Could not load file or assembly or one of its dependencies

I changed some names of namespaces, assemblies in one of existing project (C# and ASP.NET). But when I try to debug it; I get this error.

Could not load file or assembly 'HR' or one of its dependencie开发者_如何转开发s. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040).

I have replaced DFI with HR in the code.

Sometime I have got such error and began to research how to resolve it. After all I just have added such attribute to web.config compilation node:

<compilation debug="true" tempDirectory="c:\temp" >

I hope that this can help and other people.

4) , 5)

Hope this will help you also.

If your project compiles, you may be referencing the assembly in a config file. I would check anywhere that you may be using late binding to reference a type. Also check your @Page directives as you may have an assembly qualified type reference that is referring to the old HR assembly.
