How can I install .Net 3.5 on Windows 10?

Question

I need to install .Net 3.5 so I can use SQL Server Express/Local Db in Visual Studio.

I have trawled the internet looking for answers and nothing works.

It got stuck on this all night, this is enabling .Net 3.5 from the Control Panel.

I even redownloaded Windows 10 and run this DISM command

DISM  /Online  /Enable-Feature  /FeatureName:NetFx3  /All  /LimitAccess  /Source:c:\sources\sxs

but it still hangs and won't do anything.

If anyone could help me out that would be super helpful

.NET 3.5 cant be install by internet. you have to use your installation DVD or ISO downloaded from Microsoft website. use this command to install

DISM /Online /Enable-Feature /FeatureName:NetFx3 /Source:d:\sources\sxs /All /LimitAccess

d: should be the

• ISO mapped drive if you use ISO file
• DVD drive if you use installation DVD

Few important points.

• If you use ISO file, There can be errors if you try to use a ISO from a network location.
• If you download ISO from Microsoft web site careful about 32 bit and 64 bit.
• Run command prompt as Administrator to run this command
• If your command prompt hang without any response, probably it means Some windows updates installation is in progress. So restart the computer and try again.
• Go to "Turn Windows feature on or off" window.If you installed properly, you can see .NET framework 3.5 is installed.
