Thanks for the book! I really like your style and I think this is another great resource I'll get a lot out of. One of my concerns about .NET core is it seems that there are a handful of ways to do things compared to Java. But I'm starting to like the fact that there are fewer options that work really well. Plus there are things like LINQ that I haven't seen used much elsewhere that blow my mind.

LINQ and the async/await pattern are my two all-time favorite things about C#.

Isn't LINQ quite slow?

I would like to see a version for REST and SPAs as well

Agreed! It's great that the book is published under an open license - my first thought was that it'd be fun to port this to f# - and my second thought was to restructure it a bit, focusing on REST/SPA.

Having read through it, it is indeed nice and concise - but I'm of two minds of the content - is it really good to introduce server side rendering with jquery and ajax - today?

I think, that showing server side rendering is good, for a beginner (how do I go from a form, to db, and back to a simple html table?) - but I'm not sure how useful the "half-way to smart client"-approach of jquery is. I'm almost convinced throwing out most of the server side rendering in favour of returning json and rendering everything client side would be better, than the "in between" approach.

Now you have rendering and interaction spread over server side views and client side javascript - and I'm not sure I like the path it sets up for new developers.

But for someone that "grew up" with the html to html+ajax it made the book very accessible, and manages to show off a remarkably broad and (apparently) useful section of asp.net core to someone not well versed in asp.net core.

Enjoying the book, I'm new to to asp and razor although I have done a little .net wep api before. I have an issue with the first view, when running I get the error below on all references in the cshtml. I'm using a stock install of VS 2017. Any ideas? /Views/Todo/Index.cshtml(4,5): error CS0103: The name 'ViewData' does not exist in the current context /Views/Todo/Index.cshtml(8,33): error CS0103: The name 'ViewData'…

Did you also install the .Net Core 2.0 SDK?

Not yet, and I was thinking that this might be the issue - would you expect this to be required?

dotnet --version shows 1.1.0, I think I assumed that the latest VS2017 would have the latest dotnet core but this doesn't seem to be the case.

This is a common misconception, VS2017 doesn't ship with the .Net Core SDK, you need to manually install it seperatly. This is also described in the Book: https://nbarbettini.gitbooks.io/little-asp-net-core-book/con...

Thanks for pointing this out, this did indeed fix the problem. Somewhere in the installation I had ended up with 1.1 but it works fine now.

Very good points, thanks. I struggled with this myself as I was trying to plan out the structure of the book. I ultimately went with the "path of least resistance" (ASP.NET Core MVC ships with Bootstrap, jQuery, etc) but I agree that it could be better in future versions. :)

The "little" part is appreciated, as I recall all too vividly learning ASP.NET by slogging through "Beginning ASP.NET" by Imar Spaanjaars. It's a good book, don't get me wrong, but its two biggest strengths (thoroughness and being good for beginners) result in its being 800 pages long!

I have fond memories of learning VB3 from Teach Yourself Visual Basic in 21 Days, which had to be 500+ pages. It turns out it's tough to have a good introduction to a topic without going really long.

great starter book! Any plans of expanding it to a more advanced level? I would like to see elaboration on the async/await patterns and more on http verb support techniques and routing. I like your holistic but bare bones approach and I would pay for an advanced version of this book, especially if it included short exercises with answers after each chapter.

Thanks for the feedback! I don't have anything in the works right now, but will definitely consider it.
