Finally, the missing piece from the entire Net Yaroze collection. In previous posts we've seen the US/UK kits, the Japanese kit and the Lightwave 3D. Also, the Metrowerks Codewarrior for Net Yaroze 1.7 was leaked many years ago and can be easily found in the interwebs.
Here is the latest version of Metrowerks CodeWarrior for Net Yaroze that was released back in the day.
Metrowerks CodeWarrior for Net Yaroze R2 - for PC and Mac
This is an Integrated Development Environment (IDE) to program using the Net Yaroze. It helps simplifying project management (at a development level) and provides a more powerful and convenient way of programming.
It includes its own debugger, compiler and documentation, though you still need the Net Yaroze SDK to use this (since it contains the libraries required).
A patch (update) was released for this version in the Net Yaroze members website (and probably in Metrowerk's website as well), which you can find below (obtained from the member's website archive uploaded in this forum by unclejun).
As much as I'd like to copy-paste the release notes here, it's too much text; however these are included in the ISO.

Here's a description/overview directly taken from the documentation (dated September 23, 1997):
The CodeWarrior IDE (Integrated Development Environment) is the
center of CodeWarrior software development. This powerful IDE
combines a sophisticated project manager, source code editor,
browser, compilers, and linkers that you use to develop PlayStation
software from your choice of a Windows 95/NT or Mac OS computer. The
same IDE also supports development for a variety of other processors
and operating systems using plugin compilers and linkers (available
in other CodeWarrior products).
Metrowerks C/C++ Compiler for MIPS(TM)
The Metrowerks C/C++ compiler for MIPS combines the industry-proven
Metrowerks C/C++ front-end with a MIPS backend. The compiler's front
end is fully ANSI/ISO C compliant and tracks the emerging ANSI/ISO
C++ standard. The back end supports the MIPS ABI and generates object
code for a variety of MIPS processors.
We've made several enhancements to the compiler to ensure that you
can make the most of your time and code:
* Declaration specifiers allow you to specify in which data section
in the object code to store variables and objects.
* The compiler supports both function-level and inline MIPS assembly
within a C/C++ source code file.
