/// An internal redefinition of ICompilerOptionsHostObject from Microsoft.CodeAnalysis.BuildTasks. We cannot take
/// a binary dependency on the build task because no component in Visual Studio may do so -- we cannot rely that any
/// specific version of the build task is present since the customer may have a NuGet package installed that contains
/// different versions. Since this a COM interface, it's easiest to redefine.
