IHostAssemblyManager::GetNonHostStoreAssemblies Method

Gets an interface pointer to an ICLRAssemblyReferenceList that represents the list of assemblies that the host expects the common language runtime (CLR) to load.


HRESULT GetNonHostStoreAssemblies (  
    [out] ICLRAssemblyReferenceList **ppReferenceList  


[out] A pointer to the address of an ICLRAssemblyReferenceList that contains a list of references to assemblies that the host expects the CLR to load.

Return Value

HRESULT Description
S_OK GetNonHostStoreAssemblies returned successfully.
HOST_E_CLRNOTAVAILABLE The CLR has not been loaded into a process, or the CLR is in a state in which it cannot run managed code or process the call successfully.
HOST_E_TIMEOUT The call timed out.
HOST_E_NOT_OWNER The caller does not own the lock.
HOST_E_ABANDONED An event was canceled while a blocked thread or fiber was waiting on it.
E_FAIL An unknown catastrophic failure occurred. When a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.
E_OUTOFMEMORY Not enough memory was available to create the list of references for the requested ICLRAssemblyReferenceList.


The CLR resolves references using the following set of guidelines:

  • First, it consults the list of assembly references returned by GetNonHostStoreAssemblies.

  • If the assembly appears in the list, the CLR binds to it normally.

  • If the assembly does not appear in the list and the host has provided an implementation of IHostAssemblyStore, the CLR calls IHostAssemblyStore::ProvideAssembly to allow the host to supply the assembly to bind to.

  • Otherwise, the CLR fails to bind to the assembly.

If the host sets ppReferenceList to null, the CLR first probes the global assembly cache, calls ProvideAssembly, and then probes the application base to resolve an assembly reference.


Upon initialization, the CLR calls GetNonHostStoreAssemblies only once. The method is not called again.
