PluginDevHelper

Simple utility that allows you to automatically unload/reload an x64dbg plugin while developing with Visual Studio.

Installation

Start PluginDevServer and keep it running in the background
Install the PluginDevHelper plugin
Nativate to you plugin's Properties -> Build Events in Visual Studio
Pre-Link Event -> Command Line: if exist "$(ProjectDir)PluginDevBuildTool.exe" ("$(ProjectDir)PluginDevBuildTool.exe" unload "$(TargetPath)")
Post-Build Event -> Command Line: if exist "$(ProjectDir)PluginDevBuildTool.exe" ("$(ProjectDir)PluginDevBuildTool.exe" reload "$(TargetPath)")
Create a symbolic link (mklink or Link Shell Extension) to you plugin's output file in x64dbg's plugins directory
Copy PluginDevBuildTool.exe next to your .vcxproj file

Expected behavior

When building the plugin with Visual Studio and the output file is loaded in an open x64dbg instance:

1>------ Build started: Project: XmmYmm, Configuration: Release Win32 ------
1>plugin.cpp
1>PluginDevBuildTool: Failed to obtain exclusive access, requesting to unload XmmYmm.dp32
1>PluginDevBuildTool: Exclusive access to XmmYmm.dp32 obtained!
1>   Creating library C:\Projects\XmmYmm\bin\x32\XmmYmm.lib and object C:\Projects\XmmYmm\bin\x32\XmmYmm.exp
1>Generating code
1>Finished generating code
1>XmmYmm.vcxproj -> C:\Projects\XmmYmm\bin\x32\XmmYmm.dp32
1>PluginDevBuildTool: Requested reload of XmmYmm.dp32
========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========

From x64dbg's perspective:

[PluginDevHelper] PluginDevHelper: plugunload "XmmYmm"
[PLUGIN] XmmYmm.dp32 unloaded
[PluginDevHelper] PluginDevHelper: plugload "XmmYmm"
[PLUGIN, XmmYmm] Expression function "xmm" registered!
[PLUGIN] XmmYmm v1 Loaded!

Virus total flags this as a trojan

Hey, I did 2 different checks as my antivirus (windows) started screaming.

There are some unexplained external ip calls. I have looked at the code, and didn't see any. How is that possible? what is going on there?

curRetry is always 0

static DWORD WINAPI WebSocketThread(LPVOID)
{
	using namespace std::chrono_literals;
	// this can happen when code becomes stale and we need to re-establish connection again
	int curRetry = 0;
	while (curRetry < MAX_RETRIES) {
		std::this_thread::sleep_for(500ms);
		// connection successful or stop signal received after retry
		if (ConnectToSocket() || bStopWebSocketThread) {
			return 0;
		}
	}
	return 0;
}

should add curRetry++
