Description umbr0no 2011-08-14 07:12:06 UTC
Created attachment 125 [details]


I try to compile Umbraco 5 with the latest mono 2.11. 

I Checked out mono from git master to pass the MVC compiler error described here : https://bugzilla.novell.com/show_bug.cgi?id=673604

I isolated a first problem, steps to reproduce :

Create mono 2.11 project, reference Autofac (included in attachment)

public void Test<T>()	{

var builder = new ContainerBuilder(); 

IRegistrationBuilder<T, ConcreteReflectionActivatorData, SingleRegistrationStyle> x1 = builder.RegisterType<T>();

IRegistrationBuilder<T, IConcreteActivatorData, SingleRegistrationStyle> x2 = builder.RegisterType<T>();


This will throw an exception like

/home/mono/Projects/Problem/Problem/Main.cs(103,103): Error CS0266: Cannot implicitly convert type `Autofac.Builder.IRegistrationBuilder<T,Autofac.Builder.ConcreteReflectionActivatorData,Autofac.Builder.SingleRegistrationStyle>' to `Autofac.Builder.IRegistrationBuilder<T,Autofac.Builder.IConcreteActivatorData,Autofac.Builder.SingleRegistrationStyle>'. An explicit conversion exists (are you missing a cast?) (CS0266) (Problem)

On MS .NET 4 this compiles without a problem.
