AutoCAD auto exited after calling SaveAs method for a nodocument database

I'm writing a service that creates and returns a dwg file to end user.
What I expected is that an AutoCAD instance working on the same computer of the service and listen to a specified command. Whenever receives the command, the command handler will create a new database with buildDefaultDrwaing(true) and noDocument(true), append some entities to modelspace, then save this database to computer's temp folder.
However, the AutoCAD instance exits after the SaveAs method called every time.
Here is the code:

[CommandMethod("testcode", CommandFlags.Modal)] public void TestCode() { try { using (var database = new Database(true, true)) { HostApplicationServices.WorkingDatabase = database; using (var acTrans = database.TransactionManager.StartTransaction()) { var modelSpace = acTrans.GetObject(SymbolUtilityServices.GetBlockModelSpaceId(database), OpenMode.ForWrite) as BlockTableRecord; var dim = new AlignedDimension(new Point3d(0, 0, 0), new Point3d(10, 0, 0), new Point3d(10, 0, 0), "", ObjectId.Null); modelSpace.AppendEntity(dim); acTrans.AddNewlyCreatedDBObject(dim, true); acTrans.Commit(); } // var path = Path.GetTempFileName().Replace(".tmp", ".dwg"); database.SaveAs(path, DwgVersion.AC1027); } } catch (Exception e) { Console.WriteLine(e); throw; } catch (System.Exception e) { Console.WriteLine(e.Message); } }

You have to restore previous value of HostApplicationServices.WorkingDatabase
