title: Map collection of timespan with Fluent NHibernate
body: <p>I have an object that contains a collection of <code>TimeSpan</code> like <code>Note.Reminders</code>, where reminders is <code>List&lt;TimeSpan&gt;</code>. How to I map this using <a href="http://fluentnhibernate.org/" rel="nofollow noreferrer">Fluent NHibernate</a>?</p>
  
  <p>Currently I have mapped it as <code>m.HasMany(c=&gt;c.Reminders).Access.CamelCaseField()</code>.</p>
  
  <p>But it complains that it can not find a mapping for type <code>TimeSpan</code>.</p>
