Invalid resx file. Failed to load type System.Collections.Generic.List

Question

I have a property in my usercontrol, but when I add usercontrol to my foem and want to run, I got this error on Visual Studio 2010, but this error does not appear on VS 2008: "Invalid Resx file. Failed to load the System.Collections type .Generic.List .... "

[Serializable] public class ActionPoint { public string CarInfo; public string RightStationName; public string RightStationInfo; public string LeftStationName; public string LeftStationInfo; public ActionPoint() { } } public class Line : UserControl { public List<ActionPoint> Stations { get { return Stations; } set { Stations = value; } } } 

Answer 1

If you register your resx file, do you have a data section?

I have no idea what exactly happened, but what worked for me was to delete two sections of data where binary (serialized) data was stored:

Answer 2

Have you tried creating a new UserControl and copying the code to a * .cs file? Your resx file may be corrupt.
Update: Your question seems similar to this one .
