How to add a Partial Class to a component in Blazor in Visual Studio 2019?

Question

I'm not finding where should I click to create a partial class in visual studio 2019.

After I create a new "Razor Component" file, I can't add the partial class to it.

Where do I add it?

Answer 1

There are two ways to add code behind to Razor component:

1. Add Base class and in component add @inherits this class, how is described in this answer . In this case base class shouldn't be partial.

2. Since October 2019 we can use partial classes . You can just add class name with the same name, adding .cs extension, mark it as partial class:

And you don't need to use @inherits in this case.

See Partial class support doc.

Answer 2

Something like this? : - razor page with "code-behind" class
