Every time I open my VS solution I get “Projects have recently been added to this solution. Do you want to get them from source control?”
<p>I don't know exactly how, but on a certain moment we ruined our complete visual studio solution. It wouldn't build anymore, nor clean, nor find any reference.</p>

<p>Afters hours of searching and trying to fix everything we got to the point that everything was building and running again.</p>

<p>However.. every time we open our solution we will get the message “Projects have recently been added to this solution. Do you want to get them from source control?”. </p>

<p>This is probably cause by trying to fix one thing and breaking something else.</p>

<p>How do we get rid of this message?</p>
