The answer, in case the question does not get enough reopen votes, is that you need to invoke the dll using `dotnet <dllname>`. 
The easiest way to make sure that this works is to publish the app from Visual studio **Build > Publish To Folder...** and add 
a script like the following in the produced folder.
```bash
#!/bin/bash
APP_NAME="HelloWorld" # Replace this with your app name
DIR="$(dirname ${BASH_SOURCE[0]})"
dotnet "$DIR"/"$APP_NAME".dll
```

 * Calculates an array of line end "positions" for a given string.

 * In this context a "position" is the zero-based index of a newline
