Msbuild support for Dlr language inline tasks.

Sample MSBuild file:

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0"
     DefaultTargets="Build"
     xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <UsingTask
    TaskName="HelloWorld"
    TaskFactory="DlrTaskFactory"
    AssemblyFile="$(TaskFactoryPath)DlrTaskFactory.dll">
    <ParameterGroup>
      <Name Required="true"/>
      <TaskMessage Output="true"/>
    </ParameterGroup>
    <Task>
      <Code Type="Fragment"
            Language="rb">
        <![CDATA[
        self.task_message = "Hello #{name} from Ruby".to_clr_string
        log.log_message(task_message);
        ]]>
      </Code>
    </Task>
  </UsingTask>
  <PropertyGroup>
    <YourName Condition=" '$(YourName)'=='' ">Jim</YourName>
  </PropertyGroup>

  <Target Name="Build">
    <HelloWorld Name="$(YourName)">
      <Output PropertyName="RubyOut"
              TaskParameter="TaskMessage"/>
    </HelloWorld>
    <Message Text="Message from task: $(RubyOut)"
             Importance="high" />
  </Target>
</Project>

And it's output:
