Release Notes

RC1 released 11/18/2015

Full details on this release can be read about in this blog post: Announcing .NET Core and ASP.NET 5 RC

Supported platforms for this release are Ubuntu 14.04 LTS, OS X 10.10, and Windows 7+.

Dependencies

.NET Core RC1 on Linux and OSX take dependencies on the following libraries:

  • libc, librt: I/O, process management, time, etc.
  • libunwind: call chain determination for exception handling and stack traces
  • gettext: resource strings
  • libicu: globalization
  • liblttng: runtime tracing
  • libuuid: guid generation
  • libcurl: HTTP
  • libssl & libcrypto: cryptography
  • libz: deflate and gzip
  • procfs & Core Foundation / Services: process and networking information on Linux and OSX

Compilation

  • Support csc compiler on .NET Core on Linux and OSX
  • Support vbc compiler on .NET Core on Linux and OSX

Runtime

  • GC/thread suspension for Linux and OSX
  • Integration of exception handling with debugger and crash dumps
  • Support for LLDB and SOS on Linux
  • RyuJIT ported to Linux and OSX, including JIT and crossgen
  • RyuJIT implements calling convention for structs passing on Linux and OSX
  • Runtime performance improvements
  • Native eventing support via LTTNG for Linux
  • Added 2800 Windows tests

BCL

  • More complete System.Globalization support on Linux and OSX
  • IDNA2008 support for internationalized domain names
  • X509 certificate support
  • System.Security.Cryptography.EcDSA class is supported on all platforms
  • CryptographicException contains both the numeric code (via the HResult property) and the message instead of the code only on Windows and the message only on Unix
  • System.IO 260 character (MAX_PATH) length limit removed on all OS (.NET Core only)

Network

  • System.Net.Http, System.Net.Primitives, System.Net.NameResolution, and System.Net.Sockets implement most features
  • System.Net.Sockets has new Task Parallel Library methods, and removed Begin/End pattern methods for consistency with other .NET Core APIs
  • System.Net.Http.WinHttpHandler updated to be fully asynchronous and scalable
  • System.Net.NetworkInformation available on all platforms
  • Basic support for System.Net.Security.SslStream: SslStream is enabled for Unix; AuthenticateAsServer works with an RSA certificate, and AuthenticateAsClient works without requiring a client authentication certificate
  • System.Net.Security.SslStream supports ECDSA certificates, and IP address SubjectAltNames are supported for host matching

Data

  • System.Data.SqlClient available on all platforms (MARS not yet supported)
