ASP.NET MVC3 Custom Membership Provider - The membership provider name specified is invalid.
- by David Lively
I'm implementing a custom membership provider, and everything seems to go swimmingly until I create a MembershipUser object. At that point, I receive the error:
The membership provider name specified
is invalid. Parameter name:
providerName
In web.config the membership key is
<membership defaultProvider="MembersProvider">
<providers>
<clear/>
<add name="MembersProvider" type="Members.Providers.MembersProvider" connectionStringName="ApplicationServices"
enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false"
maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10"
applicationName="DeviceDatabase" />
</providers>
</membership>
When creating the MembershipUser object from my custom User class:
public static MembershipUser ToMembershipUser(User user)
{
MembershipUser member = new MembershipUser
("MembersProvider"
, user.Name
, user.Id
, user.EmailAddress
, user.PasswordQuestion
, user.Comment
, user.IsApproved
, user.IsLockedOut
, user.DateCreated
, user.LastLoginDate ?? DateTime.MinValue
, user.LastActivityDate ?? DateTime.MinValue
, user.LastPasswordChangedDate ?? DateTime.MinValue
, user.LastLockoutDate ?? DateTime.MinValue
);
return member;
}
(I realize I could probably just inherit my User class from MembershipUser, but it's already part of an existing class hierarchy. I honestly think this is the first time I've encountered a legitimate need for for multiple inheritance!)
My feeling is that the new MembershipUser(...) providerName parameter is supposed to match what's set in web.config, but, since they match already, I'm at a loss as to how to proceed.
Is there a convenient way to get the name of the active membership provider in code?
I'm starting to think that using the built-in membership system is overkill and more trouble than it's worth.
Edit
Not sure if it's relevant, but the custom membership provider class is in a class library, not the main WAP project.
Update
Here's the contents of the System.Web.Security.Membership.Provider object as show in the VS2010 command window:
>eval System.Web.Security.Membership.Provider
{Members.Providers.MembersProvider}
[Members.Providers.MembersProvider]: {Members.Providers.MembersProvider}
base {System.Configuration.Provider.ProviderBase}: {Members.Providers.MembersProvider}
ApplicationName: null
EnablePasswordReset: true
EnablePasswordRetrieval: false
MaxInvalidPasswordAttempts: 5
MinRequiredNonAlphanumericCharacters: 0
MinRequiredPasswordLength: 6
PasswordAttemptWindow: 10
