DotNetty .net7.0 published Aot ok, but error to run examples/Echo.Server

[wenchao-cui]

(1) I changed all the dotnetty .csproj files changed TargetFrameworks to net7.0 added PublishAot

<PropertyGroup> <OutputType>Exe</OutputType> <TargetFrameworks>net7.0</TargetFrameworks> <GenerateAssemblyInfo>false</GenerateAssemblyInfo> <Configurations>Debug;Release;Package</Configurations> <Platforms>AnyCPU</Platforms> <PublishAot>true</PublishAot> </PropertyGroup>

(2) Compiled examples/Echo.Server as debug / release version, run Echo.Server.exe, everything was OK OK

appsettings.json { "ssl": "false", "port": "28007", "libuv": "false" }

(3) Published the project win-x64 OK.
But there was error to run the Echo.Server.exe

To make it AOT compatible you need to make it trim compatible. To make it support trimming you need to annotate the library with DynamicallyAccessedMembers / DynamicDependency etc. Since there is no active development in dotnetty and there is no one to merge community PRs, then do not expect this to be solved.
