asp.net core 2.0 unable to delete PreCompiledViews.dll

Question

I have an asp.net core 2.0 web application.

When I publish it to a web server (using a UNC path), the [AppName].PrecompiledViews.dll becomes locked and I'm unable to delete it (and therefore can't re-publish the app).

I've tried manually deleting the file(s) - everything deletes fine, except for this one dll... and I don't have permission to go and restart the IIS worker process to free the lock, so I'm at a loss as to what to do... waiting for the app to recycle is my current best plan.

Any suggestions are welcome.

This work for me deploying from appveyor to an azure server:

You can configure the appOffline rule in the publishing profile (.pubxml). Add the EnableMSDeployAppOffline element to the PropertyGroup like this:

<PropertyGroup>
  <EnableMSDeployAppOffline>true</EnableMSDeployAppOffline>
</PropertyGroup>
