Hi everybody,

I was working on a form created in code-first which was working perfectly, despite being modified constantly for the last couple of days. The DLL that contained the code-first form also contained FieldTypes, PreValue Source Types and PreValue Sources.

I decided to relocate the FieldTypes, PreValue Sources and PreValue Source Types to a separate project and keep the code-first form alone in it's own project. After replacing the DLL with the code-first form (plus other stuff) in the bin directory with the new DLL (the one with the code-first form by itself), I get a YSOD in the backend with the following error:

No provider with id '4085adac-0dba-11e4-8c8d-9c301e5d46b0' found

If I add the DLL to the bin directory of a test site, I can see that the form's GUID has changed. Why did it change if it's essentially the same form? Is there a way I can set the form's GUID to its previous value?

I need to remove the YSOD because its happening in a production site. Is it possible to do so without having to re-install Contour?

Thank you for your help.
