NuGet Warning NU5106

The file at 'lib\WinRT\temp.dll' uses the obsolete 'WinRT' as the framework folder. Replace 'WinRT' or 'WinRT45' with 'NetCore45'.

Issue

A file was detected to be under an WinRT or WinRT45 target framework folder under the lib folder. However, WinRT and WinRT45 target frameworks are now obsolete.

Solution

Please rename the target framework folder to NetCore45.
