Problems with Mudblazor? "Found markup with unexpected name 'StandaloneCodeEditor'

0x100001 commented 5 months ago

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">
            An error has occurred. This application may no longer respond until reloaded.
        </environment>
        <environment include="Development">
            An unhandled exception has occurred. See browser dev tools for details.
        </environment>
        <a href="" class="reload">Reload</a>
        <a class="dismiss">🗙</a>
    </div>
    <script src="_framework/blazor.server.js"></script>
    <script src="_content/MudBlazor/MudBlazor.min.js"></script>
    <script src="js/custom.js"></script>
    <script src="_content/BlazorMonaco/jsInterop.js"></script>
    <script src="_content/BlazorMonaco/lib/monaco-editor/min/vs/loader.js"></script>
    <script src="_content/BlazorMonaco/lib/monaco-editor/min/vs/editor/editor.main.js"></script>

</body>
</html>

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>
<html lang="en">

<head>
    <meta charset="utf-8"/>
    <meta name="viewport" content="width=device-width, initial-scale=1.0"/>
    <base href="/"/>
    <link rel="stylesheet" href="app.css"/>
    <link rel="icon" type="image/png" href="favicon.png"/>
    <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" />
    <HeadOutlet/>
</head>

<body>
    <Routes @rendermode="new InteractiveServerRenderMode(prerender: false)"/>
    <script src="_content/BlazorMonaco/jsInterop.js"></script>
    <script src="_content/BlazorMonaco/lib/monaco-editor/min/vs/loader.js"></script>
    <script src="_content/BlazorMonaco/lib/monaco-editor/min/vs/editor/editor.main.js"></script>
    <script src="_framework/blazor.web.js"></script>
    <script src="_content/MudBlazor/MudBlazor.min.js"></script>
    <script src="app.js"></script>
</body>

</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!
