c＃身份userManager.FindAsync无效的UserId

Question

I am using Asp.net Identity to authorize logins. I can register accounts, but I cannot login with them. I am getting 500 error (Invalid Column Name) when this function is called.

    try
    {
         user = await userManager.FindAsync(context.UserName, 
            context.Password);

    }catch(Exception e)
    {
        //Invalid column name 'UserId'.
    }

Also, I manually created the database using this link..

How do I create the asp.net Identity tables manually with migrations?

I changed the UserId field in a test database to match your AspNetUserClaims table. Normally, the field is named UserId, rather than User_Id like yours is. When I made this small change and tried to get a token from the project, the result was an invalid column name 'UserId'.

To solve this alter your AspNetUserClaims table to remove the underscore from that field. It should then hopefully work. Basically your FindAsync is failing to find that column when it goes to fetch the user and all the related tables.
