I am migrating .NET code that was running against 9.3, to make it work for 10.1.
There is part of the code that is failing when migrate to 10.1 and was working on 9.3
The code was doing intersect twice.
The code is like this
The intersection method is wrapped into this method
So the code is calling this method twice
The code is failing on the second statement,
and more specifically when we are calling the intersect method
targetOperator.Intersect(localSourceGeometry, localSourceGeometry.Dimension);
and giving this error
Error HRESULT E_FAIL has been returned from a call to a COM component.
System.Runtime.InteropServices.ExternalException {System.Runtime.InteropServices.COMException}
HResult = -2147467259
