.NET Aspire integrations offer a model and sets of packages that make it straightforward to host and consume many types of resources in your systems. Integrations typically provide resources similar to the offerings of cloud platforms for a variety of services, including databases, storage, message queues, and much more. They are typically structured as a pair of NuGet packages, one for hosting the resource in your system and one for consuming it. Microsoft publishes many such integrations and there are others that are community supported. You can also make your own if you have a need.
