structuremap

Hi,

I can't figure out how to define the default constructor (when it exists overloads) for a type in StructureMap (version 2.5) by code.

I want to get an instance of a service and the container has to inject a Linq2Sql data context instance into it.

I wrote this in my 'bootstrapper' method :

ForRequestedType<MyDataContext>().TheDefault.Is.OfConcreteType<MyDataContext>();

When I run my app, I got this error :

StructureMap Exception Code:  202
No Default Instance defined for PluginFamily MyNamespace.Data.SqlRepository.MyDataContext, MyNamespace.Data, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null

If I comment out all Linq2Sql generated contructors that I don't need, it works fine.

Update : Oh, and I forgot to say that I would not use the [StructureMap.DefaultConstructor] attribute.
