Hello Ahmet,
In general, the purpose of the ObjectDataSource component is to provide data to the report in a declarative manner. The ObjectDataSource.DataSource should be the assembly qualified name or Type of the data access layer (class), where the reporting engine will use System.Reflection to create the instance of the class (by using its default constructor) and to execute its method specified by the ObjectDataSource.DataMember.
Having the above into account, the data access layer must have a default parameterless constructor in order to be instantiated.
In case it is a data model created via Entity Framework, please consider switching to the EntityDataSource component.

Dependancy Injection like with Autofac kinda throws a monkey wrench into this.

Hi Greg,
The Reporting engine uses System.Reflection to invoke the data retrieving functionality described in the ObjectDataSource. The latter accepts parameters: Using Parameters with the ObjectDataSource Component and in some cases, it may be possible to use dependency injection. For example, if the injected values are primitive and can be passed as Report Parameter values. Note that if the DataMember is not provided, the DataSource constructor will be used and the parameters will be passed to this constructor.
