fix build break on mac
Merge pull request #81 from funnelweb/master

FSharp.Core.dll for net4+sl4+wp71+win8  (Fix #79)
Enable build of FSharp.Data.TypeProviders.dll

This enables the build of FSharp.Data.TypeProviders.dll via xbuild. The
WSDL functionality is disabled for nowdue to
ConfigurationChannelFactory not being defined on Mono.

None of the functionality is likely to work on Linux or Mac because the
command-line tools used by the type providers will not be found by the
registry searches used on Windows.
Undo setting of LKG which breaks build
Adjust assembly info
Remove warning
Added new target framework 'net40-xna40-xbox360'.
Ignore suo files.
