API de NuGet en Visual Studio
Además de la interfaz de usuario y la consola del Administrador de paquetes en Visual Studio, NuGet también exporta algunos servicios útiles que otras extensiones pueden usar. Estas interfaces permiten que otros componentes de Visual Studio interactúen con NuGet, que se puede usar para instalar y desinstalar paquetes, y para obtener información sobre los paquetes instalados.
NuGet proporciona servicios mediante dos tecnologías diferentes, cada una con sus interfaces definidas en un paquete NuGet diferente. Los servicios más antiguos de NuGet están disponibles desde Managed Extensibility Framework (MEF), que están disponibles en el paquete NuGet.VisualStudio (vaya a los servicios MEF de NuGet). Hay API más recientes, diseñadas para poder usarse con código de async, disponibles en el paquete NuGet.VisualStudio.Contracts, mediante IServiceBroker de Visual Studio (vaya a Servicios de intermediación de NuGet).
Versiones del paquete
El producto de NuGet sigue la versión de Visual Studio, pero está detrás de las versiones 11.0. Por ejemplo, NuGet 6.0 se corresponde a Visual Studio 2022 17.0, NuGet 5.11 se corresponde a Visual Studio 2019 16.11, etc.
A partir de Visual Studio 17.1, los paquetes de API de extensibilidad de Visual Studio de NuGet coinciden con la versión de Visual Studio que tienen como destino las API. Por ejemplo, se debe usar la versión del paquete 17.1.0 de NuGet.VisualStudio y NuGet.VisualStudio.Contracts cuando la extensión tenga como destino Visual Studio 17.1 y versiones posteriores. En Visual Studio 17.0 y versiones anteriores, las versiones de paquetes NuGet son las mismas que la versión del producto de NuGet. Por ejemplo, si la extensión tiene como destino Visual Studio 2022 versión 17.0, debe usar la versión 6.0 de los paquetes de extensibilidad de Visual Studio de NuGet.
SDK cliente de NuGet en extensiones de Visual Studio
Solo las API en NuGet.VisualStudio y NuGet.VisualStudio.Contracts se admiten en extensiones de Visual Studio.
NuGet proporciona redirecciones de enlace para estos ensamblados, por lo que estos ensamblados no necesitan incluirse en la extensión.
No se admite el uso de paquetes del SDK cliente de NuGet, por ejemplo NuGet.Protocol, en extensiones de Visual Studio.
NuGet no proporciona redirecciones de enlace para estos ensamblados.
Para obtener más información, consulta la política de soporte técnico del SDK cliente de NuGet.

NuGet.SolutionRestoreManager
Estas interfaces están diseñadas para que los sistemas de proyectos interactúen con NuGet, lo que permite al sistema de proyecto notificar a NuGet los cambios en PackageReference y orquestar las actualizaciones por lotes. Es probable que las extensiones de Visual Studio que no sean sistemas de proyecto no se beneficien de estas API.

Uso de servicios de NuGet
Advertencia
No use ningún otro tipo aparte de las interfaces públicas en el código y no haga referencia a ningún otro ensamblado de NuGet, como NuGet.Protocol.dll, NuGet.Frameworks.dll, etc.
Para maximizar las promesas de compatibilidad con versiones anteriores que realizamos, pero también proporcionar la flexibilidad de implementar nuevas características, mejoras de rendimiento y correcciones de errores en Visual Studio, no se admite el SDK de cliente de NuGet que se usa en Visual Studio y no proporcionamos redirecciones de enlace en devenv.exe.config a ensamblados distintos de nuestros contratos de extensibilidad de VS.
Si quiere una nueva API relacionada con NuGet en Visual Studio, busque el repositorio principal de NuGet y vote a favor cualquier problema existente si encuentra uno similar. Si no encuentra una solicitud de característica existente que votar a favor, cree una.
Servicios de intermediación
Instale el paquete
NuGet.VisualStudio.Contractsen el proyecto, además deMicrosoft.VisualStudio.SDK.Use
IAsyncServiceProviderpara obtener el agente de servicios de Visual Studio y úselo para obtener el servicio de NuGet. Tenga en cuenta queAsyncPackageextiendeIVsAsyncServiceProvider2, por lo que la clase que implementaAsyncPackagese puede usar comoIAsyncServiceProvider. Vea también la documentación enIBrokeredServiceContaineryIServiceBroker// Your AsyncPackage implements IAsyncServiceProvider IAsyncServiceProvider asyncServiceProvider = this; var brokeredServiceContainer = await asyncServiceProvider.GetServiceAsync<SVsBrokeredServiceContainer, IBrokeredServiceContainer>(); var serviceBroker = brokeredServiceContainer.GetFullAccessServiceBroker(); var nugetProjectService = await serviceBroker.GetProxyAsync<INuGetProjectService>(NuGetServices.NuGetProjectServiceV1);Cuando el código ya no necesite el servicio de intermediación de NuGet, elimínelo. Por ejemplo, si solo necesita el servicio de intermediación de NuGet durante una llamada de método, puede encapsularlo en una instrucción
usingde C#:InstalledPackagesResult installedPackagesResult; using (nugetProjectService as IDisposable) { installedPackagesResult = await nugetProjectService.GetInstalledPackages(projectGuid, cancellationToken); }
Servicios MEF
Instale el paquete
NuGet.VisualStudioen el proyecto, que contiene el ensambladoNuGet.VisualStudio.dll.En NuGet 5.11 y versiones anteriores, el paquete establece automáticamente la propiedad Insertar tipos de interoperabilidad de la referencia de ensamblado en True. Se ha cambiado la directiva de Visual Studio 2022 con respecto a los tipos de interoperabilidad de inserción, por lo que en el paquete NuGet.VisualStudio versión 6.0.0 y posteriores ya no se usa.
Para usar un servicio, impórtelo a través del atributo Import de MEF o del servicio IComponentModel.
//Using the Import attribute [Import(typeof(IVsPackageInstaller2))] public IVsPackageInstaller2 packageInstaller; packageInstaller.InstallLatestPackage(null, currentProject, "Newtonsoft.Json", false, false); //Using the IComponentModel service var componentModel = (IComponentModel)GetService(typeof(SComponentModel)); IVsPackageInstallerServices installerServices = componentModel.GetService<IVsPackageInstallerServices>(); var installedPackages = installerServices.GetInstalledPackages();
Como referencia, el código fuente para NuGet.VisualStudio se encuentra dentro del repositorio NuGet.Clients.
Descripción de los sistemas de proyectos de .NET
Cuando se agregaron proyectos de estilo SDK para .NET Core 1.0, se diseñó para ser más asincrónico que los sistemas de proyectos anteriores de Visual Studio. Esto afecta al modo en que todos los demás componentes de Visual Studio interactúan directamente con él, o bien por medio de otros componentes, como NuGet. Esto es más notable en la carga de soluciones y de proyectos, donde los proyectos no están totalmente disponibles algún tiempo después de que las notificaciones de API sincrónicas más antiguas de Visual Studio ya se hayan desencadenado.
Durante la carga de la solución, NuGet omite IVsSolutionEvents.OnAfterProjectLoad, para evitar retrasar la parte sincrónica de la carga de la solución. NuGet sincronizará sus estructuras de datos internas una vez que se complete la parte sincrónica de la carga de la solución. Esto también es cierto para proyectos de estilo que no son SDK.
Incluso después de que finalicen todos los controladores de eventos IVsSolutionEvents.OnAfterSolutionLoad, esto solo indica el final de la parte sincrónica de la carga de la solución. La parte asincrónica de la carga de la solución todavía está en curso. Por tanto, si la extensión llama a API de NuGet como GetInstalledPackagesAsync o InstallPackage poco después de la carga del proyecto o la solución, NuGet podría iniciar una excepción InvalidOperationException con un mensaje similar a "No se pudo cargar la operación como detalles del proyecto {nombre del proyecto}".
Cuando una solución contiene al menos un proyecto de estilo SDK, NuGet realizará automáticamente una restauración después de la carga de la solución y no debe llamar a ninguna API de Nuget hasta que se complete. Puede usar IVsNuGetProjectUpdateEvents para obtener una notificación cuando se restaure la solución o cuando se restaure un proyecto específico. Si una solución no contiene ningún proyecto de estilo de SDK, la restauración no se programará automáticamente y es posible que no se produzca hasta que se programe una compilación.
Para determinar si un proyecto usa el flujo asincrónico de NuGet (proyecto de estilo SDK), use PackageUtilities.IsCapabilityMatch con la expresión CPS + PackageReference.
