v1.12.0-beta2

Editor

• Go to Definition now works from "metadata as source" files (#771, PR: #1620) (Contributed by @filipw)
• Selection-based code fixes and refactorings (such as "Extract Method") will no longer be offerred unless there is actually a selection in the editor. (#1605, PR: #1606)

Project System

• Use MSBuild solution parsing API, which is the official parser for handling weird solution file cases. (1580, PR: omnisharp-roslyn#897)
• The MSBuild project system now calls the "Compile" target rather than the "ResolveReferences" target when processing MSBuild files. This has the effect of ensuring that other targets have the opportunity to run (such as targets that generate files) while still not building any output binaries. (#1531)
• Binding redirects added for MSBuild assemblies, fixing issues with MSBuild tasks built with different versions of MSBuild. (omnisharp-roslyn#903)
• The OmniSharp serverhas updated to the latest MSBuild. (omnisharp-roslyn#904, PR: omnisharp-roslyn#907)

Scripting

• Support added for referencing NuGet packages in C# scripts. (PR: omnisharp-roslyn#813) (Contributed by @seesharper)
• System.dll is now added correctly for C# scripts targeting .NET Framework. (omnisharp-vscode#1581, PR: #898) (Contributed by @filipw)

Other Updates and Fixes

• All project systems (project.json, MSBuild, CSX Scripting) now support an "Enabled" property that can be configured in omnisharp.json. (PR: omnisharp-roslyn#902) (Contributed by @filipw)
• The OmniSharp server has been updated to Roslyn 2.3.0-beta2, which adds support for C# 7.1 (PRs: omnisharp-roslyn#900 and omnisharp-roslyn#901)
