|
A simple python script to find out the .NET framework versions
|
||||||
|
installed on a local or remote machine. (remote machine does not work yet ;)
|
||||||
|
|
||||||
|
Usage:
|
||||||
|
donet.py [--machine|-m=<computer_name>] [--check|-c=all|1.0|1.1|2.0|3.0|3.5|4]
|
||||||
|
if invoked with a 32 bit python, 32 bit versions of .net framework will be returned;
|
||||||
|
if invoked with a 64 bit python, 64 bit versions of .net framework will be returned.
|
||||||
|
|
||||||
|
Sample Run:
|
||||||
|
C:\IronPythonPlay>'C:\Program Files (x86)\IronPython 2.7.1\ipy64.exe' dotnet.py
|
||||||
|
|
||||||
|
