The [NeutralResourceLanguage] attribute is missing on the entry assembly

Question

I'm trying to submit an app to the windows phone 7 marketplace and have never encountered this error when validating my .xap package. App Hub just remodeled and became back online roughly an hour ago. Does anyone know how I can fix this?

Answer 1

I'm getting the same thing.. Maybe their new update they just made doesn't work?

Found it... Update Assembly.cs with this:

using System.Resources;  // Add this to the top..

[assembly: NeutralResourcesLanguage("en-US", UltimateResourceFallbackLocation.Satellite)]

This worked for me.. Cheers..

Note per Blakomen:

If you are submitting an application for worldwide publishing, you should use NeutralResourcesLanguage("en"), not just "en-US" or it won't show up in the marketplace if you're trying to publish to UK marketplace, for example (it will for some reason come up for Korea and Japan though)

This is a new requirement of the app hub (ready for Mango) where all applications must now have a neutral resource language specified. This is to allow the correct support for the new langauges that Mango supports. – Ratfink

Just a note that if you are submitting an application for worldwide publishing, you should use NeutralResourcesLanguage("en"), not just "en-US" or it won't show up in the marketplace if you're trying to publish to UK marketplace, for example (it will for some reason come up for Korea and Japan though) – Schnozzle

Answer 2

• In Solution Explorer, right-click the project name, and click Properties.
• Under the Application tab, click the Assembly Information button.
• In the Neutral Language list, select the default culture.

This worked for me. My application didn't have a default language specified, so in the update I've set it to English. Anyway now I'm stuck at the "No Keywords or Description (Missing)" bug, good luck.

Great answer! Both your and Devo's answers worked for me. I prefer your way but already gave the check mark away. Sorry! Thanks for the info though – Laudable

Answer 3

I have the same problem. After adding the NeutralResourcesLanguage("en-US"), I got another error from app hub saying that I can't change previously submitted language. Then I used NeutralResourcesLanguage(null) followed by a weird unexpected error message from app hub recommending me that now might be an excellent time to go out for a walk :) Seriously!!!

Hah interesting :) I had the same problem then I checked details on my application and it said English(international) so I added [assembly: NeutralResourcesLanguageAttribute("en")] instead and it worked. Good luck! – Laudable

Answer 4

Open the AssemblyInfo.cs from your project and add the following at the top "using System.Resources;"

There is a new requirement of the app hub (ready for Mango) where all applications must now have a neutral resource language specified.

                        **OR ALTERNATIVELY TRY THIS:**

1. Right click your project and select "properties"
2. Click on the Assembly Info button

3. Select Neutral language and choose a language of your choice. I work with English so i just choose English and you are good to go.
