Error in binding resource string with a view in WPF

Question

I am trying to bind a static string defined in the Resources.resx called title. When I run the application I get the following error below.

Upon investigating the error on this site, I found that the generated Resources class is marked internal and WPF is trying to resolve the resource from another assembly, so it won't succeed until your resources are marked as public. The same, I have a single project which contains my views and resources defined.

I don’t need any friend assembly. I believe the internal class can be accessed within the same assembly. I found a similar post by a fellow user in which he suggested to use ResXFileCodeGenerator. What is your say on this?

It seems that you need to use the PublicResXFileCodeGenerator generator.

Try right clicking on the resource file in the Visual Studio Solution Explorer and selecting the Properties option and then setting the Custom Tool property to PublicResXFileCodeGenerator. You can also set the Access Modifier property to Public in the resources designer window in Visual Studio.
