gRPC Service with .NET 7

In this video we build a gRPC service with 5 methods: Create, Read (single), List (multiple), Update and Delete. We then employ JSON transcoding (a new feature added in .NET 7) to allow our gRPC service to act as a REST based API. This allows web-based endpoints to consume our service, while at the same time continuing to allow native gRPC clients to consume as well.

Welcome back Les, and thank you for your efforts

[highfive]

I love how you make advanced topics seem easy plus I love your accent.

[eugene-dmitrievich]

Thank you so much for this video! Interesting explanation of gRPC, Protobuf, .NET, JSON transcoding

[mohammadramezani]

Welcom back les can we use grpc in angular in dotnet7?

[pavankumard]

Good video, I wish there was an example to show how two microservices could communicate with eachother using Protobuf

[kunalkslvlogs]

I love your content and regularly watching your videos

Hey Les, this was absolutely fantastic and I learned a ton. I wasn't able to get .Net 7 to work for me because HTTP/2 isn't fully supported on macOS. However, I was able to use .Net 8 Preview on macOS because HTTP/2 is fully supported. Thus, I was able to code along without changes. The JSON transcoding is super awesome and it was very easy to setup. I'll definitely be leveraging this in my projects. Bravo!!!! 🙌🏾👏🏾👍🏾🔥

Thank you for this. very nice explanations as always.

Love this video. I've had an eye on gRPC for some time now, so it's great to see how easy an implementation could be.

The note about using mapping frameworks like AutoMapper brought me back to old debates on my team. We have a number of large and relatively complex objects in our services with a lot of attached metadata, and we used to use AutoMapper to handle the mapping so we didn't need to write these large mappers by hand. We eventually moved away from those to manual mappers for a couple of reasons: trying to debug errors in AutoMapper was way harder than it needed to be, so when something went wrong the reasons why were hidden away and not easily discernible from the stack trace, and also because they were several times more performant than AutoMapper. Would love to know your thoughts on that

Waiting for new videos!!! This is high quality content.

[FabioOno-es]

Awesome explanation... Thank you Les 👏👏👏

[vineetkumarsingh]

Great video Les, loved your content. I would have loved to see you using another c# application as client, rather than using postman. That would have completed the loop.

[avanthasiriwardana]

If Les, no comments. Always good stuffs, Thanks Mate

[ahmedsalah-rgvj]

Does gRPC is good for gust service to service communication or it will be good also with client side (front) and server side (back) communication ?
and how we make it ?

[gilpel]

Amazing content as usual Les, thank you.
I am wondering for which particular use you would go for gRPC communication rather than REST.
In my case, i have a bunch of computational microservices that need to communicate frequently and intensively together (1k-1Mb) and other microservices, more high level, that do not generate such heavy traffic and which are the ones that really require a UI to interact with. Do you think it would be a good idea to go for gRPC for the intensive ones and REST for the UI orientes onea. Or just gRPC for everyone and the jsonTrancoding layer for the higher level servicesthat will need webapp client to be plugged in for user interaction?

[iJEca]

You are fantastic!!!! Thank you for your effort for us

[rufetaliyev]

Thanks for this video. Can you explain how to use kafka in microservice like a pro?

[shababarshad]

hi @jackson how we can set arguments in request which are class or custom objects kindly tell if there is any solution

[freelancerweb]

thank u so much Sir, I think your channel the best for learn
