Question

I have a custom asp.net membership class I am building where I have a helper function that the
GetUser() method uses to convert the values from my database into a System.Web.Security.MembershipUser object.

private MembershipUser _converToMembershipUser(MembershipDBModel member)
    {

        System.Web.Security.MembershipUser membershipUser = new System.Web.Security.MembershipUser(
        this.Name,
        member.UserName,
        member.UserID.ToString(),
        member.Email,
        member.PasswordQuestion,
        member.Comment,
        member.IsApproved,
        member.IsLockedOut,
        member.CreationDate,
        member.LastLoginDate,
        member.LastActivityDate,
        member.LastPasswordChangedDate,
        member.LastLockedOutDate);

        return membershipUser;
    }

This is the error that I keep getting when the above method is being called. I have not idea how to get around this so any suggestion is very welcome.

Error: “The given assembly name or codebase was invalid”

Your type attribute:

type="TMTechMembershipProvider.TempMembershipProvider" 

Your type attribute in your commented line:

type="TMTechMembershipProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=cbae438f5bab0724"

Your comment:

i tend to agree but this is needle in haystack. This is what I thought the Fusion Log Viewer was for to help identify what is failing to load.

sry, but lol 🙂

Update 1: re the comment:

Just found it funny, couldn’t resist. Meant no harm and was not imply anything with it, we’ve all been there.

Now on a more serious note, it still seems an issue with specifically that line.

Let’s compare it with the type line of the asp.net provider:

type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"

[Provider class (including the namespace)], [dll], [Version], ...

It seems you are missing either the class or the dll. Hoping that solves it, good luck.
