Breaking Change

[AlexArchive]

Whilst following this tutorial I discovered what I believe to be a breaking change.

Using the latest version of Moq (which as of this time of writing is 4.2.1408.511) the following code throws an (esoteric) exception:

[TestMethod] 
public void Create() 
{ 
    var mockSet = new Mock<DbSet<Blog>>(); 
    var mockContext = new Mock<BloggingContext>(); 
    mockContext.Setup(m => m.Blogs).Returns(mockSet.Object);
    ...

The exception:

Castle.DynamicProxy.Generators.GeneratorException : Type System.Data.Entity.Internal.Linq.IInternalQueryAdapter is not visible to DynamicProxy. Can not create proxy for types that are not accessible. Make the type public, or internal and mark your assembly with [assembly: InternalsVisibleTo(InternalsVisible.ToDynamicProxyGenAssembly2)] attribute.
at Castle.DynamicProxy.DefaultProxyBuilder.AssertValidType(Type target)
at Castle.DynamicProxy.DefaultProxyBuilder.AssertValidTypes(IEnumerable1 targetTypes) at Castle.DynamicProxy.DefaultProxyBuilder.CreateClassProxyType(Type classToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options) at Castle.DynamicProxy.ProxyGenerator.CreateClassProxy(Type classToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options, Object[] constructorArguments, IInterceptor[] interceptors) at Moq.Proxy.CastleProxyFactory.CreateProxy(Type mockType, ICallInterceptor interceptor, Type[] interfaces, Object[] arguments) at Moq.Mock1.b__0()
at Moq.Mock1.OnGetObject() at Moq.Mock1.get_Object()
at Blog.UnitTest.Test.Create() in Test.cs: line 19

However, using Moq 4.1.1309.1617 (which I guessed to be the version the author used based on the release date of EF6) the aforementioned code works as expected!

Please note that this occurs with both EF 6 and EF 6.1 in my experience and that I only tested that Moq 4.1.1309.1617 works - the breaking change could have been introduced after that for all I know.

Looks like this might have just been solved moments later here. What a stunning coincidence 😃

Just install the latest & greatest. Thanks! I'l pull the previous release
