I am using Provider 3.0.2.0 with EF 5.0 code First. When I call save changes
it is giving FirebirdSql.Data.Common.IscException: attempted update of
read-only column. I have trigger for id column and I don't include values
for those columns in code and there is no other computed column. I also
tried saving a different table, but no use, when savechanges is called it is
throwing the exception.
Here is the exception stack details.
