.Net Framework 4.0 Compatiblity with Windows Server 2012

Question

I have an application that requires the .NET Framework 4.0. The application supports running on Windows 8 and Windows Server 2012, which both include the .NET Framework 4.5 as a part of the operating system.

Does my application installer still need to install the .NET Framework 4 on these operating systems even though the .NET Framework 4.5 is already installed?

Answer 1

.Net Framework 4.5 replaces 4.0; it is backward compatible so no, you don't need to install 4.0.
