I have:

<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />

On validation in http://validator.w3.org/ I get this error:

A meta element with an http-equiv attribute whose value is X-UA-Compatible must have a content attribute with the value IE=edge.

I am working with .NET/Razor and of course locally using IIS. Is there a way to solve this without editing any web.config files? Thanks in forward.

According to this discussion in the W3C, using the chrome=1 part is not allowed.

You can pass the validation by using just like this:

<meta http-equiv="X-UA-Compatible" content="IE=edge" />
