TravelGate.Extensions.DependencyInjection.AutoWire 2.0.0

AutoWire

Library to auto register dependencies and to auto bind option classes for Microsoft.Extensions.DependencyInjection

Getting Started

Just call AutoWire on your service collection, like:

serviceCollection.AutoWire(config);

Where config is of type IConfiguration.

Usually that's all you need. AutoWire will auto register types as services and options if the following applies:

For services

• They are classes, including generics with open type (SomeType<>).
• They belong to the entry assembly as obtained by Assembly.GetEntryAsembly().
• They are not marked with or inherit [IgnoreAutoWire] attribute.
• They are not abstract or nested.
• They don't end with "Options".

For options

• They are classes.
• They have a parameter-less constructor.
• Their name match a section from the provided IConfiguration object.

Additional features

Use IncludePrefixed option

Using this option only classes under to the IEnumerable<string> namespace prefixes are added.

var sc = new ServiceCollection();
sc.AutoWire(config, options => options.IncludePrefixed = new[] { typeof(SomeClass).Namespace });

For example, assuming that someClass belongs to ProjectName.Folder, all classes located in the same namespace will be registered.

Use RegisterByAttribute option

var sc = new ServiceCollection();
sc.AutoWire(config, options => options.RegisterByAttribute = true);

Using this option only classes that are marked with or inherit [AutoWire] are registered. For example:

[AutoWire]
public class SomeClass {}

NOTE: if both IncludePrefixed and RegisterByAttribute, they are both applied and in this order.

Ignoring classes

If you wish to ignore a class or derived classes from a base class or interface, mark the class, base class or interface with [IgnoreAutoWire], for example:

[IgnoreAutoWire]
public class SomeClass {}
