Is it possible to use server side include in Razor view engine to include .html or .asp file? We have an .html file and .asp files that contain website menus that are used
Why not include a section within your _Layout.cshtml page that will allow you to render sections based on what menu you want to use.
_Layout.cshtml
@RenderSection("BannerContent")
Then, in any page that uses that layout, you will have something like this:
@section BannerContent
{
@*Place your ASP.NET and HTML within this section to create/render your menus.*@
}
