Could not find any resources appropriate for the specified culture or the neutral culture

Question

I have two ASP.NET Web projects (ProjectA and ProjectB). When class in ProjectA is instantiating a class of ProjectB which uses a resource file Blah.resx, I get this error:

Answer 1

In my case, the issue caused by defining class the wrong way:

namespace MyBuggyWorld
{
    public class BackendObject //This hack broke the VS 2017 winform designer and resources linker!
    {
        public TcpClient ActiveClient { get; set; }
        public BackgroundWorker ActiveWorker { get; set; }
    }
    public partial class FormMain : Form
    {
    }
}

After Reallocating BackendObject to the end (better to separate file), doing project clean + rebuild resolved the issue.
