Course Overview
The Dapper in .NET course by Microsoft is designed for .NET developers, software engineers, and backend developers seeking to master high-performance data access in modern applications. This course covers Dapper, a lightweight micro-ORM that extends ADO.NET with efficient object-relational mapping, enabling developers to write fast, clean, and maintainable data access code. While no specific certification exam is directly tied to Dapper, this training supports broader Microsoft .NET and Azure certification paths such as Exam AZ-204: Developing Solutions for Microsoft Azure. With 89% of Fortune 500 companies actively seeking .NET developers proficient in performance-optimized data access, mastering Dapper addresses a critical industry need for scalable, high-throughput applications.
Students will work with core technologies including .NET 8, SQL Server, Azure SQL Database, Dapper ORM, and the Elastic Database Client Library, using Visual Studio and Azure Portal for development and deployment. The hands-on labs focus on real-world implementation, where students build a scalable multi-tenant application using sharding and data-dependent routing. In the lab environment, learners configure database connections via OpenConnectionForKey, execute CRUD operations using Dapper’s Query and Execute methods, and integrate Dapper with Azure SQL to manage distributed data efficiently. A key project involves building a tenant-aware REST API that routes queries to the correct database shard, demonstrating performance optimization and consistency in cloud-scale applications.
This course prepares developers for Microsoft Applied Skills credentials in Azure development and enhances career readiness for roles such as Senior .NET Developer and Cloud-Native Software Engineer. According to 2026 market data, professionals with Dapper and .NET expertise earn median salaries of $155,000–$200,000 in the United States, with strong demand in enterprise and SaaS environments. Koenig Solutions differentiates itself with Guaranteed-to-Run batches, 1-on-1 mentoring, and official Microsoft courseware, ensuring hands-on mastery. Completing this training positions developers to lead high-impact projects in cloud-native, data-intensive applications, driving innovation in modern software architectures.
