The model item passed into the dictionary is of type 'nsroute.DataAccess.User', but this dictionary requires a model item of type 'nsroute.BusinessObject.UserBO'.

Hi,

So Yash, basically the action ActionResult SignUp(User obj) has an input model(parameter) of type User which is defined in the namespace nsroute.DataAccess.
When this action retuns a view, it is passing the obj of type User. While you have defined your view's model as :
@model nsroute.BusinessObject.UserBO
which is an issue.

So either pass UserBO as a parameter to your view:

public ActionResult SignUp(UserBO obj)

{

if(obj != null)

{

return View(obj);

}

else

{

return View();

}

}

OR

Change your view's model to:

@model nsroute.DataAccess.User

Thats it. Try it out.

Hi,

Your view with model name and sign up method of controller not have same object. You are using different model in view and action method.

Please correct it will start working.

The error is self explainatory your view is strongly typed with UserBO but you are passing User object from Action to view, use the same type at both places either use User object in both Action and view or use UserBo at both the places Action and view.
You are confused because you have generated your entities in DataAccess layer where there is a User entity and you have also created a UserBO in business layer perhaps.
so, you are getting error because of namespace, namespace usually means the folder name where your entity resides.
