Introduce conditional compilation directives in the IRepository interface to support .NET Framework. Update method signatures to conditionally include the `public` access modifier for compatibility across frameworks. Adjust the Entity method to remove the `public` modifier, enhancing flexibility while maintaining existing functionality.
- Introduced GetAll() and GetAllAsync() to provide full entity retrieval options.
- Updated obsolete warnings:
- Read() now marked with "Use CreateAsync, UpdateAsync or DeleteAsync".
- ReadOnly() points to IRepository<TEntity>.Where.
- Removed old Get() method in favor of new retrieval methods.
- Updated `IRepository<TEntity>.Where()` to accept an `Expression<Func<TEntity, bool>>` for filtering.
- Added `where TEntity : IEntity` constraint to `IRepository.Entity<TEntity>()` method.
- No functional logic changes, only interface refactoring for stronger typing and query support.
- Replaced `Read()` with `Where()` and `ReadOnly()` with `Get()` in `IRepository<TEntity>`
- Marked `Read()` and `ReadOnly()` as `[Obsolete]` with guidance for the new methods
- Added non-generic `IRepository` interface with `Entity<TEntity>()` method
Changed UpdateAsync and DeleteAsync to accept Func<IQueryable<TEntity>, IQueryable<TEntity>> instead of IQueryable<TEntity>
Improved flexibility by allowing callers to compose queries dynamically
Updated overloads to wrap expressions with q => q.Where(expression) for compatibility
