70-518試験無料問題集「Microsoft PRO: Design & Develop Wndws Apps Using MS .NET Framework 4 認定」
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 a Windows Presentation Foundation (WPF) application. The WPF application contains code that will be executed by both full trust callers and partial trust callers.
The WPF application code does not have the AllowPartialTrustCallers attribute set.
You have the following requirements:
- The application security settings must allow partial trust callers to create and write
to a file.
- Users must have access only to files that they create and not to files created by other users.
You need to recommend a location for storing each user's files.

You are designing a distributed application that will be deployed to 5,000 users worldwide. Servers on five continents will host the Web services and the Microsoft SQL Server 2008 databases that support the application.
You have the following requirements:
Collect information about all errors associated with the application.
Store and view all error information in a centralized location.
Minimize the network bandwidth required for the transfer of error information.
You need to recommend a strategy for reporting error information.

You are upgrading a stand-alone Windows Presentation Foundation (WPF) application and an XAML browser application (XBAP) to Microsoft .NET Framework 4.
You plan to add .NET 4 types and members to both applications.
Both applications consume a common utility assembly that modifies files on a local file system. The utility assembly requires full trust.
You need to ensure that both applications can use the common utility assembly without any security-related exceptions.

You are developing an application by using Microsoft .NET Framework 4 and Microsoft
Visual Studio 2010.
The application contains a grid that displays customer data stored in a database table.
Users report that the grid takes a long time to display.
You plan to implement data caching to improve loading time for the grid.
You need to ensure that the cached data expires when the customer data is updated.
