Solution 1:[1]

In case you are looking just how to update from @Html.Partial to <partial>:

    @Html.Partial("AdminPartials/_TopMenu")
    @Html.Partial("AdminPartials/_Sidebar")

Should be changed to

    <partial name="AdminPartials/_TopMenu" />
    <partial name="AdminPartials/_Sidebar" />

For the ones how as me are not so familiar with regex. You can do this change easily in whole solution using Find&Replace. It should do the job in most cases.

Find: \@Html.Partial\(\"(.*?)\"\),

Replace: <partial name="$1" />,

option "Use regular expressions" checked

and

Find: \@Html.Partial\(\"(.*?)\", (.*?)\),

Replace: <partial name="$1" for="@($2)"/>,

option "Use regular expressions" checked

Solution 3:[3]

use

@await Html.PartialAsync("_partialView", new List<Model>())
