Steps To Reproduce

1. Open new instance of VS Code
2. Create any new project through command palette

Expected Behavior

For the time it takes for the command palette items to pop up and walk me through the getting started experience to be more responsive/quicker

Environment Information

• Windows 11
• VS Code: 1.83.1
• C# Dev Kit: v0.5.150
• C#: v2.5.30

Is there any update on this? This is still really slow on a new instance of VS Code

[smitpatel]

The time it takes to show the list of templates is going to be little slower on new instance of VS Code since invoking the command has to start the C# dev kit extension too (which is already done if you are working with an open solution). So that experience difference is going to remain since we cannot activate extension in advance. We are trying to minimize the time as much as it allows.

I believe after choosing location, experience is slower because opening the workspace in VS Code. We will investigate and try to improve it.

The time from clicking "Create .NET project" until the dropdown shows up can be quite long... I first thought the button was broken, it must have taken 20s for anything to happen.

Closing and reopening VSCode and trying again it's much faster, but it's still at least 3-4 seconds right after opening VSCode, which is plenty of time to think "is this thing even working?"

This is on macOS, on an M2 Pro Mac Mini (not a particularly slow machine).

@timheuer if you need videos on this I can provide the user studies that show this
