mvvm-light

问题 I'm trying to use Entity Framework Core with UWP. I found this sample from Microsoft and got it to work. In this sample, the object models are in a .Net Standard class library.

The issue I'm running into is that MVVM Light is apparently not compatible with .NET Standard 2.0, only 1.0. MVVM Light does seem to install correctly to the class library, but

问题 I am using MVVM Light libraries only (from Nuget package) in my Windows Phone 8 project and I want to use EventToCommand in ToggleSwitch .

问题 I am reading this http://msdn.microsoft.com/en-us/magazine/jj651572.aspx to learn mvvm light framework. I download the source code Friend.cs. My question is why some set method of different property are implemented differently. For example, the setter for First name is, why I need 'ref' keyword for _firstName. Set(FirstNamePropertyName, ref _firstName, value); And the setter for DateOfBirthString is " RaisePropertyChanged(() => DateOfBirth); When will the linq expression will be evaluated?
