While I will be covering the details of performing LINQ to SQL queries in detail in subsequent LINQ to SQL chapters, I want to give you a glimpse of how to perform the rudimentary database operations without the complexity of the complications. These examples are meant to merely demonstrate the basic concepts. As such, they will not include error checking or exception handling.
For example, since many of the basic operations I will discuss make changes to the database, those that make changes should detect and resolve concurrency conflicts. But, for the sake of simplicity, these examples will not demonstrate these principles. However, in Chapter 17, I will discuss concurrency conflict detection and resolution.
