Dependency Injection in Minimal APIs in C#

Minimal APIs are an increasingly common way to create small API projects including microservices. But how do you handle dependency injection with a Minimal API? It turns out the answer to that is rather simple. In this video, I will show you how to use dependency inject, route parameters, and more in 10 minutes or less.

Thanks for the great video Tim!
It would be great if you could also reference your previous video links for things which are seen in this video, e.g. using Http files in VS, so that people which see those things for the first time can catch-up quickly.

Hey Tim I really like your content and have learned a lot. I think you should consider giving a more “production” or “large-scale” scenario with videos. I often find the basics are usually straightforward but then seeing how it could be used in a large scale app could be useful as well

[pavfrang]

As always clear and precise! The simple examples are the root for better understanding, thanks!

Excelente video, esa forma de enseñar tuya es muy fácil de entender. Llevo dos meses siguiéndote y vale mucho la pena tu información.

Thanks for the great video. In MVC there's the [FromServices] attribute that we apply to function parameters for this sort of thing. I take it that idea didn't map over to Minimal APIs too well.

Great video, short and concise.
How would I go about registering my own services, e. g. for Data Access? Where would I put that inside of program.cs?

[torrvic]

Looks very unusual. Interesting…Thanks for sharing!

[BobbyBridgeman]

A little off topic, but when was the 'with' keyword implemented in c#? First time I have come across it!

[shahzadazzam]

Thank you for the short and great video :)

None of this is dependency injection? No service registration. No lifetimes. No container setup at all. This is just getting config values, and you didn’t even show object binding which would have been simpler than the “:” notation.

Great! But how this works under the hood? I mean passing values from DI-container to lamda parameters of mapping methods?

What if you dont want to pass in a config inut parameter every single time your create an endpoint? Isn't it bad code to repeat the same thing again and again and again?

Is there any relevance in the real world for minimal api? I am a seasoned software developer and I haven’t seen this being used. I’m not bashing rather trying to understand the usefulness and adoption status of this technology

[tinylittleanj]

what is an actual real world use case for this?

[pxnchx]

So stuff from the appsettings json is the only thing we can inject in this kind of APIs?

Need to calm that mouse down. Super distracting seeing the cursor draw circles all over the place.
