IHostAssemblyStore Interface

Provides methods that allow a host to load assemblies and modules independently of the common language runtime (CLR).

interface IHostAssemblyStore: IUnknown {
    HRESULT ProvideAssembly (
        [in]  AssemblyBindInfo *pBindInfo,
        [out] UINT64           *pAssemblyId,
        [out] UINT64           *pHostContext,
        [out] IStream          **ppStmAssemblyImage,
        [out] IStream          **ppStmPDB
    );
    HRESULT ProvideModule (
        [in]  ModuleBindInfo   *pBindInfo,
        [out] DWORD            *pdwModuleId,
        [out] IStream          **ppStmModuleImage,
        [out] IStream          **ppStmPDB
    );
};

Methods

Method	Description
IHostAssemblyStore::ProvideAssembly Method	Gets a reference to an assembly that is not referenced by the ICLRAssemblyReferenceList returned from a call to IHostAssemblyManager::GetNonHostStoreAssemblies.
IHostAssemblyStore::ProvideModule Method	Resolves a module within an assembly or a linked (not embedded) resource file.

Remarks

IHostAssemblyStore provides a way for a host to load assemblies efficiently based on assembly identity. The host loads assemblies by returning IStream instances that point directly at the bytes.

The CLR determines whether a host has implemented IHostAssemblyStore by calling IHostAssemblyManager::GetNonHostAssemblyStores upon initialization. This allows the host, for example, to control binding to user assemblies, but to rely on the runtime to bind to .NET Framework assemblies.

Note:
In providing an implementation of IHostAssemblyStore, the host specifies its intent to resolve all assemblies that are not referenced by the ICLRAssemblyReferenceList returned from IHostAssemblyManager::GetNonHostStoreAssemblies.

Note:
The .NET Framework version 2.0 does not provide a way for the host to load the native image of an assembly, as provided by the Native Image Generator (Ngen.exe) utility.
