Hi @Enrico Rossini ,
if the C# code is getting a big long and we want to use a code behind file, we can get it instantly using the new extract block with code behind factoring
As we all known, when we create a Razor component, the component's UI is defined using Razor syntax, which consists of Razor markup, C#, and HTML. like this screenshot:
Since the above component also contains both the Html and the C# code, if the C# code is too long, it is hard to review or manage, so in Visual Studio 2022, there has a new feature, it can extract the content of the
@code block to a code behind class file:
For example, in the above FirstComponent component, assume the C# code is too long, we can move the focus between the
code (or use the
. key), it will show the "Extract block to code behind" option, after selecting it, it will generate the FirstComponent.razor.cs class file which contains the content of the
@code block. Refer this screenshot:
