I am working on a sample message handler service using NServiceBus in a .NET 4.5 project. It works fine as long as DefaultBuilder is used. To configure the container for other services with Autofac as soon as reference to Autofac is added and DefaultBuilder is changed to AutofacBuilder, I get exception as shown below. reference to NServiceBus.ObjectBuilder.Autofac.dll is already in the project.
Exception when starting endpoint, error has been logged. Reason: Could not load file or assembly 'Autofac, Version=2.6.1.841, Culture=neutral, PublicKeyToken=17863af14b0044da' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
WRN: Comparing the assembly name resulted in the mismatch: Major Version
ERR: Failed to complete setup of assembly (hr = 0x80131040). Probing terminated.
What am I doing wrong? I have tried Nuget, manual reference, changing target framework to 4.0.
EDIT
After adding the binding redirects, the error message changes to
Method not found: 'Autofac.Builder.IRegistrationBuilder`3<!0,!1,!2>
Autofac.Builder.IRegistrationBuilder`3.PropertiesAutowired(Autofac.PropertyWiringFlags)'.
