I developed a single-project Net Core site under Visual Studio for Mac some time ago, and published under Azure as a Web App.
Since, the site has become a multi-project site. If I attempt to publish now to Azure, the publication works Okay, but when I run the site, I get a message "...type XXX could not be found in assembly YYY...", indicative of the old one-project structure.
However, if I publish the same project to an entirely new Web App on Azure, it works fine.
So I assume publishing to the old Azure web app is failing to completely delete the old DLLs.
How can I flush the old web app site so I can publish to it as if it were the first time?
