When using this code to get an instance of IEdmVault object, I am getting a compiler error (C#). From the API Fundamentals book (Solidworks 2011), page 62, It seems that this is the best practice to keep connections to a minimum.

So instead of using:

IEdmVault5 vault = new EdmVault5();

The books suggests using:

IEdmVault5 vault = EdmVaultSingleton.Instance;

But it doesn't compile. Am I missing a reference?
