and more difficult to maintain an overview over all settings used across all of the components. Finally there is a new Azure service to store and manage application and deployment settings and feature flags in one place.

Use Managed Identity in Azure API Management to Authenticate With an Azure Function

You don’t want that someone is calling your Azure Functions unauthenticated. You can rely on old-school function keys or use Azure Active Directory. Azure Functions provide elegant Authentication / Authorization functionality previous known as Easy Auth which works nicely with Azure API Management.

Authenticate against Jira REST APIs with OAuth 1.0a 1-Legged and .NET Core 2.x

OAuth specification 2.0 is out there since 2012 but 1.0a version is still widely used. Atlassian’s Jira is for example such case. You wouldn’t find anything about 1-Legged OAuth in the documentation but the fact is, by now, Jira is still supporting this flow but referring to this wrongly as 2-Legged OAuth. Sadly there aren’t lot of .Net Core libraries which implements OAuth’s 1-Legged, as described in the The OAuth Bible. I implemented this functionality into oauth-dotnetcore and will show you how this can be used to access Jira APIs.

Publish Nuget Release and Prerelease Packages by Tfs Automated Build

There is good reason to create NuGet packages automated. This will eliminate the difficult and error-prone manual process. Creating and publishing of NuGet packages isn’t hard by the Team Foundation Server (TFS) build, except of prerelease versions.

What Did We Forget? Oh, State Machine.

Last week I evaluated couple of State Machines. It wasn’t some structural evaluation, rather quick overview what is today in the market. I was just about to have something lightweight and easy to use so I have looked into Appccelerate and Stateless from Nicolas Blumhard. As I went through my sample I asked myself: Why we don’t use State Machines frequently? I asked couple of colleagues if they do. They don’t. Do I? No.

Xamarin and Autofac: How DependencyService and Dependency Injection are working together

The Xamarin.Forms includes DependencyService to help shared code to resolve platform specific implementation. The important thing here is that DependencyService isn’t replace for Dependency Injection container. DependencyService is rather service locator than IoC container. I will show you how they can work together. Although I’m using Autofac as IoC, the proposed design and architecture should be applicable to any IoC Container.
