You can also use https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/DatagramSocket to demonstrate this issue. Use scenario 5 to listen for multicast traffic and observe nothing is received until after hitting the send button.

It would be nice to use rating control with partial stars.

It can be a Step property.
For example: Step = 0.5 and MaxValue = 5.

Thanks!

Today we have the x:DefaultBindMode attribute to define the default binding mode generated for a compiled data binding created with x:Bind.

We can set that mode on an element or on a parent element.

It would be a huge advantage to support this attribute also on the App-object in the App.xaml-file, and to make this the "ultimate root".

This would allow me to specify an application wide default binding mode, and I could set it in this single place for example to OneWay.

I have used Unity+UWP to develop LOB application that visualizes 3D data from opened files. We also use multiple-top-level windows that are already available. Now client wants to allow opening and visualizing multiple files, which would have been easy with Win32 (just launch another instance). One of the problems in here is Unity code, which is mostly made to be single-instance, but it would be great to have support to launch multiple instances of the same app.

It's a pain to use the TimePicker control on desktop. When selecting the minutes, you have to scroll through a huge list of 60 numbers...

Instead, you should be able to just type "45" to select 45!

I'm using the time picker in my app, Power Planner, and two users have complained about this (and I've complained about it myself). This should be part of the built-in control! It's quite terrible to use on desktop presently!

Notepad has been updated to support Line endings from Unix, Linux, and Mac. I think we should take it one step further and make Notepad opensource like Powershell so the open-source community can continue to add features to Notepad to become the go-to text editor for performing quick edits of programming.

Currently IncrementalLoading doesn't work when setting ListView/GridView's ItemsPanel to StaggeredPanel (or other custom panel)

The Action property is an int for some reason, but appears to just be a CollectionChange enum. It should use the enum as its type instead of an unknown int value.

Created a custom attached property for Page elements.
Added PropertyMetadata via PropertyMetadata.Create so I could specify a CreateDefaultValueCallback handler.

When using the custom attached property, my CreateDefaultValueCallback handler gets called over and over again, it doesn't appear to ever set the value of the attached property. I can have two lines of code, one right after the other that are both calling Get(PropertyName) on the same object/property, and each time my default value callback is executed.

I would expect that the default value callback only gets called once, then sets the value for that object/property.

Web view crash with too long URIs
When redirecting from a webpage to a non supported URI that is longer than 2084 characters the Webview will crash without the throwing any exception.
The weird part about this is that if you redirect the webview to a URI starting with http:// or https:// or you send it to a malformed URI (someting:aLotOfText) of the same length it will be able to handle it.

CalcBinding is an advanced Binding markup extension that allows you to write calculated binding expressions in XAML, without custom converters. CalcBinding can automatically perform bool to visibility conversion, inverse your expression and more. CalcBinding makes binding expressions shorter and more user-friendly.

This is only available for WPF - https://github.com/Alex141/CalcBinding

Here are some examples

<Label Content="{c:Binding A+B+C }" />

<Label Content="{c:Binding A*0.5+(B.NestedProp1/C - B.NestedProp2 % C) }" />

<Button Background="{c:Binding '(A > B ? media:Brushes.LightBlue : media:Brushes.White)'}"/>

<TextBox Text="{c:Binding 'Math.Sin(Math.Cos(A))'}"/>

<Button Visibility="{c:Binding !IsChecked}" />

<c:Binding 'A and B or C' />

For 1803, I like that the backbutton is now built-in to the NavigationView control. However, the placement of the button looks terrible next to the hamburger button.

I was actually excited to see it was built into the Nav control because i can't figure out where to place the backbutton either such that it doesn;t look weird and out of place... but, the built-in nav backbutton doesn't solve the problem either... it still look weird and extreme beta...

The Windows Imaging Component WICBitmapInterpolationMode enumeration has supported the value WICBitmapInterpolationModeHighQualityCubic since Windows 10 was first released. However, the corresponding Windows.Graphics.Imaging.BitmapInterpolationMode enum has not been updated to include this value. Please add this value so we can use it in the BitmapTransform of a BitmapDedcoder method for getting pixel data or a SoftwareBitmap.

I'm using an incremental loading collection in a page.

When (and only when) text scaling is set to 125%, neither HasMoreItems nor LoadMoreItemsAsync are ever called.

The weirdest thing is that it works just fine on 100, 150 and 200%.

Currently we have no notifying system to the developers when the customer add new feedback to the feedback hub. We, developers should check the developer dashboard every day and day. It's tooo painful. Is it possible to add the notification system? Just ping by mail is enough. Uservoice already have it.

We can easily create an outlined text in WPF.

In UWP, I only found a way with Win2D, but it will draw like a picture, the layout arranges will not work (such as TextWrapping).

Sometimes you want text trimming to occur from the left or middle like "...some of my text." or "C:\Long Path...\somefile.txt". The TextBlock TextTrimming property should have an auxiliary TextTrimmingPosition property which defaults to Right, but can also be set to Middle or Left to support the same types of scenarios but in the other locations.
