How to know Class ? Is there a way for Intellisense to autocomplete ?

Question

I have been using a 2d engine called NEZ. They use a List of class objects called "components" that are attached to an entity. Component is a public class that can be inherited.

Like let's say:

public class Ninja : Component

This is the Code:

/// <summary>
/// Adds a Component to the components list. Returns the Component.
/// </summary>
/// <returns>Scene.</returns>
/// <param name="component">Component.</param>
/// <typeparam name="T">The 1st type parameter.</typeparam>
public T AddComponent<T>(T component) where T : Component
{
    component.Entity = this;
    Components.Add(component);
    component.Initialize();
    return component;
}

/// <summary>
/// Adds a Component to the components list. Returns the Component.
/// </summary>
/// <returns>Scene.</returns>
/// <typeparam name="T">The 1st type parameter.</typeparam>
public T AddComponent<T>() where T : Component, new()
{
    var component = new T();
    component.Entity = this;
    Components.Add(component);
    component.Initialize();
    return component;
}

So the thing that is annoying is that Visual Studio doesn't give me a list of class objects that have the Component in them.

So, how would I know that _animator = Entity.AddComponent<SpriteAnimator>(); is a Component?

Besides that obvious answer that I would have to look at each .CS file and see if they inherit the Component class.

The question is: The object in <T> doesn't auto complete or doesn't even give me a possible items to fill the blank.

Is there a way for IntelliSense to search for each object that inherits the class Component?

If not, do you know if other IDE or intelli-tool (like Resharper) does the job?

I'm using Visual Studio 2019 with Roslynator Refactorings addon and also using Visual Assistance from Tomatoes Software.

Object Browser and look for descendants of Component? Also, https://stackoverflow.com/questions/282377/visual-studio-how-do-i-show-all-classes-inherited-from-a-base-class has some useful stuff — Caius Jard, Jun 19 '21 at 05:22

I figure you'll only do it once/put the output in a text file.. — Caius Jard, Jun 19 '21 at 05:30
No, there is no possibility to restrict intellisense to types allowed for a generic type parameter. The entry will scroll down a list of all types. You can send a [feature suggestion](https://learn.microsoft.com/visualstudio/ide/suggest-a-feature) to the .NET development team to *be able to filter on where clauses*. It's a good, intuitive and logic idea. Otherwise, indeed, you can take a llok on ReSharper or [TypeHierarchyViewer](https://marketplace.visualstudio.com/items?itemName=munyabe.TypeHierarchyViewer). — , Jun 19 '21 at 05:40
that would be a nice improvement. Also like just searching for a class implementing an interface that would be great, like `IPoint a = new ` and then there is a proposal of differen IPoint implementations — user287107, Jun 19 '21 at 11:25
