StaticContextClaimsProvider for DXA .NET. This lets the web application use some of the basic Context claims without a dependency on the SDL Web Context service or the Context ADF cartridge.

        {
            IDictionary<string, object> claims = new Dictionary<string, object>();

            // These claims are part of the claims which the ContextServiceClaimsProvider would return for a laptop with 1600x900 screen
            claims.Add("ui.largeBrowser", false);
            claims.Add("browser.displayHeight", 529);
            claims.Add("browser.displayWidth", 1280);

            claims.Add("device.displayWidth", 1280);
