This will use the logged in machine credential for all the authentication with virtual clusters. For example, if the windows machine running this library is running under PHX\johndoe, that will be the credential used for virtual cluster authentication. Using default credentials gives the advantage of not having to encode the user credentials. Also, you can set the virtual cluster name and proxy using the corresponding parameters.

public delegate void SetDefaultCredentials(
	string vcName,
	string proxy
)

Public Delegate Sub SetDefaultCredentials ( _
	vcName As String, _
	proxy As String _
)

public delegate void SetDefaultCredentials(
	String^ vcName, 
	String^ proxy
)
