{
if (!compilation.ContainsSyntaxTree(tree))
{
var newTree = tree;
if (!tree.HasCompilationUnitRoot)

SyntaxFactory.List(childNodes.OfType<UsingDirectiveSyntax>()))
.WithExterns(
SyntaxFactory.List(childNodes.OfType<ExternAliasDirectiveSyntax>())));
}
var comp = compilation.AddSyntaxTrees(newTree);
return new Tuple<Compilation, SyntaxTree>(comp, newTree);

ImmutableDictionary<DocumentId, SyntaxTree> oldMap, ImmutableDictionary<DocumentId, SyntaxTree> map,
CancellationToken cancellationToken)
{
foreach (var oldIdAndTree in oldMap)
