NuGet-API in Visual Studio
Zusätzlich zur Benutzeroberfläche des Paket-Managers und zur Paket-Manager-Konsole in Visual Studio exportiert NuGet auch einige nützliche Dienste, die andere Erweiterungen verwenden können. Diese Schnittstellen ermöglichen anderen Komponenten in Visual Studio die Interaktion mit NuGet, über die Pakete installiert und deinstalliert werden können und Informationen zu installierten Paketen abgerufen werden können.
NuGet stellt Dienste über zwei verschiedene Technologien bereit, von denen jede ihre Schnittstellen in einem anderen NuGet-Paket definiert hat. Die älteren Dienste von NuGet sind über das Managed Extensibility Framework (MEF) verfügbar, das im Paket NuGet.VisualStudio vorhanden ist (wechseln Sie zu den MEF-Diensten von NuGet). Es gibt neuere APIs, die für die Verwendung mit async Code konzipiert sind, die im Paket NuGet.VisualStudio.Contracts verfügbar sind, mithilfe der Visual Studio-Dienste IServiceBroker (wechseln Sie zu den Brokered Services von NuGet).
Paketversionen
Das Produkt von NuGet folgt der Version von Visual Studio, ist jedoch 11.0-Versionen zurück. Beispielsweise, entspricht NuGet 6.0 Visual Studio 2022 17.0, NuGet 5.11 entspricht Visual Studio 2019 16.11 usw.
Ab Visual Studio 17.1 entsprechen die Visual Studio-Erweiterungs-API-Pakete von NuGet der Version von Visual Studio, auf die die APIs ausgerichtet sind. Beispielsweise sollte NuGet.VisualStudio und NuGet.VisualStudio.Contracts-Paketversion 17.1.0 verwendet werden, wenn Ihre Erweiterung auf Visual Studio 17.1 und höher ausgerichtet ist. In Visual Studio 17.0 und früheren Versionen sind die Paketversionen von NuGet mit der Produktversion von NuGet identisch. Wenn Ihre Erweiterung beispielsweise auf Visual Studio 2022, Version 17.0, ausgerichtet ist, sollten Sie Version 6.0 der Visual Studio-Erweiterbarkeitspakete von NuGet verwenden.
NuGet Client SDK in Visual Studio-Erweiterungen
Nur die APIs in NuGet.VisualStudio und NuGet.VisualStudio.Contracts werden in Visual Studio-Erweiterungen unterstützt.
NuGet stellt für diese Assemblys Bindungsumleitungen bereit, so dass diese Assemblys nicht in Ihre Erweiterung aufgenommen werden müssen.
Die Verwendung von NuGet-Client-SDK-Paketen, z. B. NuGet.Protocol, wird in Visual Studio-Erweiterungen nicht unterstützt.
NuGet stellt keine Bindungsumleitungen für diese Assemblys bereit.
Weitere Informationen finden Sie in der NuGet-Client-SDK-Unterstützungsrichtlinie.

Verwenden von NuGet-Diensten
Warnung
Verwenden Sie neben den öffentlichen Schnittstellen in Ihrem Code keine weiteren Typen, und verweisen Sie auf keine anderen NuGet-Assemblys, wie NuGet.Protocol.dll, NuGet.Frameworks.dll, usw..
Um die Von uns vorgenommenen Zusagen der Abwärtskompatibilität zu maximieren, aber auch die Flexibilität zur Implementierung neuer Features, Leistungsverbesserungen und Bugfixes in Visual Studio bieten wir keine Unterstützung für das NuGet Client SDK, das in Visual Studio verwendet wird, und wir stellen keine Bindungsumleitungen in devenv.exe.config anderen Assemblys als unsere VS-Erweiterbarkeitsverträge bereit.
Wenn Sie eine neue NuGet-verwandte API in Visual Studio wünschen, suchen Sie bitte das Home-Repository von NuGet, und stimmen Sie allen vorhandenen Probleme zu, wenn Sie eine ähnliche finden. Wenn Sie eine vorhandene Feature-Anforderung zum Zustimmen nicht finden können, erstellen Sie eine.
Vermittelte Dienste
Installiere das
NuGet.VisualStudio.ContractsPaket in deinem Projekt, wieMicrosoft.VisualStudio.SDK.Verwenden Sie den
IAsyncServiceProviderService Broker von Visual Studio und nutzen Sie diese, um den Dienst von NuGet abzurufen. Beachten Sie, dassAsyncPackageerweitertIVsAsyncServiceProvider2wird, sodass Ihre Klasse, dieAsyncPackageimplementiert, alsIAsyncServiceProviderverwendet werden kann. Sehen Sie sich auch die Dokumente inIBrokeredServiceContainerundIServiceBrokeran// 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);Wenn Ihr Code den vermittelten Dienst von NuGet nicht mehr benötigt, löschen Sie ihn. Wenn Sie z. B. nur den vermittelten Dienst von NuGet während eines einzelnen Methodenaufrufs benötigen, können Sie ihn in eine C#
using-Anweisung einschließen:InstalledPackagesResult installedPackagesResult; using (nugetProjectService as IDisposable) { installedPackagesResult = await nugetProjectService.GetInstalledPackages(projectGuid, cancellationToken); }
MEF-Dienste
Installieren Sie das Paket
NuGet.VisualStudioin Ihrem Projekt, das die AssemblyNuGet.VisualStudio.dllenthält.In NuGet 5.11 und älter , wird nach Abschluss der Installation die Eigenschaft Interop-Typen einbetten des Assemblyverweises im Paket automatisch auf True festgelegt. Die Visual Studio 2022-Richtlinie für Einbettungs-Interoperabilitätstypen wurde geändert, sodass NuGet.VisualStudio-Paketversion 6.0.0 und höher dies nicht mehr verwenden.
Wenn Sie einen Dienst verwenden möchten, importieren Sie diesen über das Attribut „MEF-Import“ oder über den IComponentModel-Dienst.
//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();
Zu Referenzzwecken befindet sich der Quellcode für NuGet.VisualStudio im NuGet.Clients-Repository.
Grundlegendes zu .NET-Projektsystemen
Als SDK-Stilprojekte für .NET Core 1.0 hinzugefügt wurden, wurden sie so konzipiert, dass sie asynchroner als vorherige Visual Studio-Projektsysteme sind. Dies wirkt sich darauf aus, wie alle anderen Visual Studio-Komponenten, oder andere Komponenten wie NuGet, direkt damit interagieren. Dies ist besonders auffällig bei der Lösungslade und Projektlade, bei der Projekte einige Zeit nicht vollständig verfügbar sind, nachdem die älteren synchronen API-Benachrichtigungen von Visual Studio bereits ausgelöst wurden.
Beim Laden der Lösung ignoriert NuGet IVsSolutionEvents.OnAfterProjectLoad, um eine Verzögerung des synchronen Teils der Lösungslade zu vermeiden. NuGet synchronisiert seine internen Datenstrukturen, nachdem der synchrone Teil der Lösungsladevorgang abgeschlossen wurde. Dies gilt auch für Projekte im Nicht-SDK-Stil.
Selbst wenn alle IVsSolutionEvents.OnAfterSolutionLoad Ereignishandler fertig sind, signalisiert dies nur das Ende des synchronen Teils der Lösungslade. Der asynchrone Teil des Lösungsladevorgangs wird noch ausgeführt. Wenn Ihre Erweiterung NuGet-APIs wie GetInstalledPackagesAsync oder InstallPackage bald nach dem Laden von Projekten oder Lösungen aufruft, löst NuGet möglicherweise eine InvalidOperationException mit der Meldung „Fehler beim Vorgang als Details für Projekt {Projektname} konnte nicht geladen werden“.
Wenn eine Lösung mindestens ein SDK-Stilprojekt enthält, führt NuGet automatisch eine Wiederherstellung nach dem Laden der Lösung durch, und Sie sollten keine Nuget-APIs aufrufen, bis dies abgeschlossen ist. Sie können IVsNuGetProjectUpdateEvents verwenden, um eine Benachrichtigung zu erhalten, wenn die Wiederherstellung der Lösung oder eines bestimmten Projekts abgeschlossen ist. Wenn eine Lösung keine SDK-Stilprojekte enthält, wird die Wiederherstellung nicht automatisch geplant und kann erst erfolgen, wenn ein Build geplant ist.
Um zu ermitteln, ob ein Projekt den asynchronen Fluss (SDK-Stilprojekt) von NuGet verwendet, verwenden Sie PackageUtilities.IsCapabilityMatch mit dem Ausdruck CPS + PackageReference.
