Displaying .NET Framework Versions

In supporting or diagnosing .NET based products, I often find it useful to check what versions of the .NET Framework are installed on a given machine. Most programmers know by now how to do this by checking the registry or some file on disk. But when you’re on the phone to a customer you want a simple solution that does not involve them cranking open the registry. What you need is a simple, low-tech solution.

1. Open the Run dialog box by typing Win+R.

2. Type the following command:

cmd /k dir %windir%\microsoft.net\framework\v?.* /b

Admittedly this could also be error prone to communicate over the phone. I suggest you send the customer an email.

:)

On my machine, it results in the following displayed in a console window:

v1.0.3705
v1.1.4322
v2.0.40426
v2.0.40510
