3.0 Preview 1

This is a preview release! Framework requirements: .NET 4.6.1 or higher.

Language support status can be found in issue #829, please note that this is a live issue and might have changed after this preview has been published. Notable missing feature compared to older versions: nullables. (only fully implemented features have a checkmark in the status issue). Before opening an issue ("X doesn't decompile correctly") please go check with issue #829!

New: support for .NET Standard and .NET Core assemblies.

Missing: decompile to VB. Contributions welcome because we concentrate solely on C#.

Architectural changes are documented in the wiki (Note: roadmap not up to date as of this release). Important points to note (design goals): the decompiler should always create semantically correct and compilable code.
