False error with extensions in partial classes

[Zbynek]

I have ran into false errors with extension method defined inside partial class.
I have attached test code to reproduce the issue. The problem is that second partial class is missing keyword "static". But the code get compiled just fine.

Edit:
The same also happend when one of those classes is missing "public" access modifier and the extension method is used in different assembly.

Zbynek

namespace TestProject
{
    public static partial class Extensions
    {
        //...
    }

    partial class Extensions
    {
        public static void ExtentionMethod(this object obj)
        {
        }
    }


    class Program
    {
        static void Main(string[] args)
        {
            object obj = new object();
            obj.ExtentionMethod();
        }
    }
}

Hello Zbynek,

thanks a lot for your feedback. Can you try with the new beta build (just released today). I could not reproduce the problem with that build so it seems fixed already.

Kind regards,

Hello Hans,
I have tested it with the new version and the result is that half of the problem is fixed.

The only remaining issue is when the extension method is defined inside partial class with missing "public" access modifier.
If you split the example into separate assemblies, one with extension definitions and another where is the extension used you'll get "Unknown method error" on ExtensionMethod call. When you add "public" to the second Extension class definition, the error disappear.

Kind regards
