VS Code refuses to debug my godot C# project. I get this fun message:

'E:\Godot\Projects\defendtheboard\DefendTheBoard.csproj' does not support debugging. No launchable target found.

I have copied and tried like 6 different launch.json and task.json setups and I still get the same message. This seems like something that should require no configuration and should just work automatically. I have the following extensions for VS Code:

.NET Install Tool C# C# Dev Kit C# Tools for Godot Godot .NET Tools Godot Docs for C# Intellicode for C# Dev Mono Debug

I have not programmed in a long time and I would be happy to admit that I did something foolish. Please help me identify my own failures.

Ok here is the .csproj, missing the exe line as pointed out:

<Project Sdk="Godot.NET.Sdk/4.4.0">
  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <EnableDynamicLoading>true</EnableDynamicLoading>
  </PropertyGroup>
</Project>

here is the .sln:

A quick glance and file search did not reveal anything named "Directory..."
