1) Make sure you transform works. Test it here.

2) Ensure in your VS project that you are including the transform file, Web.Preview.config, and copying to output dir.

3) Disable the config transform during the build, you just need to add argument /p:TransformWebConfigEnabled=False in MSBuild Arguments section of your Build task. You also need to add /p:AutoParameterizationWebConfigConnectionStrings=False if you want to update the connection string during the release. This will use the Web.Preview.config to "transform" the web.config.

4) Double check that in your release for the IIS Web App Deploy task under File Transforms & Variable Substitution Options you have XML transformation checked.
