```

## GetMember

```csharp
Expression<Func<Foo, int>> propertyExpression = x => x.BarProperty.BarId;
var result = propertyExpression.GetMember(); // gives MemberInfo instance for BarId
```

```csharp
Func<Foo, Bar> func = x => x.BarProperty;
var result = func.MakeNonGeneric(); // gives instance of type Func<object, object>
```
