UDP Socket with ECS

[limber olive]

I would like to use a managed class UdpClient (https://learn.microsoft.com/en-us/dotnet/api/system.net.sockets.udpclient) in my ECS code.
When I try to use SystemAPI.GetSingleton or GetSingletonEntity I get The type 'xxx' must be a non-nullable value type, along with all fields at any level of nesting, in order to use it as parameter 'T' in the generic type or method 'SystemAPI.GetSingleton<T>()'

There is SystemAPI.ManagedAPI for class components

btw

there is Unity.Tranport

which is part of DOTS
