We have released Portable PowerShell for V3 Beta. We have only gotten the 32bit version working so there is no 64 Bit, and also no ISE. We won’t be looking further into the issues we had with both until there is a next version of V3 whether its another CTP\Beta\Release Candidate or RTM. Also not all features may work. For instance I know that workflow doesn’t work. Many things do but we haven’t done a full feature comparison.
an important thing is if there are issues, don’t presume it’s a PowerShell V3 Bug, as it could be related to Portable PowerShell. Please do not submit bugs to Microsoft until you’ve validated them on real PowerShell.
You can go to www.portablepowershell.com and download it from there and also download the original Portable PowerShell that covers V1 and V2 both 32 and 64 bit, and also ISE.
