Error with events and IEnumerable<T>

[Portikus]

Hi I have an Inteface with the following event:

 event EventHandler<IEnumerable<string>> SomeEvent;

When SimpleStubs is now generating the stubs it generates the following:

protected void On_SomeEvent(object sender, IEnumerable args)
{
     global::System.EventHandler<global::System.Collections.Generic.IEnumerable<string>> handler = SomeEvent;
     if (handler != null) { handler(sender, args); }
}
public void SomeEvent_Raise(object sender, IEnumerable args)
{
     On_SomeEvent(sender, args);
}

It generates methods for IEnumerable not for IEnumerable<string> which wont compile.

Hi @Portikus,

Thanks for reporting this issue! Should be a quick fix.

[nehmebilal]

The issue has been resolved in master. I will publish the fix with the next NuGet.

Hi! When can we expect the updated nuget with this fix? This bug is a blocker for me. Thanks!

[nehmebilal]

Sorry for the delay. I will publish the NuGet this week.

Just released 2.3.4 which fixes this issue. Please reopen if you have any problems.

I am still seeing the same issue with the 2.3.4 release. Can someone please verify? Here is my test interface and the generated stub that fails to build:

public interface ISomeInterface
{
    event EventHandler<IEnumerable<string>> SomeEvent;
}

This fails with "Argument 2: cannot convert from 'System.Collections.IEnumerable' to 'System.Collections.Generic.IEnumerable'":

[CompilerGenerated]
public class StubISomeInterface : ISomeInterface
{
    private readonly StubContainer<StubISomeInterface> _stubs = new StubContainer<StubISomeInterface>();

    public event global::System.EventHandler<global::System.Collections.Generic.IEnumerable<string>> SomeEvent;

    protected void On_SomeEvent(object sender, IEnumerable args)
    {
        global::System.EventHandler<global::System.Collections.Generic.IEnumerable<string>> handler = SomeEvent;
        if (handler != null) { handler(sender, args); }
    }

    public void SomeEvent_Raise(object sender, IEnumerable args)
    {
        On_SomeEvent(sender, args);
    }
}

I just created a class library and installed 2.3.4 to it.

I am getting:

    [CompilerGenerated]
    public class StubISomeInterface : ISomeInterface
    {
        private readonly StubContainer<StubISomeInterface> _stubs = new StubContainer<StubISomeInterface>();

        public MockBehavior MockBehavior { get; set; }

        public event global::System.EventHandler<global::System.Collections.Generic.IEnumerable<string>> SomeEvent;

        protected void On_SomeEvent(object sender, global::System.Collections.Generic.IEnumerable<string> args)
        {
            global::System.EventHandler<global::System.Collections.Generic.IEnumerable<string>> handler = SomeEvent;
            if (handler != null) { handler(sender, args); }
        }

        public void SomeEvent_Raise(object sender, global::System.Collections.Generic.IEnumerable<string> args)
        {
            On_SomeEvent(sender, args);
        }

        public StubISomeInterface(MockBehavior mockBehavior = MockBehavior.Loose)
        {
            MockBehavior = mockBehavior;
        }
    }

My bad. It does seem to work. I guess when it updated my nuget reference, there was a lingering nuget .targets file which looked to be referencing the previous version of SimpleStubs. Probably something to do with my recent upgrade to VS 2017, who knows... Thanks!
