ASP.NET || VsualStudio || 无法加载文件或程序集？ 我能做什么？

Question

I'm trying to use the "login and register" the comes with the MVC 4, when i fill in the register page (User name and passwords fields) and hit the "register" button this exception pop up:

I got this error and i tried a couple of things...nothing seem to work..

I try deleting the reference and adding it again with the correct path - Now Working.

I cant understand why Visual Studio is looking for the dll in this path: "C:\\Program Files (x86)\\" (i have other dll that i reference to it from that folder)

How can i fix this situation ?

Here is the problem :

Source Error:

Line 92:                 {
Line 93:                 var user = new ApplicationUser() { UserName = model.Email, Email = model.Email };
Line 94:                 IdentityResult result = await UserManager.CreateAsync(user, model.Password);
Line 95:                 if (result.Succeeded)
Line 96:                 {

I dont know what this is :

Check the version you have referenced and the version in your GAC. Sometimes if the versions are mismatched it will try to go for the GAC. Check this answer:

Dll in both the bin and the gac, which one gets used?
