pkgobj\Debug\Package_Manifest.xml is read-only?

Question

When I package a Sharepoint 2010 project in Visual Studio 2010, I occasionally get the following error message:

Access to the path 'C:\path-to-my-project\pkgobj\Debug\Package_Manifest.xml' is denied.

I checked the file, and it seems to be read-only. Clearing the read-only flag helps, but eventually the problem reoccurs. What's causing it and how can I fix it for good?

Answer 1

You need to run the visual studio as Administrator

Answer 2

I am able to get around the problem by checking-out the AppManifest.xml file in the project, thereby removing the read-only. For some reason the publish process copies this file over and keeps the read-only flag, causing the error.

Answer 3

The UAC requires that you run Visual Studio as a system administrator.

To develop SharePoint solutions, you must have sufficient permissions to run and debug SharePoint solutions. Before you can test a SharePoint solution, take the following steps to ensure that you have the necessary permissions:

• Add your user account as an Administrator on the system.
• Add your user account as a Farm Administrator for the SharePoint server.
• In SharePoint Central Administration, click the Manage the farm administrators group link.
