WPF Error: IOException - Cannot locate resource

Recently I worked on a WPF application which supports localization using LocBAML tool. I created a sample application, having a very simple UI, consist of a button inside a window. Here I am assuming that most of you are aware on how to generate satellite assemblies. So, quickly coming to the point, when I build my application, build was successful. But when I launched, my application crashed with reason stated as IOException :(

After spending almost an hour, I came to know that it was due to Culture settings. Let's have a look at my code first:

Apart from this above code, I also updated my project file (.csproj) for development language so that my satellite assembly contains the neutral language resources. Following line was added in the project file:
<UICulture>en-US</UICulture>

Apart from this, I did nothing special in my app. After hitting my head on msdn, I got an idea on why culture changes was causing an exception.

Well, no need to get panic. Solution is pretty simple. Let's move ahead and  open your assembly.info.cs file and uncomment below line:
[assembly: NeutralResourcesLanguage("en-US", UltimateResourceFallbackLocation.Satellite)]

After this minor change, we are good to go.
By uncommenting this line, we are telling runtime that culture information needs to be read from satellite assembly.

Hope, this tip will save your time :)
