CMSCategoriesDataContext db = new CMSCategoriesDataContext();

var cnt = from c in

db.Categories.Single(c => c.CategoryName == "Apparel")

select c;

The above coding does not working to me. it shows the error as following:

"Could not find an implementation of the query pattern for source type 'CMSCategory.Category'. 'Select' not found.

its based on ur query. Then y should i get this error message. How can I overcome this? Pls tell me the solution.

I've come up on this page by accident - very good tutorial! List View control is very powerful.

re: Extension methods in C# and .NET Framework 3.5

Just because YOU CAN doesn't mean it is necessarily a good thing to do. Extending a class's API with additional signatures means diverting the original designer's intent with your own custom design, additionally polluting the namespace. Case in point: the DateTime class. It is well known to all that it doesn't have much information of month names. That's because it is found in GregorianCalendar, when the culture info is United States and using the English language. So, getting today's month name is a bit cumbersome, having to use many separate classes just to get that info. Ever tried populating a dropdown listbox with english month names, January to December? not so obvious... So, the developer might be tempted on extending the DateTime class with MonthNameArray that returns string[] (an array of strings). Fine. That was in one departmental project. In another departmental project, they might be doing their own custom extensions to the DateTime class. Then, developers migrate from one project to another, and bring with them their own personal extensions, and add them again to the new project's DateTime class. OK, now, pressing the dot shows IntelliSense retrieving HUNDREDS of new methods, some may be named PrintMMDDYYYY, PrintLongMonthDayLongYear, etc etc. Just imagine when a manager wants to merge these two apps. You might just have two separate methods, similarly named, that might just do almost the same thing. Or, what about when you "reuse" some code, but this code is invoking methodds that don't exist in your DateTime class... Guess what: you will be forced to extend your DateTime class with their extensions. This is a new feature that is being allowed by the compiler. People think it is cool. Great. Now the gates are open. Before going gung-ho on these extensions, consult with other developers that have used them in other programming environments, and ask them about the pros and cons, specially after a couple of years on a project. You will see there is a price in future maintenability. My advice: add extensions to a class only when there is no other way to do what you want to do. If there is a different pattern or helper class that achieves the same goal, go for that solution. If you inherited a DLL-ized component for which you do not have the source code, and the API framework that you are using requires that this DLL-ized component, in order to be usable, needs to understand the message being sent to it named "DisplayValueName" and it takes a signature of "string, int", then, go ahead, and extend that DLL-ized component with public void DisplayValueName (string param1, string param2)
