Trouble with Slot Setting for Azure App Services : <p>I need to understand Slot Application Settings better for Azure App Services. When they apply and how to use them correctly.</p>

<p>I have 2 App Services set up each running 2 slots as below.</p>

<ol>
<li>Site 1 with slot - building-staging</li>
<li><p>Site 1 with slot - staging</p></li>
<li><p>Site 2 with slot - building-production</p></li>
<li>Site 2 with slot - production</li>
</ol>

<p>So for each site, I'd like to be able to put an invalid connectionstring for the build slot in the Application Settings blade so that the site can't be accessed and will just give you basically an error page on the azuerwebsites.net url for that slot.</p>

<p>In my production slot of each I then want to put the correct connectionstring so that once swapped they will work.</p>

<p>I can not get this to work reliably, the settings don't apply when I swap. Should I be marking the connection strings on the production slot as slot settings? Should the original one on the build slot be a slot settings? Do I need some kind of nuget package installed I'm not aware of.</p>

<p>Please help</p>
