asp.net-core-2.2

问题 We currently have an ASP.NET Core 2.2 web app that we would like to migrate to 3.1 (as it's newer and contains several enhancements). There are articles on migrating from 2.2 to 3.0 but not 2.2 to 3.1 . Is the preferred migration route to upgrade to 3.0 first then upgrade to 3.1? There seem to be a lot of incompatibilities between 2.2 and the newer 3.0 / 3.1 frameworks. Are there any best practices / general guidelines for upgrading an existing ASP.NET Core 2.2 web app to 3.0 / 3.1 ? 回答1:
