Okay, one of the most annoying thing that happened to me was my value object/model class was getting this strange k__BackingField appended to the fields. This is how the class looked like
[Serializable]
public class UserVO
{
[DataMember]
public long ID
{
get;
set;
}
[DataMember]
public string Username
{
get;
set;
}
[DataMember]
public string Password
{
get;
set;
}
}
I had to use a WCF proxy generator to generate a proxy class that will access this classes parent SOAP service. However in the proxy, the fields are accessed in this manner:
var user = _userDataSource.GetCurrentUser(username, password);
string userName = user.Usernamek__BackingField;
Now that shit ain't right and I felt like I dropped the SOAP on this one.
After some digging, it turns out that the [Serializable] attribute/decorator of the class was causing this issue. Remove it and it will be solved.
Hope this helps.
