The above post about "Blocking Issues" when running the setup.exe from the extracted files is respectfully, incorrect. You must add an extra switch, either "/x86" or "/x64" in addition to the options you select.
With a simple dotNetFx40_Full_x86_x64.exe /q /norestart it installs silently. The help dialog does not prompt :)
Doing some lab testing for ConfigMgr 2012. I wanted to install App-V 5.0 Beta but it needed the .NET Framework 4 Full as a prereq. So, created the .NET Framework 4 Full application with the following command line:
dotNetFx40_Full_x86_x64.exe /q /norestart /ChainingPackage "SCCM 2012"

You can deploy .NET 3.5 on Windows 8 machines by calling DISM in two ways an online option
DISM /Online /Enable-Feature /FeatureName:NetFx3 /All
OR a source media option
DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:d:\sources\sxs
dotNetFx40_Full_x86_x64.exe /q /norestart /ChainingPackage ADMINDEPLOYMENT
