The type String cannot be constructed

Question

I\'m using Web.api and Unity and I am getting the following error when trying to open the default \"help\" area:

[InvalidOperationException: The type String cann         


        

Answer 1

The reason this happens is because Unity will by default choose to use the constructor with the most parameters thus bypassing the default constructor.

Comment out the two constructors that exist in the HelpController template and add a default one that sets the configuration.

    //public HelpController()
    //    : this(GlobalConfiguration.Configuration)
    //{
    //}

    //public HelpController(HttpConfiguration config)
    //{
    //    Configuration = config;
    //}

    public HelpController()
    {
        Configuration = GlobalConfiguration.Configuration;
    }
