Hi, I am currently working on a library in .Net and I planned to make the strings that are used within the library into culture specific resource files. I made Resources.resx, Resources.en-US.resx and Resources.ja-JP.resx file. I also deleted the Resources.designer.cs file autogenerated by visual studio 2008. I am loading Resources through my custom ResourceManager object [using GetString method]. The problem that I am facing is that when I compile the library within visual studio and set the culture from the calling application, everything is working fine.

But if I manually go to the directory and change a string for a culture and regenerate the satellite assembly with resgen and al.exe, the string displayed, falls back to the invariant culture. I have attached the ildasm view of both the dlls

Can anyone help me as to why these two files are different and what is going on here? Why would the same Japanese resource file work when generated from within visual studio and not when generated using tools.
