Hello!

Thanks heaps for a lot of great feedback on the latest changes. It looks like the newsletter is heading into the right direction. Please keep it coming and I'll try to improve every week.

How fast is really ASP.NET Core?

In recent years the .NET Team has been heavily advertising ASP.NET Core as one of the fastest web frameworks on the market. The source of those claims has always been the TechEmpower Framework Benchmarks.

Going Beyond .NET Core Identity Authentication with OIDC (sponsor)

Using ASP.NET Core Identity is great for demos but leads to pain down the road as you grow. This article and example illustrates how to use ASP.NET Core’s OpenID Connector to centralize your .NET app’s authentication and authorization with an OIDC compliant identity server. Your user data will be more secure and you’ll sleep better at night.

OpenTelemetry, The Missing Ingredient

At its core, OpenTelemetry (OTel) is a vendor-neutral standard for telemetry. But it also provides a complete end-to-end implementation for generating, emitting, collecting, processing and exporting telemetry data to any support observability back-end.

7 Reasons for Startups to Choose ASP.NET Over Node.js

Node.js is probably the most popular backend technology in the industry. Companies like Twitter, LinkedIn, Uber, and many others use Node.js as their primary server technology or combine it with other languages. It has a lot of things going for it like a huge community, a great ecosystem, and it uses the same language in the front end and back end. Since C# and .NET are my main programming languages, I’m trying to figure out if I’m using an underrated technology or if the market trend has a point.

And we'll wrap up with a few short links.
