Course Overview

The Microsoft ASP.NET Core 3.1 Blazor course is designed for developers seeking to build modern, interactive web applications using C# and .NET. While there is no standalone certification exam specifically for Blazor, this training aligns with core competencies tested in Microsoft’s broader developer certifications, including the Microsoft Certified: Azure Developer Associate (AZ-204). It is ideal for roles such as Full-Stack .NET Developer, Web Application Developer, and Cloud-Integrated Frontend Engineer. With over 80% of Fortune 500 companies leveraging .NET for enterprise applications, demand for Blazor skills remains strong, particularly in industries modernizing legacy systems with component-based, single-page application (SPA) frameworks.

This course focuses on hands-on development using core Microsoft technologies including ASP.NET Core 3.1, Blazor Server, Razor Components, HttpClient, IHttpClientFactory, and Visual Studio Code. Students work directly in a local development environment to build functional web apps that consume RESTful APIs, such as a task-tracking dashboard or a Connect Four game, as featured in Microsoft Learn modules. Through structured labs, learners implement HTTP operations, integrate C# with Razor syntax, and render dynamic data using Blazor components—skills directly transferable to real-world projects. The training emphasizes practical implementation, such as using the Component Tag Helper to embed Razor components in MVC views and managing state during initial server-side rendering.

By mastering ASP.NET Core 3.1 Blazor, students prepare for roles in high-growth areas like enterprise web development and cloud-native applications, where .NET developers command average salaries between $85,000 and $135,000 annually. This course leverages official Microsoft Learn content, ensuring alignment with industry standards and real-world applicability. As a Koenig Solutions differentiator, this training is offered as a Guaranteed-to-Run session with the option for 1-on-1 delivery, enabling personalized pacing and deeper mastery. Upon completion, developers are equipped to create seamless, interactive web experiences without relying on JavaScript, positioning them for advancement into senior developer or full-stack architect roles.
