Usage shows Project name instead of the tool name.

Example I have something as follows :
I have Bar.csproj as follows.
```
true
foo
```
The usage of the command is shown as follows when we type the command foo.
```
Usage:
Bar [options] [command]

Options:
--version Display version information
```

I Was expecting :

```
Usage:
foo [options] [command]

Options:
--version Display version information
```

Is this a bug or by design? If not please advise on how to package. Thank you.
