Implement Roles With Keycloak, Web API and Blazor WebAssembly (RBA)

Marinko Spasojević — Fri, 21 Feb 2025 07:20:52 +0000

In this article, we will take a step further from the previous one by implementing role-based authorization with Keycloak, Blazor WebAssembly, and Web API. If you haven’t read the previous one, I strongly recommend doing that to gain a full picture of the authentication implementation. By assigning roles to users in Keycloak, we can control […]

Keycloak Authentication With ASP.NET Core Web API and Blazor WebAssembly

Marinko Spasojević — Mon, 17 Feb 2025 07:59:06 +0000

In this article, we are going to learn about integrating Keycloak authentication in a Blazor WebAssembly (WASM) frontend and a .NET Web API backend. With this setup, we will enable secure user authentication across both applications. Keycloak is an open-source identity and access management solution that provides authentication, authorization, and user management out of the […]

Hybrid Caching in ASP.NET Core

Bozo Spoljaric — Mon, 10 Feb 2025 07:02:05 +0000

In this article, we’ll introduce hybrid caching in .NET, a new cache type that bridges the existing cache mechanisms in .NET: distributed cache and memory cache. We’ll start by briefly explaining a cache and how existing caches in .NET work. After that, we’ll explore hybrid caching and show how it can be used and configured […]

Testing Database Connectivity with EF Core

Georgi Georgiev — Thu, 23 Jan 2025 11:08:23 +0000

Whether during application startup, multi-step workflows, or monitoring an application’s overall health, verifying database connectivity is essential for smooth operation and graceful handling of potential failures. It improves reliability and the overall user experience. In modern containerized environments, often managed by orchestrators like Kubernetes (K8S), it’s equally important for services to report their health status. […]

Persist Values With AsyncLocal in C# Async Flow

Bozo Spoljaric — Mon, 06 Jan 2025 05:55:32 +0000

In this article, we’ll explain the AsyncLocal class and how to persist values across an async flow with the AsyncLocal class in C#. We’ll start by describing the challenge that AsyncLocal solves and continue with examples of how it does that. We’ll scratch the surface of the AsyncLocal inner workings and finish with the cases […]

Comparison of Rebus, NServiceBus, and MassTransit in .NET

Michal Kaminski — Mon, 16 Dec 2024 04:28:02 +0000

Messaging systems are the backbone of scalable and distributed applications in .NET. They allow different parts of an application, or even separate applications, to communicate efficiently and reliably. Choosing the right messaging library, Rebus, NServiceBus, or MassTransit, is essential to ensure our system’s performance and long-term maintainability. In this article, we will compare Rebus, NServiceBus, […]
