C# 8.0 and Project-wide nullable reference types

C# 8.0 is available for use in Visual Studio 2019 Preview.  Mads Torgersen explains some of the key features in this video.

He explains how to enforce usage in a single file using

#nullable enable

What Mads doesn't explain is how to fully accept the new Nullable Reference Types for your entire project.

The secret is to add this to your .csproj file:

<NullableReferenceTypes>true</NullableReferenceTypes>

It goes here:

Now your whole project enforces nullable reference types!

Skype video 180 degree flip bug

Now this is the story all about how
MY VIDEO GETS FLIPPED, TURNED UPSIDE DOWN
And I'd like you to take a minute just sit right there
I'll tell you how it seems like I hang in mid air

On a three-screen setup, born and raised
On the middle screen is where I rest most of my gaze
Coding stuff, mailing, relaxing all cool
And all Skyping some colleagues, pairing .NET rules
When a touchscreen grabs my eye, now this looks good!
Order it on Amazon? Of course I should!
Flat on desk *under the main screen* but the cables go where?
I said "Display settings | Orientation | 'Landscape flipped'.  So there."

I called my mate on Skype and the video was here, the
Highest bitrate fresh and the audio was clear
If anything I could say all elements were there
But I thought "oh, FFS, I'm up in the air!"

I thought about trying Windows seven or eight
And I tried Zoom and WebEx - "Right way up! Skype you later!"
Clicked Skype | Help | Feedback - I was finally there
To log this bug down - hope you think that that's fair.
