I am trying to build a .Net application snap, but I am not having much luck. The application was written for .Net Core 3.0.1 (note that .Net 3.1 is also available.) When I try to build the snap using the snapcraft dotnet plugin I get the following error: "The plugin used by part ... does not support snaps using base 'core18'." Googling around it seems that the issue may be that the current dotnet plugin only works with Ubuntu core16 and .Net Core 2.0. These versions are outdated. Please update the dotnet plugin to support later releases of Ubuntu and .Net Core. Thanks!
