 In order to minimize name collisions between names generated based on input to SWIG and names used in the generated code from the .NET framework, SWIG 3 fully qualifies the use of all .NET types. Furthermore, SWIG 3 avoids <tt>using</tt> directives in generated code. This breaks backwards compatibility with typemaps, pragmas, etc written for use with SWIG 2 that assume the presence of <tt>using System;</tt> or <tt>using System.Runtime.InteropServices;</tt> directives in the intermediate class imports, module imports, or proxy imports. SWIG 3 supports backwards compatibility though the use of the <tt>SWIG2_CSHARP</tt> macro. If <tt>SWIG2_CSHARP</tt> is defined, SWIG 3 generates <tt>using</tt> directives in the intermediate class, module class, and proxy class code similar to those generated by SWIG 2. This can be done without modifying any of the input code by passing the <tt>-DSWIG2_CSHARP</tt> commandline parameter when executing <tt>swig</tt>.
