v0.4.6

Merge branch 'fixMultitargetingBuild'

Build everywhere

Fixed some issues with building across the various flavors of msbuild. Confirmed to work:

• dotnet build on Linux
• dotnet build on Windows
• msbuild from VS2017
• msbuild from VS2015

v0.3.4

Build all packages to the same directory

v0.3.1

Replace AdhocWorkspace with CSharpCompilation

This is a breaking change to our extensibility API, but it is necessary to completely eliminate the MEF cost that we incur for every project build. And should not adversely impact what code generators can achieve.

Fixes #18

v0.2.10

Merge pull request #15 from AArnott/netstandard

Add support for `dotnet build`
