Introducing the .NET Hot Reload experience for editing code at runtime

Today, we are excited to introduce you to the availability of the .NET Hot Reload experience in Visual Studio 2019 version 16.11 (Preview 1) and through the dotnet watch command-line tooling in .NET 6 (Preview 4). In the rest of this blog post, we’d like this opportunity to walk you through what is .NET Hot Reload, how you can get started using this feature, what our vision is for future planned improvements and clarity on what type of edits and languages are currently supported.

Highly COHESIVE software design to tame complexity

What is cohesion and why should you care? Highly cohesive software design can reduce complexity and coupling. But what is cohesion? It’s the degree to which the elements inside a module belong together. How you group operations together can have a widely different outcome on Cohesion. Informational Cohesion is grouped by operations on data. Functional Cohesion is grouped by operations of a task. It’s directly related to the Single Responsibility Principle, which you might also have a different definition of.

Pitfalls of unoptimized NuGet packages

You might unknowingly be using an unoptimized dependency which could impact the performance of your app.

Using DateOnly and TimeOnly in .NET 6

In .NET 6 (preview 4), two long-awaited types have been introduced as part of the core library. DateOnly and TimeOnly allow developers to represent either the date or time portion of a DateTime. These two new types are structs (value types) and may be used when your code deals with date or time concepts independently. Both types can be found in the System namespace.

Authorization in ASP.NET Core

In this first post, I’ll demonstrate how can we use a middleware to build a ClaimsIdentity which contains all the permissions of the logged-in user. This is the foundation for the next posts where we will use the permissions to authorize the endpoints. I’ll also talk a bit about JWT tokens and if it’s a good idea to include authorization-related claims in them.


RestClient.Net 5 Released

RestClient.Net makes HTTP calls in .NET easy. Send the request body as a strongly typed object, and get back a strongly typed object. You can inject the abstraction into your service classes and quickly mock them without worrying about the HTTP plumbing or converting to JSON.
