FUSION_INSTALL_REFERENCE Structure

Represents a reference that an application makes to an assembly that the application has installed in the global assembly cache.

typedef struct _FUSION_INSTALL_REFERENCE_ {
    DWORD    cbSize,
    DWORD    dwFlags,
    GUID     guidScheme,
    LPCWSTR  szIdentifier,
    LPCWSTR  szNonCanonicalData
} FUSION_INSTALL_REFERENCE, *LPFUSION_INSTALL_REFERENCE;

Members

Member Description

cbSize

The size of the structure in bytes.

dwFlags

Reserved for future extensibility. This value must be 0 (zero).

guidScheme

The entity that adds the reference. This field can have one of the following values:

  • FUSION_REFCOUNT_MSI_GUID: The assembly is referenced by an application that was installed using the Microsoft Windows Installer. The szIdentifier field is set to MSI, and the szNonCanonicalData field is set to Windows Installer. This scheme is used for Windows side-by-side assemblies.

  • FUSION_REFCOUNT_UNINSTALL_SUBKEY_GUID: The assembly is referenced by an application that appears in the Add/Remove Programs interface. The szIdentifier field provides the token that registers the application with the Add/Remove Programs interface.

  • FUSION_REFCOUNT_FILEPATH_GUID: The assembly is referenced by an application that is represented by a file in the file system. The szIdentifier field provides the path to this file.

  • FUSION_REFCOUNT_OPAQUE_STRING_GUID: The assembly is referenced by an application that is represented only by an opaque string. The szIdentifier field provides this opaque string. The global assembly cache does not check for the existence of opaque references when you remove this value.

  • FUSION_REFCOUNT_OSINSTALL_GUID: This value is reserved.

szIdentifier

A unique string that identifies the application that installed the assembly in the global assembly cache. Its value depends upon the value of the guidScheme field.

szNonCanonicalData

A string that is understood only by the entity that adds the reference. The global assembly cache stores this string, but does not use it.
