Getting started with YARP

YARP (Yet Another Reverse Proxy) is a versatile and highly performant reverse proxy library for .NET. If you’re a .NET developer seeking to develop a web application that utilises a reverse proxy to enable things like load balancing, caching and SSL termination, and you require a great degree of customisation, YARP is the ideal solution…

Communicating with ASP.NET Core hosted services from API endpoints using Channels

InAPIs Web

Hosted services are a powerful .NET feature, providing a robust mechanism for executing long-running background tasks in different types of applications. Given the flexible nature of .NET, such applications could be running on client devices, on-premise servers, or the cloud, depending on the particular use case. When it comes to ASP.NET Core, hosted services are…

ASP.NET Core runtime exception: Could not load type ‘Microsoft.IdentityModel.Json.JsonConvert’

InAPIs Web

When developing ASP.NET Core web applications, it is common to interact with JWTs (JSON Web Tokens). Quite often you will want to validate JWTs and possibly even generate your own JWTs to secure API endpoints. However, it’s not always plain sailing when it comes to software development. After updating certain Microsoft NuGet packages to newer…

Exploring ASP.NET Core Minimal APIs: Should I use them in production?

InAPIs

If you’ve been keeping up to date with what’s new in the .NET ecosystem over the last year or two, you’ll probably already be aware of the Minimal APIs feature that debuted in ASP.NET 6.0 back in 2021. However, since Minimal APIs are still a relatively new concept, perhaps you haven’t considered using them in…

Publishing your first C# Azure Function using Visual Studio

InAPIs Web

In my previous post, I introduced Azure Functions and walked through the process of creating and debugging your first C# function using Visual Studio. This time, I’m covering the topic of deployment and how functions can be published to Azure. After reading this article, you’ll understand how to publish an Azure Function to Azure using…

Creating your first C# Azure Function using Visual Studio

InAPIs Programming Web

Azure Functions is an Azure cloud service that allows software developers to focus on writing code that reacts to events, without needing to concern themselves as much with the infrastructure that the code is running on. Azure Functions applications are serverless by nature and can scale to meet demand with minimal overhead and cost. There…

Implementing the Request-Response pattern using C# with JSON-RPC and WebSockets

InAPIs Programming

The Request-Response pattern seems somewhat simple on the surface; send a request, then wait for and receive a response that matches up with the original request. However, implementing this pattern in an efficient manner is something that is easy to get wrong. I’ve found that much of the material online regarding this topic tends to…

Diving into curl as an API developer

InAPIs Scripting

If you’ve been a developer for some time now, chances are you’ve heard of ‘curl’. Maybe you’ve stumbled across a reference to it on an API documentation page, then copied and pasted a command and thought nothing more of it. Many times I find that tools like curl have a lot of hidden powers that…

Protecting access to gRPC services with Auth0

InAPIs

Having already introduced the concept of gRPC services and having walked through how to consume a gRPC service using .NET Core, I’m now going to cover the next most fundamental topics; authentication and authorization. For production applications, your API endpoints are normally going to be available publicly and therefore they need to be protected from…

How to consume a gRPC service using .NET Core

InAPIs

In a prior post, I introduced the key concepts behind using gRPC to develop an RPC service and walked through the process of creating a sample project. In this article, I build on the previously discussed topics by adding an additional service and a client to the sample project. After reading through the content below,…
