Add aspire component template #5239

Is there an existing issue for this?

Is your feature request related to a problem? Please describe the problem.

Currently there's distinction between external components and internal projects, in a microservice setting you most likely don't have all the services inside the same solution. A "component template" or "external project" would fill this gap where a service is being developed that others can connect and interact with.

Describe the solution you'd like

The template would be set up in such a way that it can be packaged for other services to depend on. Just like components, these services could be hosted locally or connect to a live instance.

Additional context

Note this is a rough idea perhaps there's a way to do this today but I think it's worth considering it as a first-class building block.

I think what could accompany this is a "aspire library template" as a centralized package that services could depend on. It would include the defaults and all the definition from internal and external components that underlying services in a cluster could use.

Let me know if I am interpreting this correctly: You want to be able to package up a project as an aspire resource and have other services on the team use it?

That's exactly correct. To elaborate, right now an aspire project would consist of the following:

Suppose ProjectA and ProjectB and optionally ServiceDefaults are developed separately, then the structured is factored into:

Solution1

Solution2

This way, ProjectA can use Hosting and Component packages from ProjectB while being a completely separate codebase.

It's important to be able to connect to a live instance (e.g. staging endpoint) as well as spinning up the image from hosting package.

Note Hosting and Component packages don't have to live close to the actual project and can be deployed separately.

Solution0 (shared packages)

Solution1

Solution2

The shared packages are already a common practice to avoid code duplication which I think aspire could encourage.
