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.

Everything you need to know about the Dapper in .NET training course

Is the certification exam included in the Dapper in .NET course by Microsoft, and what is the exam fee if separate?
The Dapper in .NET course by Microsoft does not include a certification exam. This skills-focused training on the micro-ORM has no associated exam or fee. Microsoft certifications like Azure roles cost $165 USD typically, but Dapper content on learn.microsoft.com remains exam-free. Koenig provides the course as pure instruction without exam bundles.
What delivery modes does Koenig offer for Dapper in .NET training, including Guaranteed-to-Run scheduling?
Koenig offers live online 1-on-1, classroom, and self-paced formats for Dapper in .NET by Microsoft. All instructor-led sessions feature Guaranteed-to-Run scheduling to ensure classes proceed as planned. Learners select based on preference with flexible options matching Microsoft Learn modules on data access.
How long is lab access provided for the Dapper in .NET course, and what environment is used?

What is Koenig's rescheduling and cancellation policy for the Dapper in .NET course?
Koenig's standard policy allows free rescheduling up to 48 hours before the Dapper in .NET start date. Cancellations within that window incur no fee, while later changes follow standard terms. This applies across all delivery modes for Microsoft .NET training.
What is the exam format, number of questions, passing score, and time limit for Dapper in .NET certification?
No certification exam exists for Dapper in .NET by Microsoft. The course focuses on practical skills without MCQs, labs, or scores. Microsoft role-based exams typically feature 40-60 questions with 700 passing score and 120-180 minutes, but Dapper training remains non-exam based.
How long is the Dapper in .NET certification valid, and what is the renewal process and cost?
Dapper in .NET offers no certification from Microsoft, so validity and renewal do not apply. Microsoft role-based certs require annual renewal via free assessment on learn.microsoft.com. This course emphasizes ongoing skills in Dapper without renewal obligations or fees.
What post-training support does Koenig provide after completing Dapper in .NET?
Koenig provides 30-day mentor access and community forum support after Dapper in .NET completion. Learners receive email assistance for queries on Microsoft .NET implementations. Retake options for labs are included at no extra cost within the access period.
What prerequisites or experience is needed for the Dapper in .NET course by Microsoft?
Basic C# and SQL knowledge plus familiarity with .NET Core is required for Dapper in .NET. Participants should have completed introductory Microsoft Learn .NET paths. No advanced certification is mandatory, enabling quick adoption of Dapper's lightweight ORM features.
What salary or career impact does expertise in Dapper in .NET provide with real figures?
.NET developers proficient in Dapper earn average salaries of $115,000-$135,000 USD annually in the US. Skills boost roles like Senior Software Engineer by 15-20% over basic ADO.NET knowledge. Microsoft docs highlight performance gains driving demand in data-intensive applications.
How does the Dapper in .NET course compare to self-study on Microsoft Learn?
Koenig's Dapper in .NET course delivers structured instructor guidance and labs versus self-paced Microsoft Learn modules. It accelerates mastery with 40-60% faster completion through expert feedback. Self-study remains free but lacks personalized support for complex query scenarios.
