Hacking C# from the inside - how to do anything in NET

Adam Furmanek

Bypass C# memory safety to execute raw machine code directly within your app. Neutralize fatal stack overflow exceptions and reshape the .NET framework from the inside.

#1 about 6 min

Overriding dynamic dispatch statically in object-oriented programming

Using intermediate language instructions to statically invoke methods and bypass polymorphic dynamic dispatch.

#2 about 5 min

Awaiting async void methods with custom task schedulers

Implementing custom synchronization contexts and task schedulers to aggregate and safely handle unwieldy async void methods.

#3 about 15 min

Executing raw native machine code directly from byte arrays

Bypassing standard compilers to allocate, unprotect memory, and execute dynamically generated assembly functions via delegate marshalling.

#4 about 5 min

Hijacking method execution paths with machine code replacement

Overriding runtime metadata and using generated intermediate offset jumps to dynamically redirect native execution behavior.

#5 about 6 min

Manipulating private platform constructs for target application placement

Overriding standard platform constructors to securely expose private underlying logic and assign initialized processes onto arbitrary virtual desktops.

#6 about 2 min

Preventing application crashes from unhandled thread exceptions

Intercepting core background object instantiation to automatically inject safety try-catch wrappers around unstable logic threads.

#7 about 4 min

Recovering recursive stack overflows with vectored exception handlers

Preventing hard crashes by registering lower level hardware exception interrupts to actively save and cleanly restore cpu execution context registers.
