Raudus is a web-framework and component set for Delphi and Lazarus, that allow create Rich Internet Applications (RIA). The development process is very similar to desktop applications development. Using Raudus you create both client-side and server-side at the same time. UI components are shown at client, event handlers are executed at server. Raudus is well suitable for database applications.

LINQPad is also a great way to learn LINQ: it comes loaded with 500 examples from the book, C# 5.0 in a Nutshell. There's no better way to experience the coolness of LINQ and functional programming. Querying is merely a special case of using LINQPad. More generally, LINQPad is a C#/VB/F# scratchpad that instantly executes any expression, statement block or program with rich output formatting and a wealth of features that "just work". Put an end to those hundreds of Visual Studio Console projects cluttering your source folder and join the revolution of LINQPad scripters, testers, and incremental developers. Reference your own assemblies and NuGet packages. Script in your favorite .NET language with optional autocompletion and the entire .NET Framework at your fingertips. Experience the magic of dynamic development and instant feedback in the ultimate programmer's playground!

Spring.NET Social helps you to simplify authentication (OAuth) and API binding with Software-as-a-Service (SaaS) providers such as Facebook and Twitter. Spring.NET Social makes it easy to add support for service providers that are not already supported by the framework. If you review the existing client projects, such as Twitter, Dropbox, LinkedIn and Facebook, you will discover they are implemented in a consistent manner and they apply a set of well-defined extension points.

OrangeUI is a cross-VCL and FMX framework skin engine, VCL Edition supports the latest version of D7 ~ XE, FMX edition Given XE2 ~ XE7 these transitions have become mobile development version, unstable, it only supports XE5UP2 above and, if after XE6 out performance is more good, then will only support XE7.

Oxygene and RemObjects C# (formerly code-named Hydrogene) are a modern development tool stack for creating applications for all three major development platforms: .NET, Cocoa and Java.

Leverage the same language skill set, no matter what platform(s) you are developing for, without losing the benefit of working natively and directly with the underlying platforms — be it the .NET Framework, the Java and Android Runtime Libraries, or the Cocoa and Cocoa Touch Frameworks.
