I spent my Saturday on a dumb project answering the following question:
What is the smallest #dotnet Hello World binary?
Turns out, this rabbit hole is deeper than you may expect, so I wrote a blog post about it:

#AsmResolver 5.3.0 is out!
More performance and #pe reader bugfixes, new docs, and we also made it easier to ignore errors when writing #dotnet modules.

I thought it was time to show off some of #AsmResolver's new #native #PE #patching API. In this blog, we discuss how to programmatically inject code into an arbitrary PE, and learn how to construct new import directories as we go.
Patching PE files is easy. Injecting new code that uses functions from external modules, however, is more complicated. In this post, we are implementing a method for rebuilding import directories, such that we can inject any type of code in an arbitrary PE file.
#AsmResolver 5.1.0 just got released!
This version brings support for C#11 generic custom attributes as well as a fluent binary #patching API for both #dotnet and native #PE files. We are slowly making native PE reconstruction a lot easier!

Time for another blog post!
This time we are tackling .NET debuggers and make them display garbage data with the help of proxy objects and debugger display attributes.

.NET decompilers and debuggers have become very good at helping reverse engineers figure out the inner workings of a program. However, they also make a lot of assumptions that can be used against them. In this post, we will explore a method that can be used to trick the debugger into hiding a lot of important information during a debugging session.
