dotnet new gitignore

Cuando creo un nuevo proyecto en GitHub, lo primero que agrego en el repositorio inicial es el archivo .gitignore porque no quiero tener basura en mi repo. 

No mucha gente sabe que dotnet cli proporciona un comando para crear un archivo .gitignore, prácticamente perfecto.

En la carpeta raíz del proyecto, ejecutamos el siguiente comando :

dotnet new gitignore

Y listo! Se genera un archivo .gitignore con el siguiente contenido : 

## Ignore Visual Studio temporary files, build results, and

## files generated by popular Visual Studio add-ons.
