Hi,

I just grabbed version 1.0.2 from Nuget and I am have a problem with a Release build of my ASP.NET MVC app.

when I set debug="true" in Web.Config and I put the CssBundle render in the <head> of a Razor view it works as expected.

from web.config

from razor view

@MvcHtmlString.Create(Bundle.Css()

.Add("styles.css")

.Render("styles.min.css")

)

it renders like this

when I change debug="false" in web.config I get the following exception.

Am I missing something?

Object reference not set to an instance of an object.

I reverted back to 1.0.1 and it works as expected.

Thanks for letting me know looks like I fat-fingered something in latest release. Just pushed 1.0.3 it should work for you unless you are in an environment where you need to favor MD5 over SHA hashing for some reason.
