Specifies the version number of an exported type library.
Assembly: mscorlib (in mscorlib.dll)
Thetype exposes the following members.
|Equals||Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Returns the hash code for this instance. (Inherited from Attribute.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|IsDefaultAttribute||When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)|
|Match||When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|_Attribute.GetIDsOfNames||Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)|
|_Attribute.GetTypeInfo||Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)|
|_Attribute.GetTypeInfoCount||Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)|
|_Attribute.Invoke||Provides access to properties and methods exposed by an object. (Inherited from Attribute.)|
You can apply this attribute to assemblies.
By default, the Tlbexp.exe (Type Library Exporter) generates a type library version from the first two numbers of an assembly version. For example, Tlb.exe exports assembly version 1.2.5000.0 as a type library version 1.2, eliminating the build and revision numbers of the assembly. If this behavior is undesirable, you can control the generation of the type library number explicitly by applying the .
It is useful to control the generation of a type library version explicitly when two assembly versions produce the same type library version. For example, assembly version 188.8.131.52 and assembly version 1.2.500.0 both produce a type library version of 1.2, which can cause problems when you uninstall one of the assemblies. To differentiate the type library versions, you can force the second assembly (version 1.2.500.0) to produce a type library version of 1.25.
