What is the maximum size that maxReceivedMessageSize can be set to for a NetNamedPipeBinding?

Question

I noticed that 2147483647 seems to be a popular choice for maxReceivedMessageSize but is this the limit?

On the other hand, you might want to consider that setting it to 2 GB of message size means your WCF server will potentially have to deal with several messages of up to 2 GB in size simultaneously - can it do that?? Marc — marc_s, Jun 17 '09 at 04:49

Nope, the limit is Int64.MaxValue¹ which is: 9223372036854775807

In the web.config-File, only the Int32-limit seems to work. Maybe it's a parsing issue. – marsze Sep 17 '15 at 11:52

When setting this value through code I get `ArgumentOutOfRange` exception for this parameter. – BartoszKP Nov 01 '16 at 23:29

MaxMessageReceivedSize in basicHttpBinding appears to be an int32 - setting it over the max value of an int32 results in:

This factory buffers messages, so the message sizes must be in the range of an integer value. Parameter name: bindingElement.MaxReceivedMessageSize

Nope, it's Int64 (long): http://msdn.microsoft.com/en-us/library/system.servicemodel.basichttpbinding.maxreceivedmessagesize%28v=vs.100%29.ASPX – Darren Griffith Jun 11 '14 at 17:45

MaxReceivedMessageSize and MaxBufferSize must same value and MaxBufferSize is Int32.

Not true - MaxBufferSize is only used if you are using Buffering. If you are using Streaming, then it is ignored. This is why MaxReceivedMessageSize is Int64 and can be different to MaxBufferSize. – Robert MacLean Feb 26 '13 at 10:44
Do you mean maxBufferPoolSize and maxReceivedMessageSize? – Gary Dec 10 '13 at 19:55
BasicHttpBinding MaxBufferSize is Int32, but MaxReceivedMessageSize is Int64. http://msdn.microsoft.com/en-us/library/system.servicemodel.basichttpbinding.maxbuffersize%28v=vs.100%29.aspx – Darren Griffith Jun 11 '14 at 17:47
