Task 05: Consolidate controller actions into a single action

[sayedihashimi]

In the previous task we created a separate controller action, and view, for each category. In this task we want to consolidate that into a single controller action. The views will still be separate, but we will consolidate that in the next task.

The work needed includes:

• Create a new action, let's name it Category, which will be used. This action should take a string parameter which defines the category to be displayed.
• Update the links on the home page to point to the new Category action and pass in the category name as a parameter.
• Delete old action methods in the controller which are no longer needed

Sample of new controller action

public IActionResult Category(string category){
    return View(category);
}

Sample of an updated link

<a asp-controller="Home" asp-action="Category" asp-route-category="hats">hats</a>

I believe the only work needed for this task is to convert @Html.ActionLink to use the new aspnet TagHelpers (i.e. <a asp-controller="Home" asp-action="Category" asp-route-category="hats">hats</a>).

It doesn’t look like all the work is complete here. I’m still seeing “@Html.ActionLink” in the Index view.

Sorry I had not yet pushed the changes, that's why.

It should be all set now. version control in vsmac is still not working for me, so I just used the command line. I commented out the old lines in the code.
