The ECMA standard for the .NET Common Intermediate Language has been updated three times. I haven’t been able to find a version history that would make clear the changes between the versions. Are there any substantial differences between the four, e.g. new opcodes etc.?
Also: Is the same true for MSIL?
Thank you!
Yes, the first two editions didn’t have generics – that’s by far the biggest change.
The third edition has a list of major changes in the foreword.
I don’t know about the differences between 1/2 and 3/4… I suspect those were very minor changes.
(I also don’t know whether the ECMA C# spec will ever catch up with the Microsoft version… the current ECMA version is C# 2.0 basically.)
