StructureMap Exception Code: 202 No Default Instance defined for PluginFamily

Question

I am new to StructureMap. I have downloaded and am using version 2.6.1.0. I keep getting the below error:

StructureMap Exception Code: 202 No Def

Answer 1

I was getting the same error message, but for a different reason. I had a class Foo that defined two constructors like so:

public class Foo : IFoo
{
    private Bar _bar;

    public Foo()
    {
       _bar = new Bar();
    }

    public Foo(Bar bar)
    {
        _bar = bar;
    }
}

and my StructureMap configuration was like so:

For.Use();

I kept getting an error message like

202 No Default Instance defined for Bar

The problem was that StructureMap was trying to construct a Foo using the constructor that takes a parameter, instead of using the parameterless default constructor. I solved it using the answer in How to define a default constructor by code using StructureMap? like so:

For.Use(() => new Foo());
