Prerelease Software Downloads
Prerelease software enable us to provide early and frequent builds of our products under development. It enables us to collect your valuable, real-world feedback throughout the product development cycle, so that we can ship higher quality products. Sharing prerelease software with you help us innovate and deliver the products we know that you will continue to value and appreciate.
- Release Candidate (RC) software is a version of the product (usually the most recent) that is deemed complete and stable enough to become the released version, but is being made available for customer evaluation of shipping readiness.
- Beta software is an early build release that is not quite ready for use in production environments, but is of sufficient quality to enable evaluation for feedback about the software.
- Previews enable us to provide more frequent releases to solicit early feedback that will help shape the software in its earliest stages.

The .NET Compiler Platform project (codename "Roslyn") includes the next versions of the C# and VB compilers, as well as a compiler-as-a-service API that powers rich IDE integration, and opens up the compiler to many different types of developer integrations. For more information, see .NET Compiler Platform Preview.
.NET Native is an ahead-of-time compiler for .NET that leverages our C++ compiler's optimizer to offer improvements to startup time, memory usage, and overall application performance. In this preview release, we enable developers to try out this new compilation technology for Windows Store application targeting x64 or ARM architectures. For more information, see .NET Native Developer Preview.
