Feature creation error

[MarcoGiorgi]

When I try to create GeoJSON file from a SQL Server table with the geographies of the world countries, I get the following error on both the Russian Federation and Antarctica:

Exception has been thrown by the target of an invocation. at System.RuntimeMethodHandle.InvokeMethod(Object target, Object[] arguments, Signature sig, Boolean constructor) at System.Reflection.RuntimeMethodInfo.UnsafeInvokeInternal(Object obj, Object[] parameters, Object[] arguments) at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture) at System.Data.Entity.SqlServer.SqlSpatialServices.GetSpatialTypeName(DbGeometry geometryValue) at alatas.GeoJSON4EntityFramework.GeoJsonGeometry._Closure$__13-0._Lambda$__0(Type t) in C:\a\1\s\GeoJSON4EntityFramework\Base\GeoJsonGeometry.vb:line 31 at System.Linq.Enumerable.WhereSelectArrayIterator2.MoveNext()

They are not the biggest geographies I have in the DB because USA, Canada, and Australia, for example, are much bigger in terms of the number of polygons and points.

I've tried to reduce their size, but I still get the error.
The geographies are valid and made only by Polygons (they are MULTIPOLYGON type)

I've tried also to convert the Geography field to a Geometry, but I get always the same error:

What could be the cause?

I think I've found the reason of the bug: the library it's not able to parse geography data that is crossing the +-180 meridian.

Here a simple WKT to reproduce the issue:
