Project Server 2016: The namespace Resources already contains a definition for PWA

This issue occurs in case you have multiple PWA resources files for the same language at the App_GlobalResources folder of the web application that holds the PWA instance.

Solution

In Project Server 2016/2013, to solve "The namespace Resources already contains a definition for PWA", you should do the following:

  1. log in to the WFE server within your SharePoint farm.
  2. Open IIS > Expand Sites.
  3. Right-click on the Web Application that holds the PWA instance, and selects Explore.

Explore Web Application in IIS
4. Double Click on "App_GlobalResources" to open it.

Open App_GlobalResources folder-min
5. Sort by Name, and search for PWA.
6. Make sure that you have only one resource file for each language pack you have installed.
7. In my case, I had noticed that I have two PWA resource files for the English language with a different name.

8. I have deleted the duplicate one, then go back to browse the PWA instance.
9. Great, the PWA Instance is working now properly without getting this error "The namespace Resources already contains a definition for PWA".
