LINQPad is an advanced utility for .NET programmers designed to facilitate experimentation and interactive querying. While originally developed to execute LINQ queries, it has grown into a versatile tool for writing and executing C#, F#, and VB code snippets. LINQPad features a rich query editor with support for autocompletion, syntax highlighting, and debugging, making it a powerful scratchpad for all forms of .NET development. Users can interact directly with their databases using LINQ, visualize query results, and even use LINQPad as a testing ground for more complex .NET code, without the need for a full development environment.
