.NET, Dapr and Aspire

As a .NET developer, you will have either built distributed apps or heard about them. Distributed apps, microservice or not, come with a new set of complexities that you previously didn’t have to deal with. However, those complexities are easily embraced by setting up a good local development environment.

This is where Dapr and .NET Aspire come in. We will see and run a demo app that demonstrates how to set up your local development environment and get started using these technologies.

With the launch of .NET 9, many interesting changes have been introduced that affect how .NET Aspire and ASP.NET Core work. We will explore them and see how they improve our code and daily work.

Expect a session full of code, containers and telemetry!
