Android : "CopyAndConvertResources" task failed unexpectedly (Read-only resources)

"Access to the path ...obj\Debug\res... is denied" when resource files are marked as read-only

I am getting error "CopyAndConvertResources " task failed unexpectedly (Read-only resources)

This problem is particularly noticeable when using TFS because TFS automatically marks all of the resources as read-only.

Error 1 The "CopyAndConvertResources" task failed unexpectedly.
