NET Compiler Platform (“Roslyn”) NuGet package into your ASP.NET application. Install the new Code DOM Providers for.NET Compiler Platform (“Roslyn”) End User Preview on your developer machine (where you use Visual Studio or build your application's project file). To properly install the Roslyn compiler in ASP.NET we need to do the following two things: Installation Procedure for Roslyn compiler Thanks to the newly accessible semantic information, Roslyn includes a number of new Refactoring and has vastly improved the existing ones (especially Rename). Roslyn exposes a simple extensibility model that lets you create your own warnings or refactorings that integrate with Visual Studio. This makes it easy to build many tools to analyze or modify source code. Roslyn allows us to easily write C# (or VB) code that parses a source file and rewrites the code. The Visual Studio templates available for both Visual Basic and C# installed with the Community Technology Preview are Console Applications, Code Issues, Code Refactoring and Completion Provider. The Roslyn compiler fetches information regarding the entire source code like what and which type of elements are present in the code, what the real meanings of those elements are, how they are communicated and related to the each other and the IL emitting (executable code). The C# and VB teams got together and rewrote the compilers and language services in managed code, replacing a horrible mess of C++ code (with some managed code) that had mutated over the past ten years into a complex and difficult-to-modify code base.

Net Compiler Platform, also known as 'Roslyn', is the most awaited project of Microsoft. That means that developers can clone the company's compiler for C# projects and add their own features, as well as suggest new features for Microsoft to implement in the compiler itself. The Roslyn team started by re-implementing the compiler in C#.
