title: value from database computed property is Null in codefluent entity property
body: <p>My MS SQL 2014 database table has a computed property column which uses a database function.  Using SQL Server Management Studio, a query against the table lists the computed property values as expected.</p>
  
  <p>The Codefluent model created via the import wizard shows the Entity with the computed column as a property.  The underlying .cpf file defines the property with "d3p1:compute=" and the list of parameters that are used by the database function.</p>
  
  <p>When an entity or the collection of entities is loaded, the properties which are used in the computed property have values, yet the computed property has a value of nothing/null.</p>
  
  <p>How do I get Codefluent to read the computed value from the database table and have the value included in the entity's properties?</p>
