WPF Developer - Save UI objects to Xml file, update context UI from Xml (Deseriallization/Serialization)

Small MVVM project; I need a C#/WPF developer to do the next task: Run the project click one button will display a form: - (after drag and drop any object to the main form) the object coordinates and size most pe saved in a Xml file (Xml object seriallization); when modify the position and the size of any objects the xml file most be updated according with the new coordinates and new size (for the specific object); - after close the project window and reopen the objects position and size most be according with the last modifications for each different button (Xml object deseriallization); I need all source code for this work - create a zip file and send the source code to chat - I will check ASAP. If the project working I will release the money and I will give you a new task. - Please use: "WPF UI objects Serialization" the title to show you have read this. - I attach the debug file (exe file) so you can check how much time you need for all this; - If we agree with the time and money I will send you the source code so you can start work. Thank you, ------------------------------------------- Looking forward to your bid.
