I install Umbraco downloading the zip and installing the web as a web folder not a web application. Its easier for me as i do a lot of small projects. Also have a little bit of code on the App_Code folder. So i dont need to build the site, when i want to update a site i upload by ftp the modified files.

Now i have created a repository using Azure devops. I would like when i make a commit to have a pipeline to copy the modified files (not all the files) to the azure web app. Some variables change on the web.config, mostly some app settings and the connection string but i guess i can handle it on the azure web app to override those settings.

As i have seen the pipelines build the site (MSBuild) and as it is not a solution or web project it fails. How can achieve this?
