You define extension methods in your hosting app, right? We're still working
out the details of our second attempt to fix this problem. In the short term,
the workaround is to define your own private copy of ExtensionAttribute in any
hosting project that defines extension methods. That requires the following 4
lines of code:
namespace System.Runtime.CompilerServices {
[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class |
AttributeTargets.Assembly)]
sealed class ExtensionAttribute : Attribute { }
}

Subject: [Ironruby-core] Usage errors with IR SVN 153
Reverting back to IR SVN 153, I was getting it compiled.
However, when switching to use the the SVN 153 compiled binaries
(upgrading from SVN 141) in my IronRuby-embedding app, I get following
compilation errors:
------ Build started: Project: gui, Configuration: Debug Any CPU ------
