.NET Aspire

.NET Aspire is an opinionated, cloud ready stack for building observable, production ready, distributed applications. .NET Aspire is delivered through a collection of NuGet packages that handle specific cloud-native concerns. Cloud-native apps often consist of small, interconnected pieces or microservices rather than a single, monolithic code base. Cloud-native apps generally consume a large number of services, such as databases, messaging and caching.
