Usage of `dotnet tools` on assemblies with CommandLineParser results in unexpected output

I was trying to add **CommandLineParser** to a _asp.net core_ project of mine to conditionally apply seed and test data on runs.

If I run any sort of tool on the assembly I get output from the Parser.

F.e. `dotnet ef migrations list`

```
ERROR(S):
Option 'applicationName' is unknown.

-s, --seed Seed required data.

-t, --test Seed data for dev and testing purposes.

-a, --auth Seed auth data.

--help Display this help screen.

--version Display version information.
```

I'm assuming that the tools themselves are passing these options or something along the line. Everything seems to work properly, but is this something other people have dealt with in some way?
