🐛 Bug Report

Error CS0263 Partial declarations of 'SomeView' must not specify different base classes

Expected behavior

the nullable attribute shouldn't affect the MvxWpfView

Reproduction steps

create a mvvmcross wpf project and add the nullable attribut in project settings

<Project  Sdk="Microsoft.NET.Sdk.WindowsDesktop>
 ....
<PropertyGroup>  
<Nullable>enable</Nullable>  
</PropertyGroup>  
<Project>  

create a view:

<views:MvxWpfView  
x:Class="BlaBla.SomeView"  
xmlns:views="clr-namespace:MvvmCross.Platforms.Wpf.Views;assembly=MvvmCross.Platforms.Wpf"  
x:TypeArguments="SomeViewModel">  
<Grid>  
...  
</Grid>  
</views:MvxWpfView>  

with a basic code behind:

 public partial class SomeView : MvxWpfView<SomeViewModel>
    {
        public SomeView ()
        {
            InitializeComponent();
        }
    }

You don't have to specify the base class in all partial class definitions (one is enough). Hence the error will go away if if you remove : MvxWpfView<SomeViewModel> from the .cs file but the class will properly inherit from MvxWpfView<SomeViewModel> since the base class is define in the XAML.
