LINQ is certainly extraordinarily useful. It brings the power of query expressions to C#, allowing an easy way of getting the data you need from a variety of data sources. Up to now, there hasn't been a VS debugger for LINQ that gives you the means to visualise the data at every point in the chain. Michael Sorens, a keen LINQ user, describes a third-party tool that now promises to make using LINQ something we can all participate in.… Read more

T4 usually stays behind the scenes in Visual Studio, but if you find that you have a good reason to write similar code over and over again, or use a lot of copy and paste, then it could be that you have a specific use for T4. There are times when it can be useful for generating code templates but it is versatile to provide a solution for a number of programming headaches.… Read more
