I've got a 'Build Solution' step for a ASP.NET project in Azure DevOps and it's failing because it's trying to use an old version of a package. In my code it's only referenced in the packages.config and I've changed that entry to use version 1.0.7, but in Azure DevOps it's still trying to find 1.0.2 but fails to find it. Any ideas why it's trying to use the wrong package version or how to force it to get the new one? My project in visual studio has no references to the old version.
