Why doesn't my Unity DependencyResolver work on shared hosting but works locally?
- by frennky
I'm trying to deploy ASP.NET MVC 3 application wich uses Unity as a IoC container. Application works fine on local server, but when deployed it throws an exception: No parameterless constructor defined for this object. And this is thrown for a controller that should get some repository injected by my Unity DependencyResolver.
I've installed Unity with NuGet so it should be referenced directly, and I've checked that it gets copied to bin folder.
Edit:
Here's the stack trace:
[MissingMethodException: No parameterless constructor defined for this object.]

Anyone have an idea what might be the problem?
