Just walked through referencesource.microsoft.com (line 217)
and discovered "|=" operator. What does it means? I assume it some sort of Boolean operation- but can't get what exactly it means. Does it mean "or equal", short form like "a= a|b" ?

2Do you know about `+=`? As in `a += b`. Same thing. – Thilo May 06 '15 at 10:16

2You can check that by reading the [documentation](https://msdn.microsoft.com/en-us/library/h5f1zzaw.aspx) – Panagiotis Kanavos May 06 '15 at 10:16

|= is to = what += is to =. Just a shortcut to avoid the writing of a = a | b

its a bitwise inclusive OR and assignment operator.

You are correct. This operator is known as the "OR assignment" operator and a |= b is equivalent to a = a | b. Here is the documentation.
