Adding a custom header to instruct browsers on rendering directives (in this case Internet Explorer)

In Classic .NET Do this

<?xml version="1.0" encoding="utf-8"?>
<configuration>
	<system.webServer>
		<httpProtocol>
			<customHeaders>
				<add name="X-UA-Compatible" value="IE=edge,chrome=1" />
			</customHeaders>
		</httpProtocol>
	</system.webServer>
</configuration>

.NET Core

public void Configure(IApplicationBuilder app)
{
    app.Use(async (ctx, nextPipeline) =>
    {
        ctx.Response.OnStarting(() =>
        {
            ctx.Response.Headers.Add("X-UA-Compatible", "IE=edge,chrome=1");
            return Task.FromResult(0);
        });
        await nextPipeline();
    });
}
