The page seems to have disappeared in the currently archived version of Jason Zander's blog at https://learn.microsoft.com/en-us/archive/blogs/jasonz/ - so replace it with a Wayback Machine link to an archived version.

+| SOS | [Son of Strike](https://learn.microsoft.com/dotnet/framework/tools/sos-dll-sos-debugging-extension). The debugging extension for DbgEng based debuggers. Uses the DAC as an abstraction layer for its operation. The obscure name derives from the original nickname for the CLR team at Microsoft: "Lightning". The team built a debugging tool humorously named "Strike", and a subset of that dubbed "Son of Strike". |

 | SVR | The CLR used to be built as two variants, with one called "mscorsvr.dll", to mean the "server" version. In particular, it contained the server GC implementation, which was intended for multi-threaded apps capable of taking advantage of multiple processors. In the .NET Framework 2 release, the two variants were merged into "mscorwks.dll". The WKS version was the default, however the SVR version remained available. |
