Puede usar InPlaceHostingManager para escribir programas que instalan ClickOnceClickOnce aplicaciones mediante programación.You can use InPlaceHostingManager to write programs that install ClickOnceClickOnce applications programmatically. Por ejemplo, puede usar esta clase en un entorno controlado del software de administración del sistema (SMS) o en situaciones en las que necesite una instalación compleja que realice una serie de operaciones previas o posteriores a la instalación en el equipo local.For example, you can use this class in a controlled system management software (SMS) environment or in situations where you need a complex installation that performs a number of pre-installation or post-installation operations on the local computer. Por lo general, querrá usar los miembros de esta clase en un orden específico:Generally, you will want to use the members of this class in a specific order:

  1. Cree una nueva instancia de InPlaceHostingManager.Create a new instance of InPlaceHostingManager.

  2. Descargue el manifiesto GetManifestAsyncde implementación mediante.Download the deployment manifest by using GetManifestAsync.

  3. Compruebe que la aplicación se puede ejecutar con los permisos adecuados mediante el AssertApplicationRequirementsuso de.Check that the application can be run with the appropriate permissions by using AssertApplicationRequirements.

  4. Descargue e instale la aplicación DownloadApplicationAsyncmediante.Download and install the application by using DownloadApplicationAsync.

  • Si se llama a cualquiera de estos parámetros fuera de orden, se producirá una excepción.If you call any of these parameters out of order, they will throw an exception.

InPlaceHostingManagerpuede instalar una ClickOnceClickOnce aplicación, pero no puede ejecutarla.InPlaceHostingManager can install a ClickOnceClickOnce application, but cannot execute it. Algunos métodos de esta clase, Executecomo, se reservan para su uso al descargar una aplicación basada en Windows Presentation Foundation que se ejecuta dentro de un explorador Web.Some methods in this class, such as Execute, are reserved for use when downloading a Windows Presentation Foundation-based application that runs inside a Web browser.

Para usar InPlaceHostingManager para descargar e instalar aplicaciones de, debe asegurarse de que el certificado para firmar las ClickOnceClickOnce aplicaciones que planea instalar ya está instalado en los equipos cliente como un editor de confianza.To use InPlaceHostingManager to download and install applications, you must make sure that the certificate for signing the ClickOnceClickOnce applications you plan to install is already installed on client computers as a trusted publisher. Para obtener más información sobre los editores de confianza, consulte información general sobre la implementación de aplicaciones de confianza.For more information on trusted publishers, see Trusted Application Deployment Overview.

Nota

Actualmente hay una limitación de producto que evita InPlaceHostingManager que funcione correctamente al depurar el código con Visual Studio.There is currently a product limitation that prevents InPlaceHostingManager from working correctly when you debug your code using Visual Studio. Si depura la aplicación en Visual Studio mediante la tecla F5, el ejemplo producirá excepciones misteriosas al llamar a DownloadApplicationAsync.If you debug your application in Visual Studio by using the F5 key, the sample will throw mysterious exceptions when you call DownloadApplicationAsync. Para depurar con Visual Studio, inicie la aplicación sin depurar y, a continuación, adjunte el depurador.To debug using Visual Studio, start the application without debugging, and then attach the debugger. Como alternativa, puede usar otro depurador, como WinDbg.Alternatively, you can use another debugger, such as WinDbg.
