Could not load type 'umbraco.cms.businesslogic.datatype.DataEditorSettingValidationResult'

I'm trying to create a DataType which will use the usercontrolwrapper datatype in 4.7.0.

When I come to change the datatype's "Render control" option to "umbraco usercontrol wrapper" it throws the following error when I hit save.

TypeLoadException: Could not load type 'umbraco.cms.businesslogic.datatype.DataEditorSettingValidationResult' from assembly 'cms, Version=1.0.4089.21636, Culture=neutral, PublicKeyToken=null'.]
   umbraco.editorControls.userControlGrapper.usercontrolPrevalueEditor.Save() +0
   umbraco.cms.presentation.developer.editDatatype.save_click(Object sender, ImageClickEventArgs e) +38
   System.Web.UI.WebControls.ImageButton.OnClick(ImageClickEventArgs e) +187
   System.Web.UI.WebControls.ImageButton.RaisePostBackEvent(String eventArgument) +165
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +3707

I have reflected over the cms.dll and I can't see any DataEditorSettingValidationResult class.

Any ideas?

Please ignore this. I had originally installed 4.7.1 but Umbraco got confused and attempted to "upgrade" itself to 4.7.0 - which I admit I had just let it try and it didn't break anything so I had assumed everything was fine.

I have replaced the bin with the original 4.7.1 bin folder and this has fixed the issue.
