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.)

You are designing an n-tier solution that includes a Windows Presentation Foundation (WPF) client application. The WPF application connects to a middle-tier server that runs the data access layer.
The data access layer connects to a Microsoft SQL Server 2008 database and to a mainframe-based database.
The mainframe-based database will be replaced in one year.
You have the following requirements:
---
Centrally manage all database connections.
Minimize changes to the code base when the database is replaced.
Ensure that the WPF application will not need to be redeployed when the database
is replaced.

You are designing a new feature for an existing Windows Forms application by using Microsoft .NET Framework 4.
The application contains multiple forms that are loaded into a parent Multiple Document Interface (MDI) form. Your company policy does not allow the use of third-party controls.
You need to ensure that the new feature meets the following requirements:
- It provides a three-dimensional scale model.
- It allows users to change the colors of the model and communicates the color
selections back to the application.
- It allows the model to scale, based on the user's client computer display resolution.
- It is a child form in the MDI application.

You are developing a Windows application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.
The application will consume a Windows Communication Foundation (WCF) service. The WCF service will provide data to the application.
You plan to use the ADO.NET Entity Framework to create a data model that will be used by the application.
Another development team makes changes to the WCF service data contract.
You need to ensure that changes made to the WCF service data contract do not require the application to be recompiled.
