Transactions can provide essential support for ensuring that business rules are not violated and that data consistency is maintained. A transaction ensures that a set of related tasks either succeed or fail as a unit. You can use transactions to maintain consistency between a local database and other resources, including Message Queuing queues. For smart client applications that need to work with offline cached data when network connectivity is not available, you should queue the transactional data and synchronize it with the server when network connectivity is available. You should avoid using distributed transactions involving resources located on the network, as these scenarios may lead to performance problems due to varying network and resource response times. If your application needs to involve a networklocated resource in a transaction, you should consider using compensating transactions, which allow your application to cancel a previous request when a local transaction fails. Though compensating transactions may not be suitable for all situations, they allow your application to interact with network resources within the context of a transaction in a loosely coupled manner, reducing the chance that a resource not under the control of the local computer can adversely affect the performance of your application.

The first way to extend LINQ is to create additional query operators. You can use this technique to overcome the limitations that you may run into when working with the standard query operators. We ll lead you through examples that will show you how to create additional operators that supplement the standard operators. We ll also demonstrate how custom query operators may be used to enrich your LINQ queries with domain-specific processing.

Since we re looking at how you can overcome limitations of the standard query operators, the best example to look at is a custom implementation of the Sum operator. When using the standard query operators in his code, a C# developer named Troy Magennis noticed some limitations (see http://aspiring-technology.com/ blogs/troym/archive/2006/10/06/24.aspx). One of the limitations comes from the Sum query operator. There is a high chance for overflow when working with big numbers and the variant of Sum that operates on a sequence of integers. The following simple piece of code demonstrates this problem:

Enumerable.Sum(new int[] {int.MaxValue, 1});

Understandably, this code yields an OverflowException with the message Arithmetic operation resulted in an overflow. 1 The problem is that the sum of two integers can be too big to fit in an int (System.Int32) object. This is why Troy wrote LongSum, which returns a long (System.Int64) object instead of an int object, as with Sum. Let s re-create the LongSum operator together. As you saw when we introduced the standard query operators in chapter 3, they consist of extension methods for the IEnumerable<T> type. Listing 12.1 shows how the Sum operator for int comes out of the box in the System.Linq.Enumerable class.

namespace System.Linq { public static class Enumerable {

C# statements can execute in either checked or unchecked context, depending on the use of the checked or unchecked keywords. In a checked context, arithmetic overflow raises an exception. In an unchecked context, arithmetic overflow is ignored and the result is truncated. The Sum operator is implemented using the checked keyword, hence the OverflowException.

The Switch construct acts as a specialized kind of logical comparison. You start with a single variable or property, and you ask the shell to compare its contents to a wide range of possible values. The shell will execute a block of commands for each match that it finds. Here s an example that translates a numeric printer status code into a humanreadable status message:

... public static int Sum(this IEnumerable<int> source) { if (source == null) throw new ArgumentNullException("source"); int sum = 0; checked { foreach (int v in source) sum += v; } return sum; } public static int Sum(this IEnumerable<int > source) { if (source == null) throw new ArgumentNullException("source"); int sum = 0; checked { foreach (int v in source) if (v != null) sum += v; } return sum; } public static int Sum<T>(this IEnumerable<T> source, Func<T, int> selector) { return Enumerable.Sum(Enumerable.Select(source, selector)); } public static int Sum<T>(this IEnumerable<T> source, Func<T, int > selector) { return Enumerable.Sum(Enumerable.Select(source, selector)); } ... } }

Fast application startup time allows the user to begin interacting with the application almost immediately, giving the user an immediate and favorable perception of your application s performance and usability When an application starts, first the CLR is loaded, then your application s main assembly, followed by all of the assemblies that are required to resolve the types of objects referenced from your application s main form The CLR does not load all of the dependent assemblies at this stage; it loads only the assemblies that contain the type definitions for the member variables on your main form class Once these assemblies are loaded, the just-in-time (JIT) compiler compiles the code for the methods as they are run, starting with the Main method Again, the JIT compiler does not compile all of the code in your assembly Instead, the code is compiled as required on a per method basis.
