Extension Doesn't seem to be working in Godot 3.2.3RC4

**OS/device including version:**
Windows 10

**Issue description:**
1. Installed Godot CSharp extension
2. Create new project in Godot 3.2.3 RC4
3. Add a Node into the Scene
4. Attach new C# script.
5. Visual Studio opens

Expected:
Expected to see `Play In Editor`, `Launch`, or `Attach`

Actual:
Only see the Project name and it will not launch instead throwing an error of `A project with an Output Type of Class Library cannot be started directly`

**Screenshots of issue:**

**NOTES**
This worked just fine when using RC3. My guess is that when RC4 upgraded to the csproj sdk format, it broke compatibility.
