Escribir código para diferentes tipos de elementos de trabajo usando el modelo de objetos de cliente para Team Foundation
Cuando se escribe código para diversos proyectos de equipo, puede realizar la misma función en diferentes tipos de elementos de trabajo que respondan a propósitos similares. Estos tipos pueden ser distintos porque proceden de las plantillas de procesos, o un equipo podría haber personalizadolas para un proyecto de equipo concreto. Por ejemplo, puede realizar la misma función en los requisitos y artículos de usuario, que deben representar qué clientes necesitan y valoran. En lugar de escribir código independiente para cada tipo de elemento de trabajo, puede generalizar el código para trabajar para ambos. Además, un equipo puede haber personalizado la definición del elemento de trabajo para los casos de usuario para que los miembros del equipo puedan calcular el trabajo en horas en lugar de en los puntos de caso. Puede evitar duplicar su propio esfuerzo ajustando el código para controlar el valor predeterminado y estrategias personalizadas.
En este tema, encontrará un ejemplo de código que realiza una tarea en un tipo específico de elemento de trabajo que no se ha personalizado, y podrá saber cómo refactorizar de codificación para admitir algunas clases de personalizaciones. Para obtener más información sobre cómo personalizar los tipos de elementos de trabajo, vea Visión de un extremo a otro sobre lo que se puede configurar y personalizar en Visual Studio TFS.

Imprimir los árboles de los casos de usuario con estimaciones en puntos de caso
Imprimir los árboles de los casos de usuario con estimaciones en puntos o trabajo previsto de caso Either
Imprimir los árboles de elementos de trabajo que se usaron como requisitos con estimaciones
Imprimir los árboles de los casos de usuario con estimaciones en puntos de caso
Este ejemplo de código imprime los árboles de todos los casos de usuario en cada proyecto de equipo en un servidor e incluye las estimaciones para cada artículo que no tiene ningún elemento secundario. Para usar este ejemplo, se crea una aplicación de consola, agregue referencias a los ensamblados siguientes y, a continuación reemplaza el contenido Program.cs (o Module1.vb) con el código siguiente.

Imprimir los árboles de los casos de usuario con estimaciones en puntos o trabajo previsto de caso Either
Este ejemplo modifica el método de PrintTrees para determinar si cada elemento de trabajo utiliza puntos de caso coloca o el trabajo previsto e imprimir la estimación de ese campo. Para usar este ejemplo, se reemplaza la línea Console.WriteLine(target.Fields["Story Points"].Value); en el método de PrintTrees con el código siguiente.
// Determine which estimation field is present
string fieldName = "Story Points";

Puede agrupar en categorías diferentes tipos de elementos de trabajo que respondan a mismo o para los propósitos similares en diferentes proyectos de equipo.
