c# - How to create a static instance of a dependency injected class? -

i've defined class takes repository instance sole constructor argument. , created static instance of class, mainviewmodel constructor arguments need specified.

issue:

in order specify required arguments, added irepository argument expected in static instance of mainvm class.

this didn't work expected compiler throwing following errors result of this:

using generic type 'parkingtagpicker.dal.irepository<t>' requires 1 type arguments    parkingtagpicker.models.zone' 'type' used 'variable'   name 'zonedataservice' not exist in current context     

from looking @ errors seems irepository being supplied correct zone type.

does know how correctly define constructor args in situation?

mainviewmodel:

    //irepository instance zone type arg     //(zone model class)     private irepository<zone> _zonedataservice;      public mainviewmodel(irepository<zone> zonedataservice)     {         this._zonedataservice = zonedataservice;     } 

app.xaml.cs:

    /// <summary>     /// static viewmodel used views bind against.     /// </summary>     /// <returns>the mainviewmodel object.</returns>     public static mainviewmodel viewmodel     {                 {             // delay creation of view model until necessary             if (viewmodel == null)                 viewmodel = new mainviewmodel(irepository<zone> zonedataservice);              return viewmodel;         }     }
