[SUGGESTION] Class View

Describe the feature you'd like

Around two years ago, I had requested a Class View / Object Browser or a similar kind of namespace based code navigation tool in the vscode-csharp project: https://github.com/dotnet/vscode-csharp/issues/4759.

Now that the C# development experience in VSCode is being revamped, can we please consider the above suggestion in the feature backlog? The rationale being, in C#, code structure does not map 1:1 onto the file structure, hence to understand code organization, it is necessary to see the actual projects > namespaces > classes > members hierarchy.

Other attributes of the class view:

1. View inherited members of a class
2. View inheritance hierarchy (base classes and implemented interfaces)

Link to the Visual Studio panel:

Key text:

Class View is shown as part of Solution Explorer and as a separate window. Class View displays the elements of an application. The upper pane displays namespaces, types, interfaces, enumerations, and classes, and the lower pane displays the members that belong to the type selected in the upper pane. By using this window, you can move to member definitions in the source code (or in the Object Browser if the element is defined outside your solution).

Alternatives considered

Solution Explorer

This presents a semi-structured, file-oriented view.

File Explorer

This presents the raw directory structure of the project.

Environment Information

• OS: Windows
• VSCode: 1.79.2, 695af097c7bd098fbf017ce3ac85e09bbc5dda06, x64
• Extension: v0.1.103, Preview

The issue does not name implementation files or tests. Start by reviewing the C# Dev Kit and related extension code-navigation areas, then compare the prior vscode-csharp issue and the linked Visual Studio Class View description. Done would require an agreed scope and a working namespace, type, member, and inheritance view.
