ILSpy
.NET Decompiler with support for PDB generation, ReadyToRun, Metadata
ILSpy is the open-source .NET assembly browser and decompiler. Visual Studio 2022 ships with decompilation support for F12 enabled by default (using our engine v7.1). In Visual Studio 2019, you have to manually enable F12 support. Go to Tools / Options / Text Editor / C# / Advanced and check Enable navigation to decompiled source. C# for Visual Studio Code ships with decompilation support as well. To enable, activate the setting "Enable Decompilation Support. ILSpy is distributed under the MIT License. Please see the About doc for details, as well as third-party notices for included open-source libraries. Visual Studio 16.3 and later include a version of the .NET (Core) SDK that is managed by the Visual Studio installer - once you update, it may get upgraded too. Please note that ILSpy is only compatible with the .NET 6.0 SDK and Visual Studio will refuse to load some projects in the solution. -

Locale Emulator
Yet another system region and language simulator
Locale Emulator is a tool similar to AppLocale and NTLEA, providing a simulation function that can make an application recognize your OS as in a language other than the real one. It is quite useful when you are trying to play country-specific games. Locale Emulator is compatible with the following systems, both 32 and 64-bit, Windows 7 with Service Pack 1, Windows 8.1, and Windows 10. Locale Emulator supports 32-bit executables running on both 32-bit or 64-bit systems. For example, if you are using 64-bit WinRAR, you will not see the context menu on a RAR file unless you swapped 64-bit WinRAR with the 32-bit version. Clone the repo using Git, install Microsoft Visual Studio 2015 / 2017, open LocaleEmulator.sln, perform build action, clone and build the core libraries, and copy LoaderDll.dll and LocaleEmulator.dll from Locale-Emulator-Core to Locale-Emulator build folder. -

BepInEx
Unity / XNA game patcher and plugin framework
Unity / XNA game patcher and plugin framework. BepInEx is a plugin / modding framework for Unity Mono, IL2CPP, and .NET framework games (XNA, FNA, MonoGame, etc.) Stable builds are released once a new iteration of BepInEx is considered feature-complete. They have the least bugs, but some newest features might not be available. Bleeding edge builds are available on BepisBuilds. Bleeding edge builds are always the latest builds of the source code. Thus they are the opposite to stable builds: they have the newest features and bugfixes available, but usually tend to be the most buggy. Therefore you should use bleeding edge builds only if you are asked to or if you want to preview the upcoming version of BepInEx. Some games require some additional changes in order to work around specific limitations of different Unity versions. -

tModLoader
A mod to make and play Terraria mods. Supports Terraria 1.4
tModLoader (TML) is an open-source, community-driven, modification and expansion of the Terraria game that makes it possible to make and play mods. TML expands your Terraria adventures with new content to explore created by the Terraria community! TML allows players to create and play Terraria mods and is designed in such a way so that you can play alone or together with friends, with one mod or with multiple mods, choose to play however you like! It is however required that all your friends also install TML if you want to play together; vanilla users can't play with TML users. First and foremost, TML is largely a community endeavor, built by the community; used by the community. Without all the contributions people in the community have made over the years, TML would not be in the state it is in. TML is a free-to-use modification of the game and will stay that way. -

Dependencies
A rewrite of the old legacy software "depends.exe" in C# for Windows
Dependencies is a rewrite of the legacy software Dependency Walker which was shipped along Windows SDKs, but whose development stopped around 2006. Dependencies can help Windows developers troubleshooting their dll load dependencies issues. Dependencies is currently shipped as two binaries (no installer present) : Dependencies.exe as a CLI tool and DependenciesGui.exe for its GUI counterpart (see screenshot). Just click on one of the release numbers above (preferably the latest), download and uncompress the archive and run DependenciesGui.exe. Since the binary is not signed, SmartScreen might scream at runtime. Dependencies also bundle ClrPhTester.exe, a dumpbin-like executable used to test for non-regressions. Dependencies currently does not recursively resolve child imports when parsing a new PE since it can be really memory-hungry to do so ( it can over a GB even for "simple" PEs ). -

VSCodium
binary releases of VS Code without MS branding/telemetry/licensing
Microsoft’s vscode source code is open source (MIT-licensed), but the product available for download (Visual Studio Code) is licensed under this not-FLOSS license and contains telemetry/tracking. The VSCodium project exists so that you don’t have to download+build from source. This project includes special build scripts that clone Microsoft’s vscode repo, run the build commands, and upload the resulting binaries for you to GitHub releases. These binaries are licensed under the MIT license. Telemetry is disabled. If you want to build from source yourself, head over to Microsoft’s vscode repo and follow their instructions. VSCodium exists to make it easier to get the latest version of MIT-licensed VSCode. Please note that some Visual Studio Code extensions have licenses that restrict their use to the official Visual Studio Code builds and therefore do not work with VSCodium. -

Selenium
Browser automation framework and ecosystem
Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should) also be automated as well. If you want to create robust, browser-based regression automation suites and tests, scale and distribute scripts across many environments, then you want to use Selenium WebDriver, a collection of language specific bindings to drive a browser - the way it is meant to be driven. If you want to create quick bug reproduction scripts, create scripts to aid in automation-aided exploratory testing, then you want to use Selenium IDE; a Chrome and Firefox add-on that will do simple record-and-playback of interactions with the browser. If you want to scale by distributing and running tests on several machines and manage multiple environments from a central point. -

OpenTabletDriver
Open source, cross-platform, user-mode tablet driver
OpenTabletDriver is an open-source, cross-platform, user mode tablet driver. The goal of OpenTabletDriver is to be cross-platform as possible with the highest compatibility in an easily configurable graphical user interface. OpenTabletDriver functions as two separate processes that interact with each other seamlessly. The active program that does all of the tablet data handling is OpenTabletDriver.Daemon. The daemon must be started in order for anything to work, however, the GUI is unnecessary. If you have existing settings, they should apply when the daemon starts. The requirements to build OpenTabletDriver are consistent across all platforms. Running OpenTabletDriver on each platform requires different dependencies. Run build.ps1 to produce binary builds to 'bin' folder. These builds will run in portable mode by default. -
