I use LINQPad all the time at, both for experimenting with C#, and for building and testing Linq queries before I import them in our projects.
As an example, I recently wrote a few scripts for fetching some data from a database, and reformatting it into JSON data which we will use as dummy-data for testing. This will not be a part of our finished project, but it’s still nice to have the script visible in Visual Studio, even if I only run it through LINQPad .
The following are a couple of tips I’ve found useful when working with .linq-files in or from within Visual Studio.
