I remember 15 years ago WCF and SOAP was the next big thing and at some point around 2012 REST was considered "the way" to get around all the complexity (which in many ways it did) and now we are back to where we started with gRPC. This is nuts. Nice course though... I do learn a lot from your courses and appreciate the effort.

Well, REST is still a thing and gRPC won't replace it (I don't think) because of how simple it is. gRPC, though, will definitely be a major player for a while yet, since it is so fast and versatile. The biggest thing going for it, though, is the fact that it is an industry standard instead of a Microsoft-specific product.

thx Corey, you really helped us out a lot in getting to understand gRPC since for students it's not the most ez task to fullfill. Hope you stay as amazing as you are, Greetings Max

I made another Tutorial before (where I had to read off the website) and it was a whole lot more complicated. It didn't really start from scratch anyways and never said anything about rebuilding. Instead there was a .bat file you had to run, which didn't really do the job. Anyway I braced myself and looked for a video tutorial. That usualy does it better for me anyways. Thinking it's gonna be complicated, and the Tutorial will take 1h raw video material, I was pretty surprised when I had a "Hello Linkario" coming back at me after about 28 Minutes. Thanks a lot, great tutorial and very well explained

Nice intro! I was on the verge of trying to port our WCF comm at work to gRPC, but after seeing your vid. I think it won't be that easy as I thought. We are using bi-directional channels for notifications and also file streaming with continuation (when communication drops and whole call timeouts, it can continues with the next call where it left off).

Thanks Tim. As always it is clear and nice presentation. GRPC reminds me WCF somehow. I think it is nice for mircoservices architecture. Because the communication should be as fast as possible and probably closed for connections from outside of the solution. Another point is streaming. It reminds me a short time subscription. Let’s assume we have a client which should receive some messages from a server. So it should establish a connection to server 1st and then some notifications keep arriving till a client keeps connection open. I think it can be useful feature. Thanks again Tim.

Hi Tim; Thanks for this great course. I'd like to make a suggestion. You had made an offer to those who are Patreon (with >$10 Level) with the Tips & Tricks. The problem is that, the notion of Patreon has become overly used by so many developers and people that is hard to get involved with a Patreon with someone, just because you need a source code or a tip sheet and etc. Next thing you know, you're paying a bunch of money every month where you're not using anything. Because of this, I see less and less people get involved in Patreon unless, they're using the product on daily basis. My suggestion is create your tip sheet or source code or whatever you have and sell it in your store AS IS with one purchase, rather asking people to commit to monthly payment. Imagine you go buy a pair of shoes and store owner says, you have to pay $10 per month for one year. To consumer if feels they're getting locked down. But if he says, it's price is $120, it's much easier for that consumer to pay $120 and walk out being free. Give us a price for the Sheet/Tip sheet. If it sounds fair, we'll buy it. Hope this helps!

Hi Tim, I really like your channel. Although I am watching this video for the. first time, it seems that gRPC is going to be used to replace WCF at some point in .Net Core. It is much like WCF with capabilities beyond what WCF can do. I agree that it should be used only when needed just as WCF. You still have services and contracts like WCF has but in an industry standard across all platforms and languages as you stated. As you said, web apps would be a much better solution.

Hi Tim, as usual great stuff. Just one question: I need to build a system where there are one or more servers which are connected to hardware devices which stream bytes to the server/s and that stream of bytes needs to be sent to the client to do some processing with the data. So, is gRPC a good choice for such a scenario? The data is sent in packets of 1KBytes at most to the server.

Probably. The client will need to implement the gRPC contract, but gRPC is designed to do streaming in two directions (if needed).

I found a strange bug in VS2019 with the .proto Build Action. When you make changes to an existing proto file (or copy it over from the server to the client), VS may leave a bunch of red squiggly lines from the "using GrpcServer" and elsewhere in your client program.cs file. The solution was to change the Build Action from Protobuf to None, then save, then change None back to Protobuf again (go figure). I'm using DotNet5 to follow this tutorial (great tutorial, by the way. Thanks!) and it's pretty much working correctly - same with the "Client only" part - they fixed that bug.

I have Published and deploy on my local Win10PC which all works and then configured as Windows service which Services appears that it start the application as well. However the problem I am experiencing, as a new developer in gRPC is this: If I run the 'exe' manually, and I run the gRPC client on the same machine as localhost everything works fine just like your video. However, if I run the client from a remote PC on a local network (all firewalls disabled just to be sure) the gRPC server doesn't seem to respond, in fact the gRPC server has trouble responding when running from the service when I run the client in local host. We are writing in the current .Net Core 3.1, to take advantage of improvements. I am hopeful that you, or one of your loyal watchers, may have some insight as to what I could be missing. Any help is appreciated.
