Protobuf-net on Windows Phone 8 - windows-phone-8

I try use Google protobuf in my WP8 application. I use protobuf-net for my purpoces. When I generate my proto.cs file from qwerty.proto I see next string (below)
...
[global::System.Serializable, global::ProtoBuf.ProtoContract(Name=#"Query") ]
...
But WP8 SDK has not Serializable in System namespace.
May be I made a mistake when I generated proto.cs via protogen.exe? May be it has any additional parameters?

If you use protogen -p:help it will show you the options available not just for the tool, but: for the template you are using (csharp by default). The one of particular interest here is lightFramework. So add -p:lightFramework and you should be set.
Also: for the best performance on phone 8, you may also want to look at precompile, which allows it to use static IL rather than reflection. This is discussed more here.
Note that with protobuf-net it is not required that you start from a .proto file, but that usage is supported; it also works fine "code-first".

Library class doesn't know of ConfigureWebHostDefaults extension method

I'm building a suite of REST micro-services using .Net Core 3.0 Preview 6. All these services will have the same start up logic. So, I'm trying to place all the code in a .Net Standard library.
The goal is to have the IHostBuilder:CreateHostBuilder method, as well as the Startup:Configure and Startup:ConfigureServices class and methods in the library. The library will also contain error handling logic, customized http response messages, etc.
However, I can't seem to find the correct package that contains the ConfigureWebHostDefaults method. I tried adding the Microsoft.AspNetCore package 2.2.0, but that didn't resolve the issue.
I added the Microsoft.Extensions.Hosting (3.0.0-preview-6) package, that also doesn't resolve the issue.
Is what I'm attempting even possible?
Thanks

I resolved it, not the best way, but it works. I decided to make the library targeted specifically for .NET Core 3.0. So, I changed the targetframework in the project file. That change automatically resolved my other issue.
Import the Microsoft.AspNetCore package, and use WebHost.CreateDefaultBuilder() instead. According to the code it is built from, both CreateDefaultBuilder() and ConfigureWebHostDefaults() call the same internal method: ConfigureWebDefaults().
The only downside of this is that the returned host will be an IWebHost instead of an IHost.

Is there a way to force the UWP RichEditBox use only UTF encoding when the user types?

I am trying to convert the contents of a UWP RichEditBox to HTML.
For that purpose, I've tried using the RtfPipe library (https://github.com/erdomke/RtfPipe). From the looks of it, this library has a problem on UWP, due to the fact that not all encodings are defined on that target framework. (This is the error you get, if you are interested: Encoding.GetEncoding can't work in UWP app, but the accepted answer seems not to be the best option on all platforms - I haven't even managed to make the suggested fix compile, so it might not be valid anymore)
Now, as a way of avoiding this from happening, I am wondering whether there is a way to force the control to always use one of the UWP-defined UTF-variants for encoding the data when the user types his text.
Because, now, when I type into it, I get things like that:
{\rtf1\fbidis\ansi\ansicpg1253\deff0\nouicompat\deflang1032{
....
\pard\tx720\cf1\f0\fs23\lang1033
...that make the library throw exceptions.
I guess, if I manage to make it not use ASCII code pages, things will be great.
After taking a look at the control properties though, I do not see something I could use. Is there any way to achieve this?
This is the error you get, if you are interested: Encoding.GetEncoding can't work in UWP app
As you described, there is an inner error thrown when using this package with UWP app. System.ArgumentException: 'Windows-1252' is not a supported encoding name, by testing on my side, which is thrown by the code line public static readonly Encoding AnsiEncoding = Encoding.GetEncoding("Windows-1252"); of RtfSpec.cs when UpdateEncoding.
It seems like Windows-1252 may not be supported in UWP from the error details,also see this similar thread. You could use UTF instead as you want, for example, have a change on the library with following then it will work (testing demo here).
public static readonly Encoding AnsiEncoding = Encoding.UTF8;
I haven't even managed to make the suggested fix compile, so it might not be valid anymore
Encoding.RegisterProvider method should be work, but it only support UWP or .NET Framework 4.6, it does't support the Portable Class Library. The RtfPipe library you mentioned is Portable Class Library, so that you cannot use Encoding.RegisterProvider. Encoding.GetEncoding method supports Portable Class Library, details please check the version information of the two classed.
I guess, if I manage to make it not use ASCII code pages
RTF itself uses the ANSI, PC-8, Macintosh, or IBM PC character set to control the representation and formatting of a document, you may not able to change that. Consider to update the library to resolve the issue for UWP.

MvvmCross 4 support for UWP, AppShell missing Frame

I have created a new solution for my MvvmCross app that supported Windows Store and I want to support UWP on Windows 10. I have moved over the PCL successfully, but I am having problems getting the basic UWP app working using a sample provided by MS (NavigationMenu) which uses the SplitView and the AppShell pattern they are recommending for the new navigation/command model. I referenced a helpful blog post (http://stephanvs.com/implementing-a-multi-region-presenter-for-windows-10-uwp-and-mvvmcross/), which gave me some guidance on how to integrate mvvmcross into the AppShell, but startup is failing because the AppShell does not have a valid Frame defined. Frame is a read-only property, and I have been unable to see where this is being set up.
I am using the standard AppShell implementation from the NavigationMenu with the following changes as recommended in the blog post:
public sealed partial class AppShell : MvxWindowsPage // was Page
public Frame AppFrame { get { return this.Frame; } } // was this.frame
Except for code after the error, there are no differences in the setup. In looking at the MvxWindowsPage implementation, there doesn't seem to be anything special as it still invokes the Page initialization. Is there something obvious I am missing?
So the link to the blogpost is correct, in other words you'll need to use MultiRegions from MvvmCross to get this working.
But what the blogpost doesn't show is a complete working version...
I've added one on my github here:
https://github.com/Depechie/MvvmCrossUWPSplitView
Some pointers to take away, like I said in the comments.
Your view where the SplitView will be present, needs to have a property to return a valid Frame to look for while injecting new views. This can be returned like this return (Frame)this.WrappedFrame.UnderlyingControl; found in the code here https://github.com/Depechie/MvvmCrossUWPSplitView/blob/master/MvvmCrossUWP.Win/Views/FirstView.xaml.cs#L13
Than all views you want to load up in the SplitView will need to reference to the region you defined in that SplitView, in my case I named it FrameContent as seen here https://github.com/Depechie/MvvmCrossUWPSplitView/blob/master/MvvmCrossUWP.Win/Views/FirstView.xaml#L48
So use that name for the region attribute in all to be loaded views like so [MvxRegion("FrameContent")] example here https://github.com/Depechie/MvvmCrossUWPSplitView/blob/master/MvvmCrossUWP.Win/Views/SecondView.xaml.cs#L7
I see what you're trying to do with the SplitView template that's provided by Microsoft. There is however a mismatch between things managed by MvvmCross and UWP.
By default MvvmCross maps ViewModels to Views based on naming conventions. What you are trying to do is use a view 'AppShell' (which is derived of Windows.UI.Xaml.Controls.Page) that doesn't adhere to the default MvvmCross convention.
The way I choose to implement this SplitView (Hamburger) functionality is by deleting the provided AppShell class entirely. I then created a new view named HomeView (since I have a ViewModel with the name HomeViewModel) and added the SplitView control there as described in the post you mentioned above.
For completeness I've created a Gist with the App.xaml.cs and HomeView.xaml as you requested. You can find them here: https://gist.github.com/Stephanvs/7bb2cdc9dbf15cb7a90f

How to activate IWiFiDirectDevice in Win32 Console APP using WRL?

I want to use WinRT API for WiFi Direct from Windows 10 SDK in Win32 Console Application. I know about C++/CX (and even made some progress going that way), but still want to make it work without this extension.
My problem is that I can't activate IWifiDirectDevice interface (from ABI::Windows::Devices::WiFiDirect) to access IWifiDirectDeviceStatics that provides an GetDeviceSelector method.
HStringReference strDevice(RuntimeClass_Windows_Devices_WiFiDirect_WiFiDirectDevice);
ComPtr<IInspectable> insp;
hr = RoActivateInstance(strDevice.Get(), insp.GetAddressOf());
This code ends up with E_NOTIMPL as a result. In Microsoft's example they used factories for activation, but ABI::Windows::Devices::WiFiDirect namespace has no factories.
Worth mentioning that IWifiDirectAdvertisementPublisher works just fine when activated the way I wrote before.
So how to activate IWifiDirectDevice from WRL?
Windows.Devices.WiFiDirect.WiFiDirectDevice is not an activatable class. You can see that by looking at windows.devices.wifidirect.idl.
You will need to use the static methods, e.g.:
HStringReference strDevice(RuntimeClass_Windows_Devices_WiFiDirect_WiFiDirectDevice);
ComPtr<IWiFiDirectDeviceStatics> wiFiDirectDeviceStatics;
hr = Windows::Foundation::GetActivationFactory(
strDevice.Get(),
&wiFiDirectDeviceStatics);
ComPtr<IWiFiDirectDevice> wiFiDirectDevice;
ComPtr<IAsyncOperation<WiFiDirectDevice*>> asyncOperation;
hr = wiFiDirectDeviceStatics->FromIdAsync(deviceId.Get(), &asyncOperation);
Consider taking a look at the Wi-Fi Direct sample.

getWindowHandle function doesn't exist for driver in Selenium

I need to implement switch from one window to another in IE. However, element driver doesn't support getWindowHandle function.
I assume it might be just configuration problem or settings, though I don't know how to fix it.
Please, any suggestions.
I'm working with c# - Visual Studio
You haven't said which language bindings you're using, but based on a comment you posted, it looks like you're using C#. The method names are slightly different for each language binding. From this answer:
The object, method, and property names in the .NET language bindings
do not exactly correspond to those in the Java bindings. One of the
principles of the project is that each language binding should "feel
natural" to those comfortable coding in that language.
So you have to do a little translation if you're trying to copy-paste Java code. In this case, you want the combination of the WindowHandles property (to look for the new window handle) and the CurrentWindowHandle property of the driver. You can find full API documentation for the .NET bindings at the project's Google code site.
I am going to make wild guess:
Try to initialize your driver like this:
WebDriver driver = new FirefoxDriver(); //assume you use firefox
The interface WebDriver supports that method. Do not forget to store the handle somewhere ;)
String myWindow = driver.getWindowHandle();
BTW that method should return you actual window If you need all windows you probably should use getWindowHandles() method
If this does not work, please provide more info:
what error exactly are you getting?
How do you initialize WebDriver?
