App-Idea 2: Roman to Decimal

Another number conversion project (Roman-To-Decimal) takes numbers represented as roman numerals from input strings and converts them to their decimal value. Again, we will add the ability to convert back from decimals to roman numeral notation as well. This conversion project will use the same layout design as the Bin2Dec project. We will add this … Continue reading App-Idea 2: Roman to Decimal →

Lesson 1.6: Using Dependency Injection

In lesson 1.5, we discussed what dependency injection was and how to build two classes to integrate our DI engine into the Spectre.Console.Cli app. This lesson will build on that and show how we can use dependency injection in a more robust example. We will build a fully-functional IUniversityRepository, which implements all of the CRUD … Continue reading Lesson 1.6: Using Dependency Injection →

Lesson 1.5: Setting up Dependency Injection Components

Spectre.Console supports the ability to use dependency injection to find types for our commands. The library has an integration mechanism so that developers can use their favorite DI engine with their command-line app. In this lesson, we will learn how to integrate the .NET Extensions dependency injection engine with Spectre.Console. If you are unfamiliar with … Continue reading Lesson 1.5: Setting up Dependency Injection Components →

Lesson 2.5: Using Blazor Dependency Injection

Dependency injection (DI) is a software design pattern that removes hard-coded dependencies from an object and makes it possible to change those dependencies, whether at run-time or compile-time. This pattern can be used as a simple way to load plugins dynamically or to choose stubs/mock objects in test environments vs. real objects in production environments. … Continue reading Lesson 2.5: Using Blazor Dependency Injection →
