Hi
I have created a additional project to try something.

I wanted to add a language EN-US to the default EN one and I got this error message.

I deleted this project.

But the problem I got the same message when trying to open my main project.

I get always the same error even after putting a back up of my DB project. :

An item with the same key has already been added.

Any Idea about what could be the problem.

Hi,
I solved this : it is in the ResourceConfig

<add culture="en-US" uiCulture="en" key="english-en-us" />
<add culture="fr-CA" uiCulture="fr-CA" key="french (canada)-fr-ca" />
<add culture="fr" uiCulture="fr" key="french-fr" />
<add culture="en" uiCulture="en" key="english-en" />

I deleted the entry for culture="en" and it fixed the problem.

the error is telling that culture="en-US" and culture="en" use the same Key (here they are different:) ) but I don't know where this could come from.
