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 seeing the same error. In my case, I had a typo in the implementation name, so the interface and implementation names did not match.

public class FooTypo : IFoo

Where I should have had:

public class Foo : IFoo
