Ninject.MVC3 and Ninject.Web.MVC3 merged to one package

I installed the new ninjectMVC3 using Nuget. I get this error:

Server Error in ‘/’ Application.

This method can only be called during the application’s pre-start initialization stage.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: This method can only be called during the application’s pre-start initialization stage.

Hi, would you please update the package and rename/fix the AppStart folder in the current Ninject package to App_Start. The convention all the other packages and David Ebbo uses is App_Start. Thanks!

What if I have an exception in RegisterServices (which is called by a PreApplicationStartMethod) and I want to log it? I need to Server.MapPath the file path but HttpContext.Current is null..

Any ideas?

Thanks.

God what a mess. I’m a Ninject newbie but can’t find a simple canonical example of how to get it working with MVC3, and the ninject.mvc3 nuget package seems to make things worse.

Fuck this I’m going home.

Which is correct, this blog post or “Setting up an MVC3 application” on GitHub (https://github.com/ninject/ninject.web.mvc/wiki/Setting-up-an-MVC3-application)? When you say, “This means that you have to specify your modules and bindings in this file [NinjectHttpApplicationModule.cs] now and not in AppStart_NinjectMVC3.cs anymore.” Is that still true? And if it is true, why doesn’t the nuget package install a NinjectHttpApplicationModule.cs file? This is very confusing.

Gotta say, “Awesome work on the MVC3 Extension”. I am new to Ninject but have been building smaller MVC apps for a while now, and ignorantly thinking, “I don’t need all that other complication to my apps”. Well i finally broke down tonight and gave Ninject a shot with your Plugin. After compiling, I ran the test app in the browser, just waiting for an error screen…… Needless to say I got the home page of the test app and everything I requested was working just fine to my amazement. I quickly realized that my apps were actually more complicated without it.

Thank You for making my life a lot easier.
