public bool TryGetExports (System.ComponentModel.Composition.Primitives.ImportDefinition definition, System.ComponentModel.Composition.Hosting.AtomicComposition? atomicComposition, out System.Collections.Generic.IEnumerable<System.ComponentModel.Composition.Primitives.Export>? exports);
public bool TryGetExports (System.ComponentModel.Composition.Primitives.ImportDefinition definition, System.ComponentModel.Composition.Hosting.AtomicComposition atomicComposition, out System.Collections.Generic.IEnumerable<System.ComponentModel.Composition.Primitives.Export> exports);
member this.TryGetExports : System.ComponentModel.Composition.Primitives.ImportDefinition * System.ComponentModel.Composition.Hosting.AtomicComposition * seq -> bool
