my resource provider inherits markup extension 1 property: key.

thanks advice

you can create custom markup extension using following code :

public class localizedbinding : markupextension {     public string key { get; set; }      public override object providevalue(iserviceprovider serviceprovider)     {         iprovidevaluetarget target = (iprovidevaluetarget)serviceprovider.getservice(typeof(iprovidevaluetarget));          //use target.targetobject , target.targetproperty provide value based on key     } } 

and use :

<textblock text="{local:localizedbinding key=somekey}" />
