FAQ

What's the difference between DotVVM and Razor Pages? They are using MVVM too.

Razor Pages also use MVVM approach, but all the experience is done on the server. If the user interacts with the page, the page data are sent to the server and a new HTML is returned.

DotVVM is using Knockout JS library to do the MVVM experience in the browser. Most of the user interactions can be handled without involving the server, and if DotVVM needs to call the server, it is using AJAX so the page doesn't reload.

Do I need to learn JavaScript to use DotVVM?

No. Knowing just HTML and C# is enough to use DotVVM. DotVVM will do all the JavaScript "magic" for you.

However, if you take the web development seriously, we think that you should learn JavaScript eventually. You'll be able to achive much more – from using third-party components to extending DotVVM with custom behaviors.

Is DotVVM free?

Yes! DotVVM is an open-source project developed under the Apache 2.0 License, and is supported by the .NET Foundation. There is also a free extension for Visual Studio.
