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?

Answer 1

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

Answer 2

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

Answer 3

MaxReceivedMessageSize and MaxBufferSize must same value and MaxBufferSize is Int32.

Answer 4

Use the defaults for the maximum size so one doesn't fat finger a value:

binding.MaxBufferSize          = int.MaxValue;
binding.MaxReceivedMessageSize = long.MaxValue;
