Thanks for your feedback.
Just to be sure, I created a simple project (NuGetTest), containing some localized resources and a dummy class.
Then I let nuget generate the spec file, and modified it according to the information from this thread, to include satellite assemblies:
<releaseNotes>Simple test to try to include localized resource assemblies.</releaseNotes>
<tags>test sample satellite assembly resource localized</tags>
(I even tried omitting the specific file name, using * wildcard instead).
Finally, I generate the package. Despite the inclusion, the resource files (with proper target) are not included (I verified both using NuGet Package Explorer and browsing the package as a zip file).
I am invoking spec/pack commands directly inside the VS powershell, the NuGet version is 2.1.31022.9038.
I am probably doing a silly mistake, but I cannot figure out which...
