A logic bomb is a piece of code intentionally inserted into a software system that will set off a malicious function when specified conditions are met. For example, a programmer may hide a piece of code that starts deleting files (such as a salary database trigger), should they ever be terminated from the company.
Source generators, [78] a feature of the Roslyn C# compiler, enable compile time metaprogramming. During the compilation process, developers can inspect the code being compiled with the compiler's API and pass additional generated C# source code to be compiled.
While most commercial obfuscation solutions transform either program source code or platform-independent bytecode (as used by Java and .NET), some also work directly on compiled binaries. Some Python examples can be found in the official Python programming FAQ and elsewhere. [10] [11] [12]

.NET Compiler Platform, also known by its codename Roslyn, [2] is a set of open-source compilers and code analysis APIs for C# and Visual Basic (VB.NET) languages from Microsoft. [ 3 ] The project notably includes self-hosting versions of the C# and VB.NET compilers – compilers written in the languages themselves.
The Jerusalem virus is considered to be based on Suriv-3, which is a logic bomb triggered when the date is Friday the 13th, switching off the computer on the 13th. In itself, Suriv-3 is based on its predecessors, Suriv-1 and Suriv-2, which are logic bombs triggered on April 1 ( April Fools' Day ), showing text reading "April 1, ha ha you have a ...
As a precursor to the lambda functions introduced in C# 3.0, C#2.0 added anonymous delegates. These provide closure-like functionality to C#. [3] Code inside the body of an anonymous delegate has full read/write access to local variables, method parameters, and class members in scope of the delegate, excepting out and ref parameters. For example:-
