Just a quick one to bring your attention to something what you may have missed.
Microsoft released a command-line tool for Dynamics AX R2 CU 7 called AxBuild. It’s capable of compiling X++ code directly on AOS and doing it in several threads in the same some time, which has a huge effect on performance. Microsoft even achieved 92% (!) improvement in compilation time (in a carefully built environment).
One more advantage is that it’ll be easier to get response from a running compilation (that’s a trouble particularly with compilations executed by automated scripts). Unfortunately AxBuild doesn’t cover compilation to CIL, but hopefully we’ll get that too, at some point.
I haven’t had a chance yet to play with it, but Tommy Skaue did, so check out his blog post You got to love AXBuild Compiler Tool.
