I've got this far:
var curDataType = _dataTypeService.GetDataType("SteveTest");
var curConfiguration = (Umbraco.Cms.Core.PropertyEditors.MediaPicker3Configuration)(curDataType.Configuration);
curConfiguration.StartNodeId = Udi.Create(Constants.UdiEntityType.Media, Guid.Parse("cf7caaed6477472f9ef157f808f9a15e"));
curDataType.Configuration = curConfiguration;
This gives me:
System.ArgumentException: 'Configurations are kinda non-mutable. Do not reassign the same object. (Parameter 'value')'

10/03/2023, 2:50 PMDave Woestenborghs has solved it for me (via the forum):
var curDataType = _dataTypeService.GetDataType("SteveTest");
((Umbraco.Cms.Core.PropertyEditors.MediaPicker3Configuration)curDataType.Configuration).StartNodeId = Udi.Create(Constants.UdiEntityType.Media, Guid.Parse("cf7caaed6477472f9ef157f808f9a15e"));

Saves

10/04/2023, 7:24 AMYes- the issue is I was setting the entire configuration back - DW's way just operates on it rather than cloning it and reassinging the whole configuration.
You're right - the next line is obviously a _contentService.Save(xx)
I've seen a forum post asking for exactly the solution I was trying to build here - I'll post the full code if I find it as no doubt it will be me googling the same thing in 6 months 🙂
