[Mono-list] Parallel.ForEach & MaxDegreeOfParallelism

[Daniel Lo Nigro]

This number is also publicly documented though, you don't need to decompile
the code to find it. :P

http://msdn.microsoft.com/en-us/library/system.threading.tasks.taskscheduler.maximumconcurrencylevel.aspx
Returns an integer that represents the maximum concurrency level. *The
default scheduler returns Int32.MaxValue.*

To get the same behaviour as the .NET runtime, you may be able to create
your own class that extends TaskScheduler and override the
MaximumConcurrencyLevel property.
