When the class creates a dependency using a concrete class , this brings the dependency wholesale into any tests you write, as test doubles (such as mocks) can’t be created to represent their behaviour. 

The Intersection of Microservices, Domain-Driven Design and Entity Framework Core
Domain-Driven Design (DDD) provides much of the strategic design guidance that we can use to determine the boundaries around and interactions between Microservices in our solutions. DDD also follows up with tactical design patterns for your business logic. In this session we'll take a look at some of these patterns and how EF Core naturally, or with some additional configuration, persists the data that your microservices depend on. 

New Breaking Changes

Angular now compiles with Ivy by default. See Ivy compatibility section.

Typescript 3.4 and 3.5 are no longer supported. Please update to Typescript 3.6.

tslib is now listed as a peer dependency rather than a direct dependency. Users not using the CLI will need to manually install tslib via yarn add tslib or npm install tslib --save. 

Blazor United prototype
A quick look at some of the experiments we're considering for Blazor in .NET 8 

In this post I look at the various different version numbers you can set for a .NET Core project, such as Version, VersionSuffix, and PackageVersion. For each one I'll describe the format it can take, provide some examples, and what it's for. 

Learn Minimal APIs in .NET 7

in this tutorial you will lean how to create a an awesome popup gallery. Each gallery will have a small preview animation. This tutorial will provide you with five different popup galleries. All the main animations are done using CSS transitions. I would of liked to build the entire thing using CSS only but unfortunately this was a pretty complex gallery so i had to use some JavaScript.  Demo
