NotSupportedException

This ILGenerator belongs to a DynamicMethod.

Line numbers are indexed from 1. Columns are indexed from 0.

The symbolic information normally includes at least one MSIL offset for each source line. When the just-in-time (JIT) compiler is about to compile a method, it asks the profiling services for a list of MSIL offsets that should be preserved. These MSIL offsets are called sequence points.

If the current ILGenerator is associated with a DynamicMethod object, it does not support symbolic information.
