Note: This may or may not be specific to ASP.NET Core.

Currently, if middleware upstream sets the Content-Length header (i.e. StaticFiles), then usage of WebMarkupMin results in a 200, but no content. This is because the resulting content-size is no longer the same as reported by the header-value. My current resolution is to insert my own middleware to remove the header:


app.Use(async (context, next) =>
    await next();

    if (context.Response.Headers.ContainsKey("Content-Length"))


A bit more info. is posted here.

Hello, Bill!

In WebMarkupMin 2.2.0 fixed this error.

Thanks for information! Instead of removing the Content-Length HTTP header, I change its value.
