Plantillas con .net y C# Estoy aprendiendo a utilizar el framework .Net utilizando C# mientras desarrollo una mini aplicación.
La cosa es la siguiente, quiero saber cómo se hace una "plantilla" en .Net. Cuando digo "plantilla" me refiero a una ventana con un formato estándar que pueda utilizar en varias ventanas de la aplicación.
Buscando en Google encontré este tutorial, bastante bueno y explicativo, el problema es que dicen como hacer la plantilla, pero nunca dicen como invocarla.
Otra duda que tengo sobre lo mismo es la siguiente: si yo no quisiera una plantilla para una ventana completa, sino más bien para un pequeño formulario que debe aparecer en varias ventanas ¿cuál sería el procedimiento?
Espero que alguien pueda ayudarme. Agrego que aún no estoy completamente familiarizado con .Net y su librería de clases, así que hagan sus explicaciones de forma tal que yo pueda entenderlas.
Muchísimas gracias.
