Accessing EF Business Objects from a UI Project

To access an Entity Framework Business Object project from a User Interface project (such as WPF, Windows Forms, Web Forms), just add the Entity Framework Business Object to your solution, or you can add a reference to the Entity Framework Business Object assembly.

Afterwards, make sure you copy both the <databases> node and the <connectionStrings> node from your Entity Framework Business Object project's app.config into your UI project's application config file (app.config or web.config).

For example:

<databases>

    <add key="Northwind\Connection" value="server=(local);uid=sa;pwd=;database=NorthWindEF;" />

<add key="Northwind\DataAccessClass" value="DataAccessSql" />

    <add key="EntityDataModelContainer\DataAccessClass" value="DataAccessSqlEF" />

</databases>

<connectionStrings>

    <add name="EntityDataModelContainer" connectionString="metadata=res://*/EntityDataModel.csdl|res://*/EntityDataModel.ssdl|res://*/EntityDataModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=(local);Initial Catalog=NorthwindEF;Integrated Security=True;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />

</connectionStrings>
