ASP.NET Core gRPC for WCF Developers

What do you think could be improved in this book?

I'll provide quotes from the book and my for each of them.

Quote from the book:
https://docs.microsoft.com/en-us/dotnet/architecture/grpc-for-wcf-developers/grpc-overview
...general purpose RPC infrastructure. Stubby, renamed gRPC, now could take advantage of standardization and would extend its...

Accuracy: technically stubby hasn't been renamed to gRPC. gRPC is a completely different code base rewritten from scratch, learning from long history of stubby at google and heavily inspired by many of its feature (and also avoiding some of its problems)

Quote from the book:
https://docs.microsoft.com/en-us/dotnet/architecture/grpc-for-wcf-developers/why-grpc
As already discussed, using HTTP/2 rather than HTTP/1.1 removes the requirement for human-readable messages and instead uses the smaller faster binary protocol. ...

Accuracy:
I think the overall message is ok, but it's mixing up two concepts: 1. HTTP/2 binary framing which makes http itself more efficient and easier to parse vs HTTP1.1 being a text based protocol 2. whether the actual payloads/messages are binary or not (you can have a binary protobuf payload with HTTP1.1, but you won't have other advantages of HTTP2)

Quote from the book:
https://docs.microsoft.com/en-us/dotnet/architecture/grpc-for-wcf-developers/why-grpc
...gRPC allows clients to specify a maximum time for an RPC to complete. If the specified deadline is exceeded the server can cancel the operation independently of the client...

Fine to leave as is, but technically speaking when the deadline is exceeded, both server and client will cancel and be notified of it (due to clock differences one partly can cancel slightly sooner than the other one and grpc internal logic needs to handle that correctly).

The section "how protobuf works" here https://docs.microsoft.com/en-us/dotnet/architecture/grpc-for-wcf-developers/protocol-buffers feels like it focuses too much on serialization speed and efficiency, but doesn't really mention one of the protobuf's biggest features: the extensibility. Protobuf gives people the ability do develop evolving APIs while maintaining 100% backward compatibility of their services (which in some respect is more important than pure speed, big portion of userbase cares about usability not speed).

Quote from the book:
https://docs.microsoft.com/en-us/dotnet/architecture/grpc-for-wcf-developers/protobuf-messages
...Note that the Protobuf compiler applied PascalCase to the property names although they were camelCase in the .proto file. It's best to use camelCase in the message definition so that the code generation for other platforms produces the expected case for their conventions...

Accuracy: Actually, according to the protobuf code style, the field names should be lower_case_with_underscore, not camelCase. See e.g. .proto definitions for official google APIs in this repository: https://github.com/googleapis/googleapis/blob/master/google/cloud/vision/v1p2beta1/web_detection.proto

Protobuf reserved fields
https://docs.microsoft.com/en-us/dotnet/architecture/grpc-for-wcf-developers/protobuf-reserved

My hunch is that the "reserved" keyword is not really used much in practice, it might be
useful to do a bit of research on how people actually handle this. My understanding is that the most common situation would be that one party has a newer .proto file with a new field and the other party has and older version of the same proto (where the field is missing). The "reserved" scenarios are not that common IMHO. I can find out more information on this if needed.

Quote from the book:
...Metadata is handled using the Metadata class from the Grpc.Core NuGet package. This class can be used with collection initializer syntax....
https://docs.microsoft.com/en-us/dotnet/architecture/grpc-for-wcf-developers/metadata

The metadata class is actually in Grpc.Core.Api nuget. (Background: it used to be in Grpc.Core package, but then it was refactored out to a separate package with shared gRPC API. It had to stay under the same namespace Grpc.Core though for backwards compatibility reasons)

What do you like about this book?

Overall I got a good impression about both accuracy and usefulness of the book. Thanks for writing this!

Additional context

I'm one of the maintainers of the gRPC project and after reading through the book, I had some (mostly minor) comments, as summarized above.

Hello

Maybe, this part can be improve a little bit . For me, it confunse me little bit. In page 277 there is :
"A command handler receives a command and obtains a result from the aggregate that is used. The
result should be either successful execution of the command, or an exception."
But later when talking about MediaR :
"Here the behavior is raising an exception if validation fails, but you could also return a result object,
containing the command result if it succeeded or the validation messages in case it didn’t. This would
probably make it easier to display validation results to the user"
After re-reading I understood, that this is for the validation of the command, and the Handle of the command was not call at this point. Is still being validated. But in my opinion it would be better to refer that. That we are in the validation phase. That's
return object is not wrong.

Hi 👋

I was going through the documentation and I found a link that doesn't seem to be working.

Title: NET-Microservices-Architecture-for-Containerized-NET-Applications.pdf

The following sentence on p. 20 needs re-wording:
So, when you “look” at the filesystem after the layer has been copied, you see all the files, included the layer when the program was installed.

Perhaps they meant "... included in the layer..." ?

Hi there,

thanks for your great ebooks on Microsoft technologies.

I am very fond of reading the microservices ebook and I recently found out that there is an updated version of it available for MS .NET Core 3.1:
https://github.com/dotnet-architecture/eBooks/blob/master/current/microservices/NET-Microservices-Architecture-for-Containerized-NET-Applications.pdf

So far, there have been the following formats for the book:

• EPUB
• MOBI
• AZW3
• PDF

However, the current version for MS .NET Core 3.1 is available as PDF only. So, could you also provide the ebook in the other formats mentioned above? It is way more convenient to read MOBI or EPUB on an ebook reader instead of a PDF file.

Thanks again.

Chapter 7 makes a clear assumption that there is a backing SQL store. This is not always the case, and especially true in "cloud-native" apps where content is retrieved from APIs which are not always controlled by the application owner. Chapter 10 has a faint reference to microservices and n-tier architecture which dominate modern app development. I'm not sure why MS publications are so focused on EF data access and leave the broader cross-cutting concerns of API development out of scope.

Chapter 8 is well laid out, but does not provide guidance for implementation of functional tests. This is critical in CD environments, and there is very little guidance available.

What do you like about this book?
Overall well written and illustrated.

I went through the "Forms and Validation" example and it worked fine but it triggered the thought "the UI looks rubbish for the errors, looks a bit rubbish , basic" , so it would be good to have a section describing how you could make it look better / more modern UI like below

https://cvlrsnergpublic001.blob.core.windows.net/public/NiceUI.jpg

What do you like about this book?
As a Web Forms hack , ive found solutions in the book that I couldn't find in Google .. ie how to do Response.Redirect equivalent , so good stuff .

Additional context
It would be nice to have a cheat sheet , ie like the Response.Redirect example above . Top 20 or so thing u do in Web Forms , and the equivalent thing in Blazor

I come from a Backend, Infrastructure / DevOps background and Web Forms made it very easy for me to quickly produce functional web sites , linking to SQL etc with very little knowledge , understanding of ViewState, Html , CSS, javascript .

Seems to me with Blazor , you have to understand html , CSS and all this stuff. So anything to ease this transition would be good.

thanks again
Andy.
