I've been having fun with the latest drop of PoSh. I'll be showing a demo of how to manage workitems on Team Foundation Server with a PoSh script at Saturday's CodeCamp.
One annoyance with the current RC is that it is slow to start. I saw a thread on the newsgroup about performance and found this nugget:
set-alias ngen C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\ngen.exels $pshome/*.dll |%{ngen install $_.fullname }
The ngen utility compiles .NET assemblies to native code. Without this step, the PoSh process was performing a JIT compile on all the PoSh assemblies. Apparently, this is supposed to happen at the end of installation, but doesn't as a result of a bug. For now, this makes my play... er, work with PoSh even more fun.
