Missed "else" in property setter delegate.

[Rumyash]

I have nullable property

[MyAttribute]
public int? NullableProperty { get; set; }

with simple attribute

public class MyAttribute : Attribute, IPropertyInterceptor
{
    public void OnGet(PropertyInterceptionInfo propertyInterceptionInfo, object value)
    {
        int? newValue = CalculateValue();
        propertyInterceptionInfo.SetValue(newValue);
    }
    ...
}

When the newValue is null and I set it to propertyInterceptionInfo, then the NullableProperty returns 0 instead of null. This is because the "else" is missing in the generated method, after the first "if"

private void \u003CNullableProperty\u003Em__setterMethod([In] object obj0)
{
    if (obj0 == null)
        this.\u003CNullableProperty\u003Ek__BackingField = new int?();
    if (obj0 is int?)
        this.\u003CNullableProperty\u003Ek__BackingField = new int?(Convert.ToInt32(obj0));
    else
        this.\u003CNullableProperty\u003Ek__BackingField = new int?(Convert.ToInt32(obj0));
}
