SetupIOCInternal generated contents are empty?

[Shane-KBT]

Prerequisites

• I have searched this repository's open and closed issues for duplicates.
• I am using the latest stable release.

What happens

Okay, so if I make a new console project and copy/paste the "Complete Example" code over Program.cs, the last line to GetService() returns null.

What you expected instead

Clearly it should have returned an instance of UserService.

Minimal reproduction

Copy/paste the "Complete Example" from the top level README.md into a fresh C# Console project.

Steps to reproduce

1. create new console project
2. add Splat and this nuget package
3. Copy/paste example
4. Set breakpoint on last line
5. Run/Debug
6. Step over last line and see that userService is null

You can also inspect the Splat.DI.Reg.g.cs file and see that SetupIOCInternal() is empty..

Workaround

I've found that if I use using DI = Splat.SplatRegistrations; instead of using static Splat.SplatRegistrations;' and prefix all the RegisterXxx() calls with DI.` that things work. So I'm guessing this issue relates to the code generator not noticing the calls to the SplatRegistrations methods.

Additional information

I've also just tried via CLI on a Linux box--same result. This seems so fundamental that I must be doing something wrong, but I can't see what! TIA for any help (I can workaround for now) and my apologies if this is just a simple thing I've missed...
