To install .NET Framework 3.5 for Windows 10, do the following:
- Look for your deploymentshare on your MDT/WDS server. In my case it is : “E:\DeploymentShare\Operating Systems\Windows10Prox64-1611\sources\sxs” check the quotes because of the spaces
- Now open an elevated command prompt and type the following command:
Dism /online /enable-feature /featurename:NetFX3 /All /Source:"E:\DeploymentShare\Operating Systems\Windows10Prox64-1611\sources\sxs" /LimitAccess
Replace E: with your drive letter
You are done! This will install .NET framework 3.5 for Windows 10 deployment.
