Visual Studio : ReplacableToken_ApplicationServices on transform

Using VS 2015 and doing a transform on my web.config.

My connection string is something like:

connectionString="data source=.\SQLEXPRESS;Integrated Security ..."

but what appears in the transformed file is:

connectionString="$(ReplacableToken_ApplicationServices-Web.config Connection String_0) ..."

WTF?

Much conversation with Mr. Google and eventually the solution is:

<AutoParameterizationWebConfigConnectionStrings>False</AutoParameterizationWebConfigConnectionStrings>

You need to add this to the appropriate .pubxml file under Properties\PublishProfiles

Enjoy!
