I upgraded the provider from 2.7.0.0 to 2.7.5.0. When running some LINQ it
is working fine in older version, whereas it is throwing in newer version as
follows
An exception of type 'System.ArgumentNullException' occurred in mscorlib.dll
but was not handled in user code
Additional information: Value cannot be null.
Not just one query in most of the queries !!!
Here is the stack trace
System.ArgumentNullException was unhandled by user code
Message=Value cannot be null.
Parameter name: key
ParamName=key
Source=mscorlib
StackTrace:
at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue
value, Boolean add)
at System.Collections.Generic.Dictionary`2.set_Item(TKey key, TValue
value)
