At Microsoft s request, Wintellect has produced the Power Collections library to bring some of the C++ Standard Template Library s collection classes to the CLR programmer . This library is a set of collection classes that anyone can download and use free of charge . See http://Wintellect.com for details . These collection classes are generic themselves and make extensive use of generics . Table 12-1 shows a list of some of the collection classes you ll find in the Power Collections library .

If you extend the build process to create additional les you should always extend the clean process to remove these les. MSBuild will clean up all the les it generates, but you are responsible for cleaning yours. If you are implementing incremental building you should especially listen to this advice. This is because projects that are not properly cleaned may result is incorrect builds when building incrementally. We will talk more about incremental building in 6, Batching and Incremental Builds. In this example, I am manually deleting the created les but sometimes there is a better way. For C# or VB.NET projects there is a simple way to have your les automatically deleted for you. If you are creating les early in the build process, you can append les that should be deleted on clean by appending them to the FileWrites item. This is an item that the C# and VB.NET MSBuild les use to determine which les need to be deleted the next time the project is cleaned. The contents of this item are written into a le named $(MSBuildProjectFile).FileListAbsolute.txt in the intermediate output path folder. You can use this method only if you are appending the value to the FileWrites list before the Clean/ IncrementalClean target is executed and the le resides under the output path folder. This is a great way to make sure that generated code les are deleted at the appropriate time. This is discussed in more detail in 8, Practical Applications, Part 1.

where it came from. Scripts or con guration les that originated on the Internet will prompt you before you can run them, however. We think the default value of Restricted is a bit much, and frankly we re just not willing to get a code-signing certi cate just to run our own scripts, so even AllSigned is a bit much. In an environment that fully supports code-signing certi cates, and where you want to restrict the scripts that can be run to only those that are approved and signed, AllSigned makes sense. But for most SBS networks, we think RemoteSigned is a good compromise. To change the execution policy to RemoteSigned, follow these steps:

The following questions are intended to reinforce key information presented in this lesson. If you are unable to answer a question, review the lesson materials and try the question again. You can find answers to the questions in the Questions and Answers section at the end of this chapter. 1. Which action needs to be taken if you want to configure a DHCP server to update both A resource records and PTR resource records on behalf of a Windows NT 4 client a. No action is required. b. On the DNS tab of the DHCP server properties dialog box, select Dynamically Update DNS A And PTR Records For DHCP Clients That Do Not Request Updates. c. On the DNS tab of the DHCP server properties dialog box, select Always Dynamically Update DNS A And PTR Records. d. Register the client as a dynamic host with the DHCP server. 2. You have not modified the default settings for DNS on the DHCP client or server. Which of the following client record or records will be updated in DNS by the DHCP server (Assume that the clients are running Windows XP.) a. The PTR resource record b. The A resource record c. Both the PTR and A resource records d. Neither the PTR nor the A resource record 3. For a zone in which only secure dynamic updates are allowed, you have config ured your DHCP server to perform dynamic updates on behalf of Windows NT cli ents. All other dynamic DNS settings on the DHCP server have the default settings. After you migrate the clients to Windows XP, you find that their A resource records are no longer being updated. What is the most likely explanation for this problem

Microsoft Silverlight supports the use of dynamic languages, which are defined as programming languages that execute many features at run time that other languages, such as C#, execute at compile time. Such behaviors include extending objects and definitions, modifying the type system, and more. Dynamic languages are designed to be a simple approach that you can use to execute a run-evaluate-print loop with lots of trial and error as you develop, as opposed to the traditional model of code-compile-test-recompile. Silverlight supports three of the more popular dynamic languages: Ruby, Python, and Dynamic JavaScript. This book is written to the Silverlight 3 beta specification, which does not include a Microsoft Visual Studio 2008 project template, but the software development kit (SDK) does provide a tool, Chiron.exe, that you can use to work with dynamic languages. The dynamic language initiative from Microsoft is open source and is available on the CodePlex Web site at http://www.codeplex.com/sdlsdk. In this chapter, you explore building some basic applications for Silverlight with dynamic languages. This chapter isn t intended to be a learning tool for the languages themselves, but the programs are fairly straightforward, so you ll be able to figure out what they re doing even if you aren t an expert in the particular language. This chapter is intended solely as a primer in dynamic languages and how to use them in Silverlight. You spend most of your time in this chapter touring Visual Studio and learning how you can use it to create IronPython, IronRuby, and managed JavaScript applications in Silverlight, as well as how to integrate Chiron.exe into Visual Studio. Later on, you tour the famous Silverlight clock sample and find out how it was implemented in Ruby.

The other way is to open them directly, either from the Run menu or by using a Cmd or Windows PowerShell window. Our preference is to keep a Windows PowerShell window open on the desktop and use that. Table 17-1 has a list of the management consoles, along with a couple of keyboard shortcuts for control panel applications that are easier to get at from the command line.
