ClearScript

ClearScript is a mash-up from Google's V8 engine, Microsoft's JScript, and VBScript, adding a scripting language interpreter to any .NET-based website, desktop, or mobile application.

This means developers can use JavaScript or VBScript on top of C# or ASP.NET to have more control over the runtime code, interactions, and behavior.

ClearScript comes with full support for generic types, objects, and methods.

What is new in this release:

• Fixed unnecessary assembly table construction.

What is new in version 5.4.2:

• Switched assembly targets to .NET 4 Client Profile.
• Added tests for bug fixes and new APIs.
• Updated ClearScriptBenchmarks to use SunSpider 1.0.2.
• Host methods and delegates in V8ScriptEngine now support toFunction(), which creates a native JavaScript function wrapper.
• Fixed syntax error reporting in nested WindowsScriptEngine invocations.
• Added defensive code to tolerate IProcessDebugManager::AddApplication() failure.
