I need one Action return a JavaScript fragment.
In MVC 5 we have:
return JavaScript("alert('hello')");
but in MVC 6 we don´t.
Is there a way to do this now ?

This can be achieved by returning ContentResult MSDN
return Content("<script language='javascript' type='text/javascript'>alert('Hello world!');</script>");
or other way would be making use of ajax
return json(new {message="hello"});
$.ajax({
url: URL,
type: "POST",
success: function(data){alert(data.message)},
});

Can you please include an explanation with this as well. Code only answers are typically frowned upon because they lack reasoning. Perhaps include a link to MSDN or something that references Content?

The first option does not work with mvc 6. Nothing happens, at all.

Can you add more to your code rather than a simple return statment, client side, controller code. I would prefer second option though.

Actually I need to render a partial view and present it in a bootbox control.

where do I put the ajax code. I don't have a view. I just want to display alert.
I think we can implment JavaScriptResult ourselves since it is not supported officially. It is easy:
public class JavaScriptResult : ContentResult
{
public JavaScriptResult(string script)
{
this.Content = script;
this.ContentType = "application/javascript";
}
}

In your controller you must be add: public class JavaScriptController : Controller { public IActionResult Index() { return new JavaScriptResult("var jjj=123;console.log(jjj);"); } } in html page you must be add: <script type="text/javascript" src="/JavaScript/Index"> </script>
Currently ASP.NET MVC 6 doesn't support JavaScriptResult like in MVC 5. An interesting discussion for this can be found here (there's some solutions for your problem too): https://github.com/aspnet/Mvc/issues/2953
Personally I think that sending JS code to the client is a bad thing (send the client the data that the JS needs and then perform the functions invocations there) but it seems that there's a valid situation for this (look at the last comment).

This will be a challenge for my actual project. But I will give a try.

Sending??? No! It should be used for sharing of dynamically create JS using site endpoint. For example for dynamically created constants.
