Estuve observando este código aleatorio en GitHub:
https://github.com/HearthSim/HDT-Voice/blob/master/HDT-Voice/HDTPlugin/Github.vb y a raíz de eso se me ocurrió la idea de implementar un sistema reutilizable y sofisticado (o al menos yo creo que lo es) para obtener las releases de GitHub, con lo que poder determinar si existe una nueva release y por ende nuestro programa debe actualizarse...
Para comenzar la implementación de dicho sistema declaré las siguientes clases:
GitHubRelease,
GitHubAsset y
GitHubAuthor las cuales servirán para representar información de una release, un asset y un author/uploader. Y por último declaré una clase con nombre
GitHubUtil en donde declaré varias funciones sincrónicas y asincrónicas para implementar las siguientes funcionalidades: obtener todas las releases de un repositorio, obtener la última release, obtener una release con versión específica, y comprobar si existe una versión más reciente (para actualizar nuestro programa).
Estoy seguro que les servirá para sus aplicaciones de código abierto y le podrán sacar varias utilidades con diferentes fines que se ajusten a sus necesidades...
Aquí lo tienen todo:
