LINQPad (http://www.linqpad.net/ ) is a software utility for .NET that allows you to quickly and interactively test out C#, VB.NET and F# code without the need for an IDE. We highly recommend that you use this tool (free edition exists) for experiments and learning.

QuickOPC works well with LINQPad. We have made some special tweaks for it as well, e.g. to ensure a proper expandable display of all types in LINQPad.

QuickOPC standalone installer ships with examples for LINQPad; see the Examples section in this document for details. The NuGet packages include the LINQPad examples as well.
