- Assemblies cannot depend on the layer above it
- Assemblies below the Visual Studio layer cannot depend on the Visual Studio SDK (no dependency on IVsXXX) nor any CPS-VS assembly. This layer and below should be hostable and usable outside of Visual Studio.
- C# assemblies cannot depend on any VB assemblies and vice versa.
| Assembly | Description |
|---|---|
| Visual Studio Layer | |
| Microsoft.VisualStudio.ProjectSystem.CSharp.VS | Contains components to enable the opening and editing of C# projects within Visual Studio. |
| Microsoft.VisualStudio.ProjectSystem.VisualBasic.VS | Contains components to enable the opening and editing of VB projects within Visual Studio. |
| Microsoft.VisualStudio.ProjectSystem.Managed.VS | Contains components that are shared between C# and VB projects. Make note that eventually the expectation is that F# if it moves to CPS will eventually share much of its code with C#/VB. |
| Microsoft.VisualStudio.AppDesigner | Contains the "Application Designer", which hosts property pages in a document window. |
| Microsoft.VisualStudio.Editors | Contains resources and settings editors, and C#/VB property pages. |
| Host-Agnostic Layer | |
| Microsoft.VisualStudio.ProjectSystem.CSharp | Contains components to enable the opening and editing of C# projects agnostic of host. |
| Microsoft.VisualStudio.ProjectSystem.VisualBasic | Contains components to enable the opening and editing of VB projects agnostic of host. |
| Microsoft.VisualStudio.ProjectSystem.Managed | Contains components that are shared between C# and VB projects agnostic of host. |
Long term we expect more assemblies as we pivot and componentize based on:
AppModels
- WinForms
- WPF
- Web
- CoreCLR
