INTRODUCCION

La gama de productos de Visual Studio comparte un único entorno de desarrollo

integrado (IDE) que se compone de varios elementos: la barra de menús, la barra de

herramientas Estándar, varias ventanas de herramientas que se acoplan u ocultan

automáticamente a la izquierda, en la parte inferior y a la derecha, así como en el espacio

del editor. Las ventanas de herramientas, menús y barras de herramientas disponibles

dependen del tipo de proyecto o archivo en el que esté trabajando.

La gran mayoría de programadores de VB.NET utilizan el entorno de desarrollo integrado

Microsoft Visual Studio en alguna de sus versiones (desde el primer Visual Studio .NET

hasta Visual Studio .NET 2012, que es la última versión de Visual Studio para la plataforma

.NET), aunque existen otras alternativas, como SharpDevelop (que además es libre).

Al igual que con todos los lenguajes de programación basados en .NET, los programas

escritos en VB .NET requieren el Framework .NET o Mono para ejecutarse.



INSTALACION DE VISUAL BASIC 2010

Instalar mediante los discos de instalación

Para instalar Visual Studio, ejecute primer Setup.exe, que se encuentra en el directorio

raíz de los discos de instalación de Visual Studio.

Se iniciará el asistente para la instalación d Microsoft Visual Studio 2010 (versión de evaluación). Pulsaremos en "Instalar Microsoft Visual Studio 2010":

Seguir los pasos indicados en la instalación.

Tras el proceso de instalación puede que pida reiniciar el equipo:



Una vez instalado el programa ya se puede seguir utilizando este:
