Custom css file is missing in published app

Hi,

I've published my asp.net core 2.2 app and can see my Style.css file is missing in "css" folder in wwwroot. Any ideas why it's that? Am I supposed to use custom css file or all css must be in site.css? I found a bit similar topic but there the poster used site.css and found that publishing wasn't updatinng site.css.min file. The solution was to use BundlerMinifier. Since I'm not using site.css I don't think this might work for me too. Did anyone else encountered that?

I also used resources files to customizing my app to different cultures (like english, german, etc.) and I see there are appropriate folders created (like "en-US") with Texas.resources.dll file in each, but I can't change the culture the way I did in debug environment on my pc. Here's the method I'm using to change the culture, apparently it's not triggering in published app:

public async Task<IActionResult> OnGetSetCultureAsync(string culture)
{
HttpContext.Response.Cookies.Append("Culture", "c=" + culture + "|uic=" + culture);
var returnUrl = Request.Headers["Referer"].ToString();
if (returnUrl.Contains("?culture="))
{
var url = returnUrl.Substring(0, returnUrl.IndexOf("?culture="));
return Redirect(url + "?culture=" + culture);
}
else
{
return Redirect(returnUrl + "?culture=" + culture);
}
}

Btw, you can github my project here
