LINQPad Editions

There are four different versions of LINQPad to choose from where each version offers additional useful functionality.

My recommendation is Premium because it's still extremely affordable and is required to use the built-in debugger and AI coding tools. In a pinch and if there's truly a constraint the Developer version will also suffice as it includes the NuGet Package Manager which is really something that is needed to be a useful addition to the developer.

The free version is quite useful as an analog to a user with a paid license. For instance, using LINQPad scripts on another machines or servers where LINQPad is not licensed.

LINQPad Free executes all scripts as expected including restoring NuGet packages. The bundled tool lprun.exe is a utility to run .linq scripts in a headless environment (think scheduled tasks or automation) and it's completely free as well.
