The answer was given once, but since then the download site has changed (apparently). I can not find Castle.MicroKernel at all. 2.51 can no longer be downloaded, rather than 2.52. or 2.53.
No longer Castle.MicroKernel.dll, he was merged with Castle.Windsor.dll.
Castle.MicroKernel.dll
Castle.Windsor.dll
Namespaces anyway, i.e. the namespace Castle.MicroKerneland all its types now live inCastle.Windsor.dll
Castle.MicroKernel
