Windowscommunitytoolkit: ViewportBehavior sample is empty

[yoshiask]

Describe the bug

The sample page for ViewportBehavior is broken because the type ViewportBehavior could not be found.

This is the first time I've noticed the issue, though it's probably not a regression.

Steps to Reproduce

1. Go to the ViewportBehavior sample page
2. Sample area is empty, look at the XAML
3. See error on line 17, position 53

Expected behavior

The sample should be available and functional

Thanks @yoshiask!

This is due to .NET Native optimizing out the type for release mode and how we dynamically load the XAML in the samples for our cool sample app experience.

Basically, a 'dummy' version of whatever type is being used needs to be copied into the Sample Page's XAML here as we call out in our Sample App docs here. Looks like this step was forgotten on this sample when it was added originally.

Is this something you'd be interested in helping fix?

[yoshiask]

@michael-hawker Yeah, I'd love to help fix this! I'll take a look at those docs.

@yoshiask if you haven't built the toolkit yet, I'll have a video going up in the morning explaining how to do that. :)

@yoshiask any update regarding the doc?

[yoshiask]

@Kyaa-dost Sorry, I've been very busy this last week. I just cloned and got the Toolkit building tonight, so tomorrow morning I'll finally finish this.

[michael-hawker]

@yoshiask were you still planning to submit a fix? We'd need it in the next day or so. Otherwise, we can handle it. Just want to know. Thanks!

[yoshiask]

@michael-hawker I've been trying to get the Tookit to build for the last week and it still won't work, I think there's something weird with my VS install. I'll pass this back to you guys. Sorry for the trouble!
