database system without duplicating data accesslogic.
You need to recommend a data access technology.
What should you recommend?

A) LINQ to Entities
B) ADO.NET using DataSet objects and SqlDataReader objects
C) ADO.NET using DataSet objects and SqIDataAdapter objects
D) LINQ to SQL

2. You are designing a .NET Framework 4 solution that includes a Windows Presentation Foundation (WPF) application, a Windows service, and a private assembly shared by the WPF application and by the Windows service.
The solution stores data in a local Microsoft SQL Server Compact 3.5 database. The WPF application and Windows service will each access the database directly. The solution will be installed by using Windows Installer.
You have the following requirements:
- The installer must allow users to specify the installation folders for the WPF application and for the database. - The solution must support the deployment of updates to the WPF application without restarting the Windows service.
You need to recommend an approach for installing the solution.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

A) In the installer, create a registry key that stores the WPF application installation path.
B) Install the Windows service to the same folder as the WPF application.
C) In the installer, set an environment variable that defines the database installation path.
D) Install the Windows service to a different folder from the WPF application.

3. You are designing an application by using Windows Presentation Foundation (WPF) and Microsoft .NET Framework 4.
