支持对象类型的.Net的第三方Oracle提供程序

I'm looking for a third-party Oracle Data Provider for .Net (ADO.NET) with a full support of Oracle object types (like geometries). I was foolish enough to use ODP.NET and now I'm paying the price - it's incredibly buggy and I just reached the end of the line (keep crashing IIS Pool - known issue, no resolution). I found dotConnect which is fine, just 4 times slower with object types than ODP.NET. Are any others providers which support Oracle objects?I'm looking for a third-party Oracle Data Provi
