Because some .csproj projects don't have <TargetFrameworks> net5.0 </TargetFrameworks>

[choss21]

Hi all
Currently I use serenity as a Submodule, in an application with Docker

but the projects:Serenity.Net.Core, Serenity.Net.Data, Serenity.Net.Entity, and Serenity.Net.Services they do not have tag "net5.0" and docker build failed (error: " invalid framework identifier'' "),

I had to add " net5.0 " for it to work properly

I would like to know your opinion on this issue

regards
