Migrating to ASP.NET Core

In the quest to migrate to .NET Core, the first step at the time (a couple of years ago) was to start migrating to ASP.NET Core from using Katana (Owin). This seemed like a logical first step as ASP.NET Core 2.x could run on .NET Framework as well as .NET Core. Ultimately this was a good first step in our migration. ASP.NET Core 3.x is only supported on .NET Core 3.0 because it targets netstandard2.1. .NET Framework only supports netstandard2.0 and will never support netstandard2.1 This makes it much more challenging to migrate because my recommendation is to get your… Read More »Migrating to ASP.NET Core

Roundup #70: Coyote, DetectDuplicates, YARP, .NET 5, Lambda?

Coyote: Making it easier for developers to build reliable asynchronous software For developers, writing bug-free software that doesn’t crash is getting difficult in an increasingly competitive world where software needs to ship before it becomes obsolete. This challenge is especially apparent with online cloud services, which are often dictated by aggressive shipping deadlines. Cloud services are distributed programs comprising multiple back-end systems that continuously exchange asynchronous signals while responding to incoming web requests. They are complex by nature, hard to get right, and require protection from failures that could jeopardize client data or halt key services.

Migrating from .NET Framework to .NET Core

Over the course of several years, I’ve been slowly migrating a 5-year-old system built on top of .NET Framework (v4.8). In this blog series, I’m going to describe each step of the migration, as there were many, in order to get the system running entirely on .NET Core. This is series intended as a guide for Migrating from .NET Framework to .NET Core. This wasn’t a “big bag” migration, but rather a series of steps that were taking over the course of years. That’s not to say your migration will take as long. System Background In order to get a… Read More »Migrating from .NET Framework to .NET Core
