v0.2.0

Added

• Added scopes support (IServiceScope, IServiceScopeFactory).
• Added CreateInstance() extensions to IServiceProvider.
• Added GetRequiredService() extensions to IServiceProvider.
• Added Contains() and Remove() overloads to IServiceContainer.

Changed

• Changed namespace to UnityFx.DependencyInjection.
• Changed IServiceProvider.GetService() implementation to return null on resolve errors (instead of throwing an exception).
• Changed ServiceProvider to have internal constructor. ServiceProvider instanced should be created with BuildServiceProvider extension of IServiceCollection.
• Changed resolve validation to run on ServiceProvider construction (not on resolve).

Removed

• Removed all assembly-specific exceptions. InvalidOperationException is thrown on resolve errors instead.
