Problems with Mudblazor? "Found markup with unexpected name 'StandaloneCodeEditor'
Hey there,
I haven't been working with Blazor for that long. I currently use MudBlazor and am trying to integrate BlazorMonaco.
If I test the following code:
<StandaloneCodeEditor Id="my-editor-instance-id" />
The following error message appears:
Found markup element with unexpected name 'StandaloneCodeEditor'. If this is intended to be a component, add a @using directive for its namespace.
I followed the guide. My _Layout.cshtml currently looks like this:
@using Microsoft.AspNetCore.Components.Web
@namespace NetLock_Web_Console.Pages
@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<base href="~/" />
<link href="https://fonts.googleapis.com/css?family=Roboto:300,400,500,700&display=swap" rel="stylesheet" />
<link href="_content/MudBlazor/MudBlazor.min.css" rel="stylesheet" />
<component type="typeof(HeadOutlet)" render-mode="Server" />
</head>
<body>
@RenderBody()
<div id="blazor-error-ui">
<environment include="Staging,Production">

</environment>
<environment include="Development">

</environment>

My Imports like this:
@using System.Net.Http
@using Microsoft.AspNetCore.Authorization
@using Microsoft.AspNetCore.Components.Authorization
@using Microsoft.AspNetCore.Components.Forms
@using Microsoft.AspNetCore.Components.Routing
@using Microsoft.AspNetCore.Components.Web
@using Microsoft.AspNetCore.Components.Web.Virtualization
@using Microsoft.JSInterop
@using MudBlazor
@using NetLock_Web_Console
@using NetLock_Web_Console.Shared
@using Blazored.LocalStorage
@using BlazorMonaco
@using BlazorMonaco.Editor
@using BlazorMonaco.Languages
Is there possibly a problem with MudBlazor used in combination, or am I missing something simple? Help is really appreciated.
I have tested MudBlazor (6.16.0) together with BlazorMonaco (3.2.0) and it works:
A specific *.blazor file:
<MudTabPanel Text="..." Icon="...">
<StandaloneCodeEditor ConstructionOptions="@this..." OnDidChangeModelContent="@this..." />
</MudTabPanel>
Imports:
@using System.Net.Http
@using System.Net.Http.Json
@using Microsoft.AspNetCore.Components.Forms
@using Microsoft.AspNetCore.Components.Routing
@using Microsoft.AspNetCore.Components.Web
@using static Microsoft.AspNetCore.Components.Web.RenderMode
@using Microsoft.AspNetCore.Components.Web.Virtualization
@using Microsoft.JSInterop
@using MudBlazor
@using BlazorMonaco
@using BlazorMonaco.Editor
@using BlazorMonaco.Languages
App.razor (I use the latest template of .NET 8):
<!DOCTYPE html>

@SommerEngineering Thank you for your contribution. That's strange. I was using an older template & just updated MudBlazor. I double checked and it still doesn't work. I will look into it further when the time is right. Thank you!
