Extension method issue

[kentar...@gmail.com]

Hi Nate, I found a issue using both extension method and ninject
together,

It initially threw a Warn like this one:
The predefined type
'System.Runtime.CompilerServices.ExtensionAttribute' is defined in
multiple assemblies in the global alias; using definition from 'c:\xxx
\Ninject-1.0-release-net-2.0\Ninject.Core.dll'

And then The compiler Threw an error saying:
Missing compiler required member
'System.Runtime.CompilerServices.ExtensionAttribute..ctor'

Seems that a temporary solution is to remove and readd the ninject v.
1.0.0.82 dll
But if I was in you i will investigate a bit on this issue ;D

Hi kentaromiura,

I had this problem when using Ninject in a .NET 3.5 project - to
compile Ninject for .NET 3.5, you'll need to add the NET_35
preprocessor flag to build process of the Core project (and possible
the Test project too if memory serves).

There's a submitted issue already to make this a little easier to do (http://bugs.ninject.org/jira/browse/NINJECT-4
), so track that for any changes.

Cheers,

Michael

Sorry about this, this is definitely a mistake on my part. I incorrectly assumed that the .NET 2.0 build would work for .NET 3.5 as well, but the extension method patch will screw things up. I'll be posting a .NET 3.5 build soon to fix this problem.

Any word on a fix or a manual fix to get around this? Do I just
download the source and pre-pend a preprocessor flag to the build?

Yes, if you define NET_35 in the meantime, it will take care of the problem. I'll fix up the build script in the near future.

I take out of the project the reference to ninject.core and then i
readd ninject.core to the reference, in this way the build process
take the correct dll and don't blame for a while (if later it give
another time the error i repeat the procedure)

I seem to be experiencing the same issue. Trying to use Ninject.Extensions.Conventions from the online NuGet source. When I do I get the errors:

Error    4    Missing compiler required member 'System.Runtime.CompilerServices.ExtensionAttribute..ctor'    C:\Source\Detectachem\Seeker\dchem-platform\DChem.Platform\CSC    DChem.Platform

The project is .NET 4 heading into a WPF application. Is there an alternate, cleaner source?

Hi,

Mostly this situation occurs with particular versions of Mono mixing .NET 2.0 and 3.5 etc.

If you're on the latest version, and there are no Mono builds in the mix (anywhere), there's no common reason for this to occur.

Can you tell us a little more about what versions of things you're using where?
