Where can I find the definitions of System.Collections.Concurrent classes in the mono source code?

Question

I am looking for the source code of the System.Collections.Concurrent classes, especially ConcurrentQueue and ConcurrentDictionary in the mono sources. I am unable to find them.

I was looking in the corlib Directory:

https://github.com/mono/mono/tree/master/mcs/class/corlib

but it does not contain the System.Collections.Concurrent package. Even using the repository search feature of github did not yield the source code.

There was already a question which asked a similar thing, but the links provided in the answer are dead. So where are the collection sources in the repository?

Answer 1

Mono from version 4.0 started to include source code that Microsoft opened sourced as reference source .

The last version of Mono that included its own version of the concurrent classes code was Mono 3.12 and that has the ConcurrentQueue and ConcurrentDictionary classes .

For later versions of Mono the source code for the System.Collections.Concurrent namespace is in the mono/referencesource GitHub repository, which is a fork of Microsoft's reference source repository .
