Create a new folder using FilesRoutes.BeginCreateFolder method

Yes, there are a few ways to do this. Here are three different versions I put together:

             // blocking
             Dropbox.Api.Files.FolderMetadata folderMetadata = await client.Files.CreateFolderAsync("/new_folder_via_CreateFolderAsync");
             Console.WriteLine(folderMetadata.PathLower);
 

         static void CompleteCreateFolder(IAsyncResult result)
         {
             Console.WriteLine("CreateFolder completed.");
             Dropbox.Api.Files.FolderMetadata folderMetadata = client.Files.EndCreateFolder(result);
             Console.WriteLine(folderMetadata.PathLower);
 
         }
...
             // non-blocking
             IAsyncResult result = client.Files.BeginCreateFolder("/new_folder_via_BeginCreateFolder", new AsyncCallback(CompleteCreateFolder));

             // blocking
             Dropbox.Api.Files.FolderMetadata folderMetadata = client.Files.EndCreateFolder(client.Files.BeginCreateFolder ("/new_folder_via_BeginCreateFolder"));
             Console.WriteLine(folderMetadata.PathLower);
