WhatDoIHave

WhatDoIHave is an extension method for the IExportLocator inteface that generates configuration information as a string for the container or injection scope it's executed on.

Container example

Below is an example of configuring a container and then printing the output to the console

DependencyInjectionContainer container = new DependencyInjectionContainer();

container.Configure(c =>
			{
				c.Export<BasicService>().As<IBasicService>();
				c.Export<ConstructorImportService>().AndSingleton();
			});

string whatDoIHaveStr = container.WhatDoIHave(true);

Console.Write(whatDoIHaveStr);

Output

Child Scope Example

This example shows how to configure a child scope and then print out the child and parent content

DependencyInjectionContainer container = new DependencyInjectionContainer();

container.Configure(c => c.Export<ConstructorImportService>().AndSingleton());

using (IInjectionScope child = container.CreateChildScope(c => c.Export<BasicService>().As<IBasicService>()))
{
   string whatDoIHave = child.WhatDoIHave(true);

   Console.Write(whatDoIHave);
}

Produces output

Filter Example

Below is an example of configuring a container and a child scope, then printing out all the information on IBasicService exports

DependencyInjectionContainer container = new DependencyInjectionContainer();

container.Configure(c => c.Export<ConstructorImportService>().AndSingleton());

using (IInjectionScope child = container.CreateChildScope(c => c.Export<BasicService>().As<IBasicService>()))
{
   string whatDoIHave = child.WhatDoIHave(includeParent: true, 
                                          consider: ExportsThat.AreExportedAs<IBasicService>());

   Console.Write(whatDoIHave);
}

Produces output
