This course, Build Distributed Apps with .NET Aspire, equips developers with the knowledge and tools to create robust cloud-native distributed applications. Through hands-on labs and practical scenarios, learners will explore .NET Aspire's integration capabilities, telemetry tools, database interactions, caching strategies, and message brokering with RabbitMQ. By leveraging Visual Studio and the .NET Aspire stack, participants will enhance application performance, scalability, and maintainability.

This course is for Cloud Architects and Developers.

Students should have experience building web applications using .NET and C#

After completing this course, students will be able to:

• Learn how .NET Aspire supports cloud-native distributed app development.
• Implement .NET Aspire integrations for functional application needs. Build and troubleshoot .NET Aspire projects using Visual Studio.
• Monitor app performance with OpenTelemetry and .NET Aspire telemetry tools.
• Connect and use databases like PostgreSQL, MySQL, SQL Server, and MongoDB.
• Boost performance with Redis caching in .NET Aspire applications.
• Enable microservice communication using RabbitMQ message brokering.
