Trying to update Microsoft.Build.Framework using Nuget in my SLN and getting the below error. This is VS 2017 Enterprise Version 15.9.1
Projects all target NET461 in this sln.

I duplicated this problem on 2 different windows 10 machines with the same project.

What can I do to get these packages updated?

Output

'System.Xaml' which was not found in the GAC

Your project is probably target .Net 3.5, which does not have this DLL. You can update the framework version in Project Properties.

If above not resolve your issue or you do not want to change your framework version, you can manually add the reference System.Xaml to your project:

Go to References -> Add Reference... and then click on Browse..

Add the file, which is located on (Windows 10): C:WindowsMicrosoft.NETassemblyGAC_MSILSystem.Xamlv4.0_4.0.0.0__b77a5c561934e089System.Xaml.dll

Then update your nuget package.

Hope this helps.
