you need pass name of provider declared in membership section of web.config when create instance of custommembersipuser. not recommanded hardcode value in custommembershipprovider, instead use private field receives value when custommembershipprovider.initialize method called.
for example
public class custommembershipprovider: membershipprovider { private providername = null; ... public override void initialize(string name, namevaluecollection config) { providername = name; // friendly name of provider ... } public override membershipuser testcreateuser(string username, bool userisonline) { custommembershipuser membershipuser = new custommembershipuser(providername, username, guid.parse(userid.tostring()), email, passwordquestion, comment, isapproved, islockedout, creationdate, lastlogindate, lastactivitydate, lastpasswordchangeddate, lastlockedoutdate, "ss"); ... } } you can see similar more detailed example on msdn.
