    <p>I am trying to learn Nhibernate using fluent nhibernate mappings and i have created a small test app. Below is the code:</p> <p>UserClass:</p> <pre><code>public class User { public string UserName { get; set; } public string Password { get; set; } public string Role { get; set; } public string Email { get; set; } public DateTime JoinDate { get; set; } } </code></pre> <p>User Map Class:</p> <pre><code>public class UserMapping: ClassMap&lt;User&gt; { public UserMapping() { WithTable("UserT"); Not.LazyLoad(); Id(u =&gt; u.UserName); Map(u =&gt; u.Password); Map(u =&gt; u.Role); Map(u =&gt; u.Email); Map(u =&gt; u.JoinDate); } } </code></pre> <p>DAL User Class:</p> <pre><code>public class DALUser { public User GetUserByUserName(string userName) { ISessionFactory sessionFactory = Fluently.Configure() .Database(MsSqlConfiguration.MsSql2005.ConnectionString(c =&gt; c.Server("ServerName").Database("DBName").TrustedConnection())) .Mappings(m =&gt; m.FluentMappings.AddFromAssemblyOf&lt;UserMapping&gt;()).BuildSessionFactory(); ISession session = sessionFactory.OpenSession(); return session.Get&lt;User&gt;(userName); } } </code></pre> <p>Nunit Test Class:</p> <pre><code>[TestFixture] public class UserTest { [Test] public void CanGetUserByUserName() { DALUser user1 = new DALUser(); Assert.AreEqual("testUser", user1.GetUserByUserName("testUser").UserName); } } </code></pre> <p>When i try to run the test class i get the following error :Object reference not set to an instance of an object. I have placed a breakpoint in the GetUserByUserName method and noticed that its returning a null user. But i am not able to figure out why this is happening. Can anyone help me?</p>

    1. COIf you query the database with SELECT * FROM UserT WHERE UserName = 'testUser', what is the result?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
