One method is DLL preloading or a binary planting attack. It places DLL files with the same name in a location that is searched earlier, such as the current working directory. When the vulnerable program tries to load the DLL, the malicious version is executed, possibly at high privilege levels if the program runs at that level. [6]
A dynamic-link library (DLL) is a shared library in the Microsoft Windows or OS/2 operating system.A DLL can contain executable code (functions), data, and resources.. A DLL file often has file extension.dll even though this is not required.
Programs written in C#, Visual Basic.NET, C++/CLI and other .NET languages require the .NET Framework. It has many libraries (one of them is mscorlib.dll – Multilanguage Standard Common Object Runtime Library, formerly Microsoft Common Object Runtime Library [20]) and so-called assemblies (e.g. System.Windows.Forms.dll).
Dynamic loading is a mechanism by which a computer program can, at run time, load a library (or other binary) into memory, retrieve the addresses of functions and variables contained in the library, execute those functions or access those variables, and unload the library from memory.
In computer programming, DLL injection is a technique used for running code within the address space of another process by forcing it to load a dynamic-link library. [1] DLL injection is often used by external programs to influence the behavior of another program in a way its authors did not anticipate or intend.
In most Unix-like systems, most of the machine code that makes up the dynamic linker is actually an external executable that the operating system kernel loads and executes first in a process address space newly constructed as a result of calling exec or posix_spawn functions. At link time, the path of the dynamic linker that should be used is ...

The resulting C# wrapper has the similar interface of the C++ counterpart with the parameter type converted to the .NET code. This tool recognizes template classes which is not exported from the C++ DLL and instantiates the template class and export it in a supplement DLL and the corresponding C++ interface can be used in .NET.
