Why are IFMEGeometry canCastAs and castAs giving compile errors

From fmepedia

Q) Why are IFMEGeometry::canCastAs and castAs giving compile errors?

A) IFMEGeometry::canCastAs<T>(…) and IFMEGeometry::castAs<T>(…) use explicit function template arguments which are not supported in VC6 and earlier.

The recommended solution is to upgrade to the latest version of Visual Studio. However to compile in VC6 you can use the following syntax:

dynamic_cast<T>(…) can be used in place of castAs<T>(…)
NULL != dynamic_cast<T>(…) can be used in place of canCastAs<T>(…)
