Blazor: Inherited component with no content displays as empty

I saw many examples of inherited components. They all look like:

Base.razor:
@code{
    //some code here.
}

Inherited.razor:
@inherits Base
<div>
    //some content here
</div>

Now what I’m doing is just on the other side:

Base.razor:
<div>
    //some content here
</div>

Inherited.razor:
@inherits Base

@code{
    //some code here, initializing parameters, override some methods.
}

But if I use

<Inherited></Inherited>

to render it, it’s empty. What shall I do then? Any help will be appreciated.

More real code here:

Base(CrudIndex2.razor):

@typeparam TItem where TItem : class, LibInterfaceBase.IIdable, new()

@inject Microsoft.Extensions.Localization.IStringLocalizer<GlobalRes> GlobalLocalizer

@if (!Loaded)
{
    <MudProgressCircular Color="Color.Primary" Indeterminate="true"/>
}
else
{
    <MudTable>...</MudTable>
}

Inherited:

@page "/AdaPPM/MeasureItemDefinitions/Index"
@inherits CrudIndex2<LibAdaMetrics.DataRecords.MeasureItemDefinition>

@code
{
//    int CurrentUser = await _authenticationManager.CurrentUser();
    protected override async Task OnInitializedAsync()
    {
        base.InitBase(
            typeof(CreateOrEditMeasureItemDefinitionDialog),
            AdaHubMeasureItemDefinitions.Instance);

        CurrentUser = await _authenticationManager.CurrentUser();
        CanCreate = (await _authorizationService.AuthorizeAsync(CurrentUser, Permissions.MeasurementBaselines.Create)).Succeeded;
        CanEdit = (await _authorizationService.AuthorizeAsync(CurrentUser, Permissions.MeasurementBaselines.Edit)).Succeeded;
        CanDelete = (await _authorizationService.AuthorizeAsync(CurrentUser, Permissions.MeasurementBaselines.Delete)).Succeeded;

        await ResetAsync();
        Loaded = true;
    }

>Solution :

Your Inherited.razor provides no content, and the content of the base class will not be rendered.

This specific case can be fixed by putting your derived class in a plain cs file:

Inherited.cs

public class Inherited : CrudIndex2
{
  ...
}

But a more common pattern is to turn that around: Base.cs and Inherited.razor

It will work as long as only 1 class is from a .razor file.
