Hello Umbracoland

I want to move my members from the umbraco database to another database, where the members will be stored. I need to implement my own membership provider, as I want to hash everything we know about our users.

Untill now I have just been trying to very simple membership provider to store some mock users in a local database. I have so far based my solution on an earlier post (https://our.umbraco.com/forum/developers/extending-umbraco/74219-custom-membership-provider/), however I am using the Entity framework instead.

So far I have

• Created a custom membership provider inheriting from the standard membership provider.
• Made a member repository with methods for interactions with the database.
• Made a model class with an entity framework class.
• Replaced the default umbraco membership provider with my custom membership provider in the Web.config file.

When I try to create a member in the backoffice -> Members -> Members -> create I get an error message. To me it seems that Umbraco doesn't recognize my membership provider. I hope someone out there is able to helpt me, I've been stuck with this for quite some time now.

Error message

System.NullReferenceException: Object reference not set to an instance of an object.
