I have developed a WPF user control and I want to use it in ASP.net.
You can't. ASP.NET and WPF are completely different technologies. Best you could do is provide an XBAP application from your ASP.NET application, which is downloaded and run client side as a WPF application. Even if you convert it to Silverlight, it's still running client-side, with the advantage that Silverlight is a lighter runtime and is available on some non-Windows platforms.
You cannot use it directly.
You can either create an XBAP or you convert the control to Silverlight.
You probably can if you use it in Silverlight.
simply make a little "Silverlight" application and explicitly place on your ASP page. probably you can't do in placing wpf in ASP because the compiler is not teach to read Xbap with knowledge base (extension) of ASP XD

My software is splitted into 2 parts:
ASP .Net Core 3.1 application which is hosted on server
.NET Framework 4.8 WinForms applicaŠ½ion which is deployed on client PC (I can try to place it on server if this greatly simplifies the solution of the problem). The reason why I need this separate application is third-party control that is available only for .NET Framework desktop - WinForms and WPF (unfortunatelly I cannot avoid using or replace it).
Is it possible to run that client PC application inside ASP Net Core HTML page?
I don't need just launch it with System.Diagnostics.Process or similar techniques, I want I want to embed it in a ASP frame somehow. Something like WindowsFormsHost for WFP or ElementHost for WinForms.
Any help is appreciated. Thank you in advance.
Basically, you have these options:
Wrap your desktop app into ActiveX, use IE Tab extension (or similar one), and run ActiveX on the page. The worst one because of, well, ActiveX. In fact, you will not be able to use modern browser features.
Throw away Web UI. If you need desktop app (it doesn't matter why), then use desktop app and Web API at server side. The easiest and obvious one. You're still linked to desktop, so what is the reason to ignore this fact?
Render mentioned control's output at server side, and send the result to browser. This depends on what the control is, what it does, how much interactivity it requires, etc. Also, this assumes, that you must be able to run .NET 4.8 process on your server and communicate with it from .NET Core app.
I am new to .NET so I have a basic question to ask, is there a way to add Windows Forms application to my web page, as creating forms was easy and I created my app in the form format now I want to add them to asp.net page.
It's a different thing, but you might want to look into the silverlight out-of-browser technology.

Spend good time on w3schools.com learning about <form> tags..
then gradually move on towards processing data at backend using C#
a good starting point can be http://www.deitel.com/articles/csharp_tutorials/20060128/index.html
Long way to go..first get your basics right!!
If you have basic knowledge of html, then you can learn the basics of asp.net too. Then you can easily create a web form which exactly matches your windows forms. But always keep it in mind, webforms are not as flexible as windows forms.
well... there are something you can do that is similar.
You can add your windows-form to an BHO and install it in you webBrowser as an ActiveX object (for a IE) or extension (in other browsers), and then share it to everyone you want. Then your win-form application can start and interact with your web-page.
You can start looking here: http://msdn.microsoft.com/en-us/library/bb250436(v=vs.85).aspx
hope it help.
Windows form cannot be added in a web form. They altogether are a different technology. You can add link in your web app for downloading Windows app.
This is what I need to do.
I must create an ActiveX (IE add-on) in C# to show image(s) on client (load image(s) from Twain Scanner).
I have made Windows Form and use System.Windows.Forms.PictureBox but it need .NET framework installed on client PC.
Any ideas are appreciated. Thanks so much.
Everything written in C# requires .NET framework to run. Either the full framework or Silverlight.
If you want to write an ActiveX that is independent of the .NET Framework you have to write it in another language, such as C++ or Visual Basic 6.
I'd recommend that you really, really, really try to get out of the ActiveX requirement and instead use AJAX or Silverlight.
If you use C# to create an ActiveX control, then yes: it will require the .NET framework at the client. You cannot change that.
If you want a non-.NET control, VB6 (though obsolete) may be simplest. AFAIK Silverlight does not offer access to scanners, so is not an option.
I also suggest, however, that ActiveX itself is already imposing a lot of demands (mainly: IE). I wonder if something like a ClickOnce client application is more appropriate. Or: just provide upload (input type="file") controls.
I have a WPF/C# application.
It contains some .XAML pages.
i would like to integrate this application into my ASP.NET/C# web application.
I want the application to show in an asp.net page.
What is the best way to do this?
I heard that I can use Silverlight.
I never worked with silverlight before. Can I do it without knowing silverlight or should I have a knowledge in silverlight before doing it?
Any help is greatly appreciated.
Thank you very much
You can either deploy your WPF application as an XBAP or migrate it to Silverlight. I'd recommend the latter because you'll get better browser/os support.
Just create a new Silverlight project and copy your xaml files into it. Probably, everything will be compatible since both frameworks have a lot in common. Silverlight is a bit more restrictive since it's a web framework, but it also has other features that WPF doesn't. If you find something that's not compatible, just search for an alternative here.
I want to start silverlight development inside an application which developed by WPF.
Actually we want to add silverlight featuretoan existing WPF project. what should we consider and how todo this
I saw Getting started with Silverlight development and it was not my answer
I mark this as a Community Wiki.
Please clarify your intent. What do you mean by a Silverlight feature ?
Silverlight is a subset of WPF, but is intended for a Web application (i.e. running inside a Web browser, using the .NET framework provided by the browser plug-in), while WPF is meant for a desktop application (i.e. running outside of a browser, using the full .NET present on the disk).
(there is the notion of running WPF inside the browser, but that is still using the full .NET framework).
"Adding" Silverlight to WPF doesn't make much sense because you can accomplish whatever you need to do in regular WPF for the most part. If you already have a WPF application you are enforcing windows and the full .NET client run time so you are going to get any deployment benefits.
I assume what you may be considering (since you mentioned XBAP) is to re-write or recompile your current WPF XBAP application into a Silverlight application? This way you get cross platform web deployment with the full Client run time requirement.
If this is the case then you would not be "adding" to your existing solution. It would be more an exercise in porting the existing application over to Silverlight. With SL3 this is less painful then before (and if SL 4 is an option it will be an even better experience).
My first step would be to simply create a new Silverlight application and begin moving your code over and seeing how far you get.
