是否有可能编译.NET IL code到机code？

是的，你可以使用Ngen.exe，但是这不会删除CLR依赖precompile。

Yes, you can precompile using Ngen.exe, however this does not remove the CLR dependence.

您还必须运送IL组件为好，NGEN的唯一好处是，你的应用程序可以启动，而不必调用JIT，所以你得到一个真正的快速启动时间。

You must still ship the IL assemblies as well, the only benefit of Ngen is that your application can start without invoking the JIT, so you get a real fast startup time.

据CLR通过C＃：

此外，使用组件precompiled   NGEN通常比JIT'ed慢   组件因为JIT编译器   可以优化到目标机器   （32位？64位？特殊寄存器？   等），而NGEN只会产生   基准编制。

Also, assemblies precompiled using Ngen are usually slower than JIT'ed assemblies because the JIT compiler can optimize to the targets machine (32-bit? 64-bit? Special registers? etc), while NGEN will just produce a baseline compilation.

编辑：

有来自CLR通过C＃上面的信息存在争议，因为有些人说，你必须只作为安装过程的一部分，在目标机器上运行NGEN。

There is some debate on the above info from CLR Via C#, as some say that you are required to run Ngen on the target machine only as part of the install process.
