A new project `DigitalData.MessagingService.Client` has been added, targeting `net462` and `net8.0`. The project includes metadata for packaging and distribution, such as `PackageId`, `Authors`, `Version`, and more.
The solution file `DigitalData.MessagingService.sln` has been updated to include the new project, with build configurations for `Debug|Any CPU` and `Release|Any CPU`. The project is nested under the `infrastructure` folder in the solution structure.
Added three new projects ("presentation", "core", and
"infrastructure") to the solution file with unique GUIDs.
Updated the `GlobalSection(NestedProjects)` to reflect the
new project structure, nesting the new projects under the
parent project with GUID `{02EA681E-C7D8-13C7-8484-4AC65E1B71E8}`.
Removed outdated nested project mappings and replaced them
with mappings for the new projects. Updated the solution
file to ensure proper integration of the new projects.
