I want to develop a web based 3D application using Cocos3d framework. I see it should be possible, as they are supporting for Java. Why i want to develop using Cocos, because i will use this web based app to launch on iOS and Android devices as Hybrid or Web app solution. I can't use three.js or flash based as both are not supported by iOS and Android browsers. Could someone advise me i can develop this using Cocos3d web app?
You can't. Cocos3d is not part of/not supported by the cocos2d cross platform development framework. It has no Javascript bindings nor is there a html5 version of cocos3d.
I suggest you take a look at Unity or other engines if you want to do 3D web apps.

I have developed an extension for Internet Explorer in C# using Visual Studio .Net 4.5.2 Framework which I would like to port to Chrome & Edge (Chromium). It is quite a sophisticated extension that comprises 6 bespoke C# libraries I have developed which in turn use a number of system libraries including Microsoft.mshtml & System.Windows.Forms. I am hoping that building out as a WebAssembly will prove a viable solution.
I tried porting to .Net 5.0 using Visual Studio 2019 with Windows.Wasm and also using Mono.Wasm but these have simply thrown up a succession of compatibility challenges.
Can anyone recommend alternative approaches I should look at. I am considering trying Blazor (although this appears to be more orientated towards server-side than client-side), Ooui.Wasm and Uno platform.
Regards,
Howard
Blazor has two different types of projects, one is Blazor Server App, which is obviously server side, and another one is Blazor WebAssembly App, which can be used to develop client side browser extension.
I too, has the intention to create browser extension using Blazor and so I created a package to help others achieve the same too. Feel free to checkout my repo on GitHub on how to do it.
This package includes the ability to interact with the WebExtensions API for cross browser compatibility. A browser APi polyfill developed by Mozilla is also loaded so that you can use WebExtensions API in Chrome too.
However in your scenario, with Blazor it is not possible to use WinForms so you will have to convert them to Razor components.
I'm planning to build Web application and use the SignalR library to allow web admin to chat with other users (use Mobile application)
1- System admin uses Web Application built by Asp.net Boilerplate (.NET Core 3.1).
2- other users use Mobile Application built by (Qt Mobile application )
So, Is this scenario applicable with the SignalR library, or I will encounter some limitations especially with QT Mobile application?
Update:
Why I want this approach?
Because I'm using Esri QML SDK (in Mobile App)
I am not familiar with QT Mobile Application development, however I looked for it and understood that the language of development is C++.
Based on this, here is a client lib for SignalR in C++. You can use this lib to connect to c++
Click Here
Also, I wish to bring attention to an official documentation from Microsoft that states that C++ & Swift are unofficially supported framework.

I have not used SignalR before. However, Qt provides its own websocket QML client component as well as a server one, they have a client example here and a server example here should you want to see how the client component interacts.
I have used the QML websocket with a NodeJs websocket server and it presented no problems at all.
Creating a simple working environment should be no problem, Qt provides its own simulator with their IDE, just copy the client example, change the link to point to your server and give it a shot.
If you haven't got this up and running by now, I'll suggest you would take a look at signalr-qt. We have been using this for several years now, with Qt apps for iOS, Android and Windows desktop. Unfortunately it is not maintained anymore, but we've been running it in production apps using Qt 5.6, Qt 5.12 and Qt 5.15.
Is UWP or Xamarin is usable for enterprise applications like CRM, ERP, etc...
Is the any sample on market, or there are any patterns?
These platform are firstly mobile platforms, but they had a excellent support, a lot of graphically possibility and very modern look and feel. These platform are designed for mobile application in first line, but they are ready for enterprice applications?
Of course the are lot of extension in built control (DataGrid, Charts) which makes possible to create enterprise application. But I did not find any. Is there and problem or drawback of this platforms?
Thank you
Is UWP/Xamarin ready for enterprise applications?
The answer is yes. Xamarin UWP applies not only to mobile platforms but also to desktop platforms(Windows 10). You could also run it in the desktop client. This benefits from the native universal window platform.
For pattern, there many pattern you could select such as publish-subscribe MVVM etc. For more you could refer Enterprise Application Patterns using Xamarin.Forms.
For enterprise publish, you could think of Xamarin UWP application as UWP application, and Distribute LOB apps to enterprises document has described the details of publish process.
And this blog describe the possibility of Xamarin.Form enterprise application that you could refer.
I am using Visual Studio 2017 to create a Xamarin Forms application that supports Android and iOS. I am new to Xamarin.
I would like to use scalable images on both platforms. I am starting with the Android side, and I want to use the newer VectorDrawable format.
Is it possible to use the native VectorDrawable support (with backward compatibility provided by the AppCompat library) in a Xamarin Forms app?
I have seen solutions that use svg images, and other rendering libraries, but I would like to know if I am missing something regarding Xamarin Forms before I go down an alternate road.
I have been throught a lot of reading and the whole thing is becoming only more confusing so I decided to ask you some stuff about Flex.
So, Flex can run in a webpage if you have Flash plugin in your browser, in an AIR container (on pc/android/IOS, but on OSX ?) and also can compile to Native IOS/Android app.
I am not sure about the last point.
If it is possible, how can I build a flex app that would run in browser with flash plugin and also be compiled to Android and IOS (and maybe Windows RT) ?
Adobe gives you Flash builder, do you also need the Flex SDK ? Is it doable with the Eclipse Flex plugin ?
Thank you for your help and sorry if it is a bit messed up.

This is mostly correct. Flex can run in a web page using the Flash Plugin, which is widely available on desktop browsers. For all intents and purposes, you should assume your mobile users do not have a Flash Plugin installed on their mobile browsers.
It is true using AIR you can create desktop applications for PC and Mac; OSx is indeed supported. You can also use AIR to create Mobile applications on Android, iOS, and Blackberry Playbook. So, iOS is indeed supported. Windows 8 UI/Metro support for AIR is expected 1st quarter of this year. I suspect we'll also see AIR support for Blackberry 10; but nothing has been formally announced that I'm aware of.
Update: 3/2014
Adobe has abandoned plans for Windows 8 UI / Metro support. Windows Phone 8 support is a very common feature request, though, so vote for it if you want it.
BlackBerry 10 does indeed support Adobe AIR. Here is a link to the SDK.

browser with flash plugin and also be compiled to Android and IOS (and
maybe Windows RT) ?
Flex is primarily a framework for creating business applications. A slightly different component set is offered for desktop applications and mobile applications. Part of this is due to screen size; and part due to performance. A big DataGrid with dozens of columns, for example, is not conducive to the screen size of your mobile phone.
Update 3/2014:
A mobile optimized DataGrid was donated to the Apache Flex Team, and it should be available in current versions of the SDK.
In the end; you should not plan on using the same exact application for both your Desktop/browser app and the mobile app. But, you can share some amount of code. I would target to share 80% of the code. Move the shared code into a library project; which you can then use on both your mobile application, your desktop application, and your browser based application.
Adobe gives you Flash builder, do you also need the Flex SDK ? Is it
doable with the Eclipse Flex plugin ?
Flash Builder is shipped with the Flex SDK. And Adobe Flex ships with the AIR SDK [Note: Apache Flex does not ship w/ the AIR SDK due to licensing differences; but there is a handy installer]. Flash Builder, also, is an Eclipse plugin and can be installed into any eclipse instance you wish.
You do not need Flash Builder to create a Flex Application. You can use command line tools and other IDEs, such as IntelliJ, if you prefer.
Using Flash Professional, you can package and export to a number of platforms using AIR. You can port to both Android or iOS (as a native app), in addition to creating a .swf file that can be embedded onto a webpage - all using the one application (go 'File' > 'Publish Settings' then change the player target).
I'm not sure whether the same options are available in Flash Builder, (appears to be possible -
adobe website) but not other IDE (such as Eclipse) or framework should be needed.
You may want to consider an alternative development and deployment strategy depending on your requirements, e.g. PhoneGap which should offer support for a greater number of devices.
