Question

我正在尝试将本地完美运行的ASP.NET MVC3应用程序上传到Windows Azure。

当我将应用程序上传到azure时，它显示为“Ready”。但如果我调用它，则会出现以下错误：

No parameterless constructor defined for this object.

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.MissingMethodException: No parameterless constructor defined for this object.

Source Error: 

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Stack Trace:

有人知道，错误可能导致什么？我正在使用DI Unity Unity Block ..

错误消息指出以下内容：

'DummyAnwendung.Controllers.AccountController'. Make sure that the controller has a parameterless public constructor

如果没有为类定义构造函数，则将创建无参数构造函数。但是，如果使用参数定义构造函数，则不会创建无参数构造函数。

为此类定义参数类构造函数。

Windows Azure，MVC3，没有为此对象定义的无参数构造函数
