Create a project template for message assemblies #541
Description
Describe the feature.
The NServiceBus.MessageInterfaces provides a common, unchanging source for the IEvent, ICommand, and IMessage interfaces necessary for creating message assemblies. Using this package, message assemblies can be created that can even be shared between legacy NServiceBus 8 endpoints on .NET Framework and newer NServiceBus endpoints on .NET 8 or later.
But to do this, the message assembly must target netstandard2.0. And with that target framework, you can't use record types (which are very useful for quickly creating immutable message types) without additional settings.
An "NServiceBus Message Assembly" project template could combine all these factors in one easy-to-use package.
