Updated `DigitalData.UserManager.Domain.csproj` to target .NET Framework 4.6.2 alongside .NET 7.0, 8.0, and 9.0. Corrected `PackageTags` from "user maanger" to "user manager" and added property groups for implicit usings and language versions.
Introduced nullable reference types in entity classes (`BaseEntity`, `ClientUser`, `Group`, `User`, etc.) for enhanced type safety. Updated properties in the `User` and `UserRep` classes to use the new nullable syntax, ensuring consistency across the codebase.
These changes improve compatibility with newer C# features and maintain support for multiple frameworks.
- Updated package references to newer versions for `DigitalData.Auth.Client`, `DigitalData.Core.API`, `DigitalData.Core.Abstractions`, `DigitalData.Core.Application`, and `DigitalData.EmailProfilerDispatcher.Abstraction`.
- Changed `UserManager.Domain` package version from `3.0.2` to `3.1.0` and updated assembly and file versions.
- Removed `IUnique<int>` interface implementation from `BaseEntity`, `ClientUser`, `Module`, and `ModuleOfUser`.
- Added data annotations to the `User` class for various properties that were previously commented out.
- Updated `Microsoft.EntityFrameworkCore` package references in the `Infrastructure` project for `net7.0` and `net9.0`.
- Modified solution configuration to change a project's build configuration from Debug to Release.
