    “What does "-StartupCmd=KernelComileAll" do in "kernel compilation"?

    Unlike what may be interpreted from some documentation pages (“Perform a full kernel compilation by using the following command: Ax32.exe -startupcmd=kernelcompileall”), this command does not compile the kernel; it does a full AOT compilation, i.e. it compiles the application. However, instead of using X++ classes to control that compilation and log the results, this operation is done by a kernel function. During minor version upgrade, majority of the class required to be recompiled, including many system class/compiler related class. The kernel compile is required for minor version upgrade as it force a full compile on every class in AOT, including those system/compiler class, and are executed on server tier. Without running the kernel compiler ax won’t even function properly as the base application class are not even compiled to begin with.”
