Referencing the CU Library

The ArcFM Desktop SDK includes a LoadLibrary method that returns a reference to the CU library. In most cases, however, it's more efficient for custom programs to store a reference to the CuLibraryExtension. If the extension does not already contain a local reference to the library, it will call LoadLibrary(). Consequently, you should leverage Esri's extension manager to get a reference to the library's extension:

Create a method or a class property that returns a CuLibrary object.
Include a get accessor that creates an instance of Esri's extension manager.
Use Esri's extension manager to locate the CuLibraryExtension.
Return the CuLibrary stored in the extension.

        // If it still equals null, no extension could be found.
