No Default Instance Defined When Registering With AddAllTypesOf
roend
Code: 202)" when trying to get all instances of a type that was
registered with AddAllTypesOf.
Here's my registry:
public class MyRegistry : Registory
{
}

Do Container.WhatDoIHave() on your container / ObjectFactory. If StructureMap picks up more than 1 concrete type for the plugin type, it will NOT choose either as the default instance for that plugin type.

Code: 202)" when trying to get all instances of a type that was
registered with AddAllTypesOf.
Here's my registry:
public class MyRegistry : Registry
{
public MyRegistry()
{
Scan(config =>
{
config.TheCallingAssembly();
config.AddAllTypesOf<IMyType>().NameBy(t =>
t.FullName);
});
}
}
And here's how I'm trying to access it:
foreach(var myType in ObjectFactory.GetAllInstances<IMyType>()
{
...
The exception happens when trying to iterate on the first item in the
collection.
Here's the relevant stack trace:
[StructureMapException: StructureMap Exception Code: 202
No Default Instance defined for PluginFamily
Rrc.Core.Data.Filters.IActiveUserVisibleDataFilter, Rrc.Core.Data,
Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]
StructureMap.BuildSession.<.ctor>b__0(Type t) +239

StructureMap.BuildSession.CreateInstance(Type pluginType) +16
StructureMap.BuildSession.GetInstance() +48
StructureMap.BuildSession.<GetAllInstances>b__8(Instance x) +63
Am I doing something wrong here?

Sorry for the confusion. I was trying to show a simple example of
what is happening.

You're getting that error because *something* in your container registration that's that interface or a child of that interface has a dependency on IActiveUserVisibleDataFilter and StructureMap doesn't know which one is the *default* for that interface.

The good news, all you need to do right now to make this work is change the code like this:
public class MyParentClassRegistry : Registry
{
public MyParentClassRegistry()
{
// Use this code instead. StructureMap will inject all IMyClass by default
For<IMyParentClass>().Use<MyParentClass>();
// Hide this
//For<IMyParentClass>().Use(c => new MyParentClass(c.GetAllInstances<IMyClass>()));
}
}
You do know that you only need one Registry, right?

For<>.Use<> returns an object that represents the object construction and provides all the chained methods you need to change the name, setup interceptors, or override constructor / setter arguments.
