Our Verdict

This Udemy Master Class on gRPC with C# provides an in-depth exploration of a modern HTTP/2 API for .NET microservices. With 4 total hours of instruction, students benefit from a mix of theory and practical implementation exercises that touch upon bi-directional streaming, advanced security features, and CRUD operations. Although some examples showcase older .NET Framework versions or lack real-world recommendations, the course is still valuable for developers who wish to refine their skills using gRPC with C#.

What We Liked

Excellent overview of gRPC with C#, clear distinction between theory and implementation.
Detailed step-by-step instructions for building a fast scalable API.
Hands-on exercises for practicing gRPC concepts, including error handling, deadlines, SSL security, and CRUD operations over MongoDB.
Comprehensive exploration of unary, server streaming, client streaming, and bi-directional streaming scenarios.
Instructors Stephane and Clement provide unique insights to help deepen understanding.

Potential Drawbacks

Code examples are outdated—some may not work with newer .NET versions; consider Entity Framework or SQLite as alternatives to MongoDB for CRUD.
Lack of real-world architecture—missing best practices on sharing proto files and load balancing.
Some compiler warnings were overlooked, creating confusion around proper implementation.
Repetitive boilerplate code in sections 6-8; SSL section misses essential details.
The title is slightly misleading as some course content covers basic gRPC concepts.
