The type or namespace name 'RenderModeServerAttribute' could not be found (are you missing a using directive or an assembly reference?)

Question

In .Net 8 preview version I was using below code in .razor file

@using Server.Models;
@page "/movies/signalr"
@attribute [RenderModeServer]
@inject HttpClient Http

This is with blazor signalR render mode.

But in the final release version of .Net 8, I am getting the below error for @attribute [RenderModeServer]

The type or namespace name 'RenderModeServerAttribute' could not be found (are you missing a using directive or an assembly reference?)

Below one works, so I am assuming, it got changed in final release

@attribute [StreamRendering(true)]

Hi @Developer,

In .NET 8, you need use @rendermode attribute.

Sets the render mode of a Razor component:

• InteractiveServer: Applies interactive server rendering using Blazor Server.
• InteractiveWebAssembly: Applies interactive WebAssembly rendering using Blazor WebAssembly.
• InteractiveAuto: Initially applies interactive WebAssembly rendering using Blazor Server, and then applies interactive WebAssembly rendering using WebAssembly on subsequent visits after the Blazor bundle is downloaded.

More details refer to: @rendermodel definition
