Blogged: Making foreach of an IEnumerable allocation-free, using reflection and dynamic methods
andrewlock.net/making-foreac…
In this post I describe why foreach sometimes allocates, and show how you can use DynamicMethod and Reflection.Emit to go allocation-free

Unfortunately, I have seen several samples in the wild (advanced first-stage loader) using this technique simple obfuscation AMSI Bypass via DInvoke. Advantage - NO direct references to “System.Reflection.Assembly.Load()” method
#dotnet #reversing #malware #DynamicMethod
[DynamicDotNet Tooling] Added a POC "Dynamic Assembly Loader" to the repo that loads and executes an assembly using a dynamic method and emitted MSIL instructions (C#).
System.Reflection.Emit is quite powerful (maybe more to come in a future blog post)

Well when such a use case does come up, it's a bit maddening to have to reach for a more complex DynamicMethod or IL weaver knowing that feature is already hiding in the compiler.

It lookes like EVM->IL->ASM doesn't look that bad at all. Of course there are few things to optimize but still.
Thank you @KooKiz for helping me with getting the ASM behind the dynamic method.

Since .NET 5 you can dump the IL of a DynamicMethod with !dumpil, but I'm not sure how to jump to the native assembly from there 🤔 One way could be to create a delegate, locate it, then follow the jumps in the disassembly, but that's hard to automatize.

Last speed day before hitting the big 5-RM!!! 315 felt like a rocket!!! Rate of force development is crucial for maximal effort ability!!! wenningstrength.com #wenning #bench #speed #dynamicmethod #powerlifting #powerbuilding instagr.am/p/CE67NxPl3ZV/

Given that almost each test creates the expression tree and _compiles_ it to the DynamicMethod, I think the result is kinda neat.

also, even if you're not on .NET Core you need to be careful with DynamicMethod etc; different frameworks/versions accept different signatures; "ref return" is only supported recently, for example, despite being perfectly valid (the change was literally to just remove the check)

Inline #MSIL (Microsoft #IL) in #PowerShell (by utilizing C# & DynamicMethod)
E.g.: Decoding Base64 using System.Convert.FromBase64String
*In the @FireEye report about new #APT29 phishing campaign, I saw they used "FromBase" 0x40 "String" to evade detection. Find the call now!
