'namespace-name': non-inline namespace cannot be reopened as inline
The inline keyword may be used on a namespace definition extension only if it was also used on the original namespace definition.
To resolve this issue, make the use of the inline specifier consistent across all parts of the namespace.
The following sample generates C2049:
// C2049.cpp
namespace ns {}
inline namespace ns {} // C2049Possible resolution:
// C2049b.cpp
namespace ns {}
namespace ns {}
