Run time error - EPiServer.fields.basesample.dll not found.
Vote:
Hi,
One of my EPiServer applications was running perfectly and suddenly it started throwing a run time error as below.
Following is the error details (Stack Trace):
--------------------------------------------------------------------------------------------------------
Message: File or assembly name EPiServer.Fields.BaseSample, or one of its dependencies, was not found.

---- 1) If we see the above stack trace some DLL is being loaded at runtime.
---- 2)If I change my web.config (EPsConnection)to point to a different database (located at User Acceptance Test), the application runs fine.
---- 3) When the application was running fine, it didn't have any reference to the DLL - EPiServer.fields.BaseSample.
----- I tried to add this DLL when the error occured but this didn't help.
Kindly help me to understand the reason and possible solution for the same.
Thanks in advance.

Hi,
you have a custom property type that is registered, but the assembly it has been registered in does not exist any longer.
Open Admin (it should still work). Under the Page Type tab, select Edit Custom Property Types. You should see one or more properties there that reference an assembly or class that you no longer have in your application. Delete these, when you get to one or more that is in use, you will get an error telling which page types it is used on. Fix this, and then delete it. The site should then work ok.
This typically happens if you rename an assembly, and it has one or more custom property types set to auto register.
Also note that the Class name and Assembly name headings in the list is switched. It should be the other way around.
