I have the same problem!
What do you mean by ignoring it? If I click on the OK button, then it won't be added to my form. What should I do?

it's buggy designer, you may add some panel, and the map control manualy

I closed visual studio and opened it again and the problem was solved!
But now I have another problem!

What's wrong with this piece of code?
private void Form1_Load(object sender, EventArgs e)
        // Initialize map:

        gmap.MapProvider = GMap.NET.MapProviders.YahooMapProvider.Instance;
        GMap.NET.GMaps.Instance.Mode = GMap.NET.AccessMode.ServerOnly;
        gmap.Position = new PointLatLng(32.641218, 51.67576);
while gmap is my instance of GMapControl component.

When I run the program, it gives this error:
A first chance exception of type 'System.TypeInitializationException' occurred in

Additional information: The type initializer for 'GMap.NET.WindowsForms.GMapControl' threw an exception.

And it refers to this line in Designer.cs code:
this.gmap = new GMap.NET.WindowsForms.GMapControl();

Would you please help me?

I enabled first chance exceptions. Now it gives this error:
A first chance exception of type 'System.BadImageFormatException' occurred in GMap.NET.Core.dll

Additional information: Could not load file or assembly 'System.Data.SQLite, Version=, Culture=neutral, PublicKeyToken=db937bc2d44ff139' or one of its dependencies. An attempt was made to load a program with an incorrect format.

what dose it mean? I've added System.Data,SQLite.dll into the project's references and add using System.Data.SQLite, expression to my code too. And I copy System.Data.SQLite.dll from the source code directory which I was worked it before without any problem.

So what's the problem with my program?!

remove System.Data,SQLite.dll from the references
