Hi imagetech,
Accroding to your description,as far as I think,ASP.NET Core does not support web forms so there isn't any way to just automatically convert an a Web Forms to an ASP.NET Core.
However,it is possible to make the migration. The general architecture of ASP.NET Core is based on MVC so it's much more similar to ASP.NET MVC than ASP.NET Web Forms. So you could end up rewriting pretty much all of your UI code using some derivative
of a MVC pattern. You could use layouts. Instead of server controls you could use tag helpers. Instead of user controls you could use partials and view components. Instead of code behinds you could use controllers and view models. Etc.
It's worth noting that there is still an http context object, request object and response object and they are extremely similar to the analogous objects in web forms. So that helps with the conversion.
Also to make the conversion process easier, you can build an ASP.NET Core web application that targets the full framework. This means that you will have access to most everything you are use to in the full framework except anything in the System.Web namespace.
Targeting the Full framework does mean that your new website will only run on windows. But if you can live with that (at least for now) it will make the conversion process easier for you.
If, in your old website, you broke out a bunch of the functionality into class libraries, that will make your life easier. You should be able to bring those class libraries over to the new website unchanged and reference them from the ASP.NET Core website
and they will most likely work fine provided they don't reference System.Web. Any code that does reference System.Web will need to be modified to use the new analogous objects or UI approaches.
So in the end, you may be able to bring over your data models, data access code, business objects, and business logic without too much hassle. But you will have to do a total rewrite of your UI related code.
Best regards,
