描述

public class A: B{
    public override int Q{ set{ base.Q = value; } }

    public void foo(int x){
    }

    public void test(){
        foo(Q);
    }

    public static void Main(string[] args){
    }
}

public class B{
    public virtual int Q{ get; set; }
}

Calling model.GetSymbolInfo on the argument 'Q' in the call to 'foo' returns an IPropertySymbol defined by class A, which does not have a GetMethod. To get the GetMethod used, I have to look at the OverridenProperty attribute of the returned symbol to find B.get_Q.

It seems like Roslyn should bind the 'Q' expression directly to the B.Q property. Presumably this does not occur because Roslyn does not take the context of the property into account, meaning that it doesn't look at if the property is used in a get/set context, and rather that simply the name is resolved to the 'closest' definition of the property.
