Running Java, Python, Ruby and Perl programs in .NET
There's no practical common virtual machine or binary for the options you list. You will require a separate install for each of these (note that all are unrelated to .NET)
I've .NET framework 3.5 installed in my laptop. Just .NET alone, no Visual Studio. How can I run Java, Python, Ruby and Perl programs from the console? 
Do I need to install something else also, for running these language files?
In case there is a need for something extra to be installed and after i have all of them, what are the commands that I need to type in the console to run these programs?
