Hi,

After hours of dubuging, I finally found the workaround.

1.In Solution Explorer, right-click the project name, and then click Unload Project to close the project while leaving the project icon visible.

2.In Solution Explorer, right-click the project name, and then click Edit. The project file opens in the Visual Studio XML Editor.

3. In the project file, add one line under the node of "PropertyGroup" like this:

<PropertyGroup>
  <UICulture>de-De</UICulture>
  ........
  .......
........

That's the cultureinfo which you will be set in the NeutralResourcesLanguageAttribute.

Save the project file and then reload the project and then build the project again, finally you will get the trick.
