Yesterday I've implemented the code:

CustomerProductManager productsManager = container.Resolve<CustomerProductManager>();

It was compilable and working.

Today (probably I've modified something I am constantly getting the error:

The non-generic method 'Microsoft.Practices.Unity.IUnityContainer.Resolve(System.Type, string, params Microsoft.Practices.Unity.ResolverOverride[])' cannot be used with type arguments

My collegue has the same source code and doesn't have same error. Why? How to resolve the problem?

P.S.

line "using Microsoft.Practices.Unity;" is present in usings section.

I've tried to replace generic version with non-generic one:

CustomerProductManager productsManager = (CustomerProductManager)container.Resolve(typeof(CustomerProductManager));

And got another error:

No overload for method 'Resolve' takes '1' arguments

It seems like one of the assemblies is not referenced.. but which one? I have 2 of them referenced: 1. Microsoft.Practices.Unity.dll 2. Microsoft.Practices.ServiceLocation.dll

P.P.S. I've saw similar problem http://unity.codeplex.com/WorkItem/View.aspx?WorkItemId=8205 but it is resolved as "not a bug"

Any thought will be helpful
