 <p>Application resource files cannot be deployed via a feature unless you execute some code and start a SharePoint timer job that copies the files to the App_GlobalResources folder on each Web front-end server.</p> <p>You should instead let the SharePoint solutions framework deploy the .RESX files to the App_GlobalResources folder on each server. You can specify application resource files as follows in the manifest.xml file of your WSP solution package:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;Solution SolutionId="{185E973C-3A10-4e2a-9E0F-DC14414551F9}" xmlns="http://schemas.microsoft.com/sharepoint/" DeploymentServerType="WebFrontEnd"&gt; &lt;ApplicationResourceFiles&gt; &lt;ApplicationResourceFile Location="yourappname.resx"/&gt; &lt;ApplicationResourceFile Location="yourappname.en-US.resx"/&gt; &lt;/ApplicationResourceFiles&gt; ... &lt;/Solution&gt; </code></pre> <p>When you deploy the WSP solution package using STSADM or Central Administration, the SharePoint solutions framework will start a timer job that deploys these files to the App_GlobalResources folder of all the Web applications you decided to deploy the solution to. </p>
