Class EnumerableResolutionAdapter<T>

Namespace

Remarks

The BoDi DI container which is included in Reqnroll/SpecFlow does not fully support the functionality of Microsoft's DI standard. Notably, it cannot natively resolve an IEnumerable<T>, where type T is a service type which may have multiple implementations added to/registered with the container. BoDi does have conceptually identical functionality, in its ResolveAll<T>() function.

The purpose of this type is to provide a mechanism by which BoDi may resolve enumerables of service types. This class wraps an instance of IObjectContainer and - in its GetEnumerator() method - redirects to the ResolveAll<T>() method.

The limitation of this type (as a workaround) is that this type must be added to the container manually for each IEnumerable<T> type which could be resolved from the container.
