Exception filter syntax with 'when' should be consistent to C#8 pattern matching syntax

[PhilippPaetzold]

                try
                {
                ... 
                }
                catch (SocketException ex) when (ex.SocketErrorCode == SocketError.TimedOut)
                {
                ...
                }

would be nicer and more consistent, with c# 8 pattern matching syntax:

                try
                {
                ... 
                }
                catch (SocketException ex when ex.SocketErrorCode == SocketError.TimedOut)
                {
                ...
                }

Is there a technical reason for the different syntax or is it simply because exception filtering with the 'when' keyword came first with C# 6.0?

Yes.
