Images all return 404

I've been doing this for about 16 years and I've never had a problem or misinformation and misdirection as I have with something as trivial as adding an image to a webpage.

I created a new MVC site .NET Framework 4.6.2 with Individual user accounts and I also added angular

and am serving up partial razor pages and angular through the area section.

I tried to place an image into the _Layout and couldn't get it to work, then abandoned that to just put an image in a <div> in one of my partials.

<div style="padding-top:25px">

I'm the Test page

<img src="~/Content/WeCare.jpg" /><img src='<%= Url.Content("~/Content/Images/WeCare.jpg")%>' alt="Test Pic" /></div><ui-view></ui-view>

I've tried ever configuration of adding the image and changed the location of the images based on other posts I read and nothing works?  I just get 404's

I've even tried adding...

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {
              app.UseStaticFiles();
        }

to my Startup.cs because someone told me this is what was missing.

How can it be this hard to add an image to a webpage...I must really be missing something or not understand how this works at all?

Thanks for any help, sorry for the frustration.
