Subject: [xbuild] Add hooks for extending .sln builds.
X-Git-Url: http://wien.tomnetworks.com/gitweb/?p=mono.git;a=commitdiff_plain;h=9aba3ef7eb4949d46ee4f5f720a834e0e2e70e59

[xbuild] Add hooks for extending .sln builds.

Add hooks in the .sln.proj generated from .sln files.

1. It imports
   "$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\SolutionFile\ImportBefore\*"
   and
   "$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\SolutionFile\ImportAfter\*"
   This is done only in case of 4.0 projects, as imports with wildcard
   is a 4.0 feature.

2. And it imports before.Foo.sln.targets and after.Foo.sln.targets from
   the same dir as the .sln file.
