Is there a way to determine the .NET Framework version from the command line?

Question

To troubleshoot an installation, sometimes I just want a quick answer to what version of .NET is installed.

Is there a way to determine the .NET Framework version on

Answer 1

The following would detect if .net framework 3.5 is installed or not.. and if not installed will install it. Just run this on the command prompt.

if exist "%WINDIR%\Microsoft.Net\Framework\v3.5" goto end start /wait .\Framework\dotnetfx.exe /q /norestart" :end 

If you want to detect other versions just replace v3.5 with v2.0 or v1.0 as the case may be. Further if .net is not detected the installation of the .net framework would be done in silent mode i.e. no ui or user interaction.
