'WindowsBase', 'PresentationCore', 'PresentationFramework' are missing from the target framework

Question

I am trying to load a solution in Visual Studio 2013 but I am receiving this message:

When I click OK it shows another error message:

Attempted re-targeting of the project has been canceled. Required assemblies 'WindowsBase', 'PresentationCore', 'PresentationFramework' are missing from the target framework.

I have all .NET Framework installed (I am running Windows 10) and I already tried the .NET Framework Repair Tool (https://support.microsoft.com/en-us/kb/2698555).

Answer 1

Open that project file in notepad and change .net version to < your project .net version > and try loading it in VS 2013
