How to call Windows form from .net web application

i have a windows application and now we want to upgrade it to web application.
Is there any way to use same forms from web application
to avoid duplicate work to develop same page in web application.
i want to open windows form on one click from web form. please provide any sample code if possible.

It's not something you can do automatically. You can reuse your business logic behind the application but you have to write a new UI from scratch. You can also try to use some automated tools but to be honest in most cases you will have to put significant amount of work to get your application working the same as window windows application. You must consider and implement new security policy regarding data transfer/presentation in your web app.

As Adjorem said, simply, no. Even if you find a converter it will probably make a mess and you'll need to do a lot of refactoring.

To open your windows app from web app:
You can register your own url protocol to start your application, e.g myfancyapp.
On your website you can create an href="myfancyapp://...". You can parameterize your windows app through a downloadable file with startup infos.
See:
How do I register a custom URL protocol in Windows?
If you want, you can check, if your app is installed with the help of fonts. Install a font (with a special name) with your app installer. You can then check if font is available on your website and display a message "Please install windows app first".

Auto-launching apps using URI associations for Windows Phone Universal 8.1

I have an application named MyApplication. What I am trying to do is to do deep linking.
I would like to associate a link that when click on my Windows Phone 8.1 XAML, the application will be launched with the elements passed.
For example: MyApplication://item/1234 -> will open my application.
I am trying to do this from outside of an application is this possible? for example if I clicked on this link that was in an email, could it be redirected to my application?
Edit:
Here is part of the solution but i am not finding what i really wanted to do:
Uri Activation(XAML)
https://msdn.microsoft.com/en-us/library/windows/apps/xaml/hh779670.aspx
Code:
https://code.msdn.microsoft.com/windowsapps/Association-Launching-535d2cec

You sure can. Create the protocol (something like test:) in your app and deploy it to your machine. Then, in Start>Run type "test:" and your app will load just fine. A link in email? Sure. A link in a web page? Sure. It all works.

Windows 8 phone app linking to other downloaded applications and store

I would like my app to link to other installed apps on the users phone, such as facebook. Once they click the icon/button it should switch from my app to the selected app, the code should check that app is on their phone. If it is open the app, if it is not open the store page, for that app so they can download it.
Is there a way to link or to navigate to the app? or store? (c# and XAML).
Thank you in advance for your help :)

All you need is URI for the app. It will open the app for you and if the app is not available. It will automatically take the user to the store so that he can download it. This will only work if that app has a Uri available.
Here and Here is a list of apps that support Uri scheme
For example, You can open Facebook App by this code
Windows.System.Launcher.LaunchUriAsync(new Uri("fb:"));

Winrt app - navigate to another application

I'm developing winrt (or windows store) application. I would like to navigate to another (installed) application, but I didn't find solution for it. E.g. I have twitter section with tweets and after clicking on some tweet user should be redirected to windows store twitter application directly to clicked tweet. I read How to launch the default app for a URI but there is not what I need. Do you have some experience with this issue please?

How to configure app to use live coonect api in winRT metro app c#?

I want to configure my windows RT application in c# to use live connect API(As per "http://msdn.microsoft.com/en-us/library/live/hh826541.aspx"). If i go to Windows Store Dashboard("https://appdev.microsoft.com/StorePortals/en-us/account/signup/start"), it ask me to register the app on store expecting more details form me with price i think and i don't want to do that as i just want to explore this topic for sample application.i have created package id before..but ti thinks i have lost that link from were i did this.so how to configure my sample application to use live connect API.

The Windows Store Dashboard is the right place, you'll just need to register a name and then you can to the configuration section for Live Services and Push Notifications. You don't need to enter all of the other information until you're ready to publish your app.
