The file program.cs in project Be.HexEditor (1.4.8) contains the following syntactically invalid statement at about line 14:
public static FormHexEditor FormHexEditor;
The failure to catch this error is caused by a compiler bug. In this particular instance the compiler does notsee that the object name and the object type are identical. The project seems to behave a little better when the statement is changed to something like:
public static FormHexEditor formHexEditor;
This fix requires changing the few places where the object is referenced.
