根据以下步骤创建一个demo 1: Create a component @typeparam T1 2: Consume the component <ThatComponent T1=SomeTypeInAnotherNamespace/> 3: Click the quick-actions bulb and select @using ThatOtherNamespace how to create a demo according <ThatComponent T1=SomeTypeInAnotherNamespace/>

Sure, I can help you create a demo based on the steps you provided. Here's what you can do:

1. First, create a new component in your project using following code:

@typeparam T1

>
    <p>This is a component that takes in a parameter of @typeof(T1). </p>
</div>

2. Next, consume the component by adding the following code to a Razor page or another component:

<ThatComponent T1=SomeTypeInAnotherNamespace/>

Replace `SomeTypeInAnotherNamespace` with the name of a type in another namespace that you want to use as the type parameter for the component.

3. Finally, to resolve any namespace issues, click the quick-actions bulb (the lightbulb icon) that appears in Visual Studio or Visual Studio Code when you hover over the `SomeTypeInAnotherNamespace` parameter. From the menu that appears, select `@using ThatOtherNamespace` to add a using statement for the namespace where the type is defined.

That's it! You should now have a working demo of a component that takes a type parameter from another namespace.
