In Tokyo Game Show 2017, 東プレ will have a typing tournament “REALFORCE TYPING CHAMPIONSHIP 2017”. And they use the Weather Typing. 東プレ makes a famous keyboard Realforce which is widely used among typers. Of course I am a user, too.

A while ago, Pocari told me about the tournament and asked me to allow to use Weather Typing and I responded yes. It seems that was decided. Thanks to use Weather Typing every time. I have not thought such an event 15 years ago when I saw TOD event in Akihabara.

After using WT3 twice in Typing Summit and I fixed up some bugs so timing is so good. It will be a one on one battle via LAN so I do not have any concerns but please tell me if you know any bugs of current version.

It will be another event in next week, the download count of Weather Typing will be higher.

The bottle neck of porting Weather Tpying (WPF) to UWP is native C++ DLL. It is not difficult to port C++ code to C# but it will be convenient if I can use native code, it will be good.

At first, I tried making native DLL and called it from UWP by P/Invoke, it succeeded. It worked in Windows IoT, too. It seems that without prohibited API, it works.

After that, I tried building it as Windows Store app and validated with Windows App Certification Kit (WACK). Then I got “vccorlib140.dll is not supported for this application type” and Windows Security Features Test failed. In the error, memset and memcpy, that seems no problem to use, were shown. It
seems that the native DLL is linking desktop app library.

I found “Consume Windows Runtime Extension” in Native DLL project property. I enabled it seeing “Using C++/CX in Desktop apps” but it doesn’t change.

At last, I found official help “How to: Use Existing C++ Code in a Universal Windows Platform App” and changed project file directly and changed pre-complie header name addition to C++/CX settings above. After that, WACK succeeded.

When I saw the generated DLL by Dependancy Walker, it linked to “VCRUNTIME140_APP.DLL” and “MSVCP140_APP.DLL” instead of “VCRUNTIME140.DLL” and “MSVCP140.DLL. ” APP-DLL may be for UWP.

Followings are the tips I got using Xamarin.Forms for several days.

1. Can’t build automatically with F5

The project runs immediately with F5 so I did build & deploy manually in each debug. But I found the checkbox of [Configuration Manager]-UWP project build and deploy, Is it off as default?

2. I got exception in Release mode

I get System.PlatformNotSupportedException: ‘Arg_PlatformNotSupported’ exception when I run Shared Project MainPage. No exception in Debug mode. When I skip this exception, the app runs well. What is it?

3. Xaml intellisense dead

The worst trouble is this. It works some time but after doing something, intellisense will be dead. In UWP context, I haven’t seen intellisense works correctly. I get error like “ContentPage was not found” and have very little choice of code. In Android/iOS context, it works some time but after some operations, intellisense window does not show. In that situation, after removing shared project reference from Android/iOS project and add them again, iintellisense comes again… or not?
