.NET Compact Framework 3.5 Data Driven Applications

Overview of this book

<p>The new .NET CF 3.5 framework provides enterprise application developers with a whole arsenal of possibilities at their disposal, but without proper guidance on developing performance-critical enterprise applications, it is easy to make the wrong design and technology decisions.<br /><br />This book guides you to build each part of a robust enterprise application by illustrating the .NET CF 3.5 framework with the help of real-world business applications. It will not only help you to master basic .NET CF skills, but also outlines the best methods, techniques, and tools available to create high-impact and performance-critical data-driven enterprise mobile applications. It provides a solid set of guidelines to aid .NET CF developers to understand how best to apply the features of the .NET CF 3.5 framework.<br /><br />The bulk of the book illustrates the basic concepts of .NET Compact 3.5 Framework programming by walking the reader through 3 different kinds of mobile applications:</p> <ul> <li>A thick-client mobile sales-force application</li> <li>A thin-client mobile dashboard and reporting application</li> <li>A customer support case management application</li> </ul> <p><br />Both the SQL Server Lite and Oracle Lite mobile databases are covered in detail, from data access to data synchronization. The book explains how device features such as Bluetooth, SMS, telephony, Infrared, and Windows Contacts can be accessed via .NET CF in a real-world example, namely the mobile sales-force application. It also explains.NET CF's GDI+ features that can be used to create rich charts and reports. You learn to synchronize the mobile application with remote datasources and communicate via web services and WCF services. The book outlines performance optimization and memory management techniques on the mobile platform. It also outlines the tools and techniques available for testing, performance-tuning, deploying and debugging .NET CF enterprise applications (including Power Toys for .NET Compact Framework 3.5 from Microsoft).</p>

Preface

Using the CLR Profiler tool


The CLR Profiler tool is another powerful tool that allows you to view the memory allocation profile of your application. It provides the details of how your application is allocating and using managed objects. You can look at the heap at various points in time and even walk through the method calls involved in allocating each managed object.

While the Remote Performance Monitor tool is useful in detecting memory leaks, the CLR Profiler tool allows you to zoom in on the particular method and line of code that caused it. To describe the features of the CLR Profiler tool, we will run it on another sample application—one with visibly bad performance.

A sample application with bad performance

Let's assume we have an application that needs to populate a DataGrid control with a list of Customer objects. Each Customer object holds a Product code (the product he or she is interested in), which is used to fetch the actual product name from a hash table.
