Constructors

MicrosoftDependencyResolver(IServiceCollection?)

Initializes a new instance of the MicrosoftDependencyResolver class with an IServiceCollection.

public MicrosoftDependencyResolver(IServiceCollection? services = null)

Parameters

services IServiceCollection

An instance of IServiceCollection.

MicrosoftDependencyResolver(IServiceProvider)

Initializes a new instance of the MicrosoftDependencyResolver class with a configured service Provider.

public MicrosoftDependencyResolver(IServiceProvider serviceProvider)

Parameters

serviceProvider IServiceProvider

A ready to use service provider.

Properties

ServiceProvider

Gets the internal Microsoft conainer, or build new if this instance was not initialized with one.

protected virtual IServiceProvider? ServiceProvider { get; }

Property Value

IServiceProvider

Methods

Dispose() 

public void Dispose()

Dispose(bool)

Disposes of the instance.

protected virtual void Dispose(bool disposing)

Parameters

disposing bool

Whether or not the instance is disposing.

GetService(Type?, string?)

Gets an instance of the given serviceType. Must return null if the service is not available (must not throw).

public virtual object? GetService(Type? serviceType, string? contract = null)

Parameters

serviceType Type

The object type.

contract string

A optional value which will retrieve only a object registered with the same contract.

Returns

object

The requested object, if found; null otherwise.

GetServices(Type?, string?)

Gets all instances of the given serviceType. Must return an empty collection if the service is not available (must not return null or throw).

public virtual IEnumerable<object> GetServices(Type? serviceType, string? contract = null)

Parameters

serviceType Type

The object type.

contract string

A optional value which will retrieve only objects registered with the same contract.

Returns

IEnumerable<object>

A sequence of instances of the requested serviceType. The sequence should be empty (not null) if no objects of the given type are available.

HasRegistration(Type?, string?)

Check to see if a resolvers has a registration for a type.

public virtual bool HasRegistration(Type? serviceType, string? contract = null)

Parameters

serviceType Type

The type to check for registration.

contract string

A optional contract value which will indicates to only generate the value if this contract is specified.

Returns

bool

Whether there is a registration for the type.

Register(Func<object?>, Type?, string?)

Register a function with the resolver which will generate a object for the specified service type. Optionally a contract can be registered which will indicate that registration will only work with that contract. Most implementations will use a stack based approach to allow for multile items to be registered.

public virtual void Register(Func<object?> factory, Type? serviceType, string? contract = null)

Parameters

factory Func<object>

The factory function which generates our object.

serviceType Type

The type which is used for the registration.

contract string

A optional contract value which will indicates to only generate the value if this contract is specified.

ServiceRegistrationCallback(Type, string?, Action<IDisposable>)

Register a callback to be called when a new service matching the type and contract is registered.

When registered, the callback is also called for each currently matching service. 

public virtual IDisposable ServiceRegistrationCallback(Type serviceType, string? contract, Action<IDisposable> callback)

Parameters

serviceType Type

The type which is used for the registration.

contract string

A optional contract value which will indicates to only generate the value if this contract is specified.

callback Action<IDisposable>

The callback which will be called when the specified service type and contract are registered.

Returns

IDisposable

When disposed removes the callback.

UnregisterAll(Type?, string?)

Unregisters all the values associated with the specified type and contract - or - If the container has already been built, removes the specified contract (scope) entirely, ignoring the serviceType argument.

public virtual void UnregisterAll(Type? serviceType, string? contract = null)

Parameters

serviceType Type

The service type to unregister.

contract string

This parameter is ignored. Service will be removed from all contracts.

UnregisterCurrent(Type?, string?)

Unregisters the current item based on the specified type and contract.

public virtual void UnregisterCurrent(Type? serviceType, string? contract = null)

Parameters

serviceType Type

The service type to unregister.

contract string

The optional contract value, which will only remove the value associated with the contract.

UpdateContainer(IServiceProvider)

Updates this instance with a configured service Provider.

public void UpdateContainer(IServiceProvider serviceProvider)

Parameters

serviceProvider IServiceProvider

A ready to use service provider.
