1. Get to know our basic Angular TabsComponent (in master branch here)
2. Declare a template within a template using ng-template in Angular
3. Pass a reference of an ng-template to a component and render it in Angular
4. Pass data to be rendered in a dynamic ng-template using ngTemplateOutletContext in Angular
5. Define an anchor point where to render dynamic components in Angular
6. Dynamically instantiate an Angular component

I’ve started looking at using MediatR for my domain events implementations. To that end, I created a quick sample project using ASP.NET Core 2.0. Overall things were pretty easy to get going. If you haven’t used MediatR before, or if you’re looking for a quick intro on how to set it up for ASP.NET Core, keep reading (if not, how did you get here? Was the title not clear?). 

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. 

Summary

It’s pretty easy to differentiate use cases for Result and exceptions. Whenever the failure is something you expect and know how to deal with – catch it at the lowest level possible and convert into a Result instance. If you don’t know how to deal with it – let it propagate and interrupt the current business operation. Don’t catch exceptions you don’t know what to do about. 

This library helps write code in more functional way. To get to know more about the principles behind it, check out the Applying Functional Principles in C# Pluralsight course.

Input Validation for me is about validating the user input. Some people call "Name must not be empty" a business rule, I think about it as input validation. Business Rules validation is more complex, because a business rule for me is not "Name must not be empty", it is a definition of a state in the system that requires an action. Here is a definition of a business rule:
