###### Note: VS Code is not currently supported.
## Getting Started
- Install prerequisite [requirements](https://github.com/modernuo/ModernUO#requirements)
- Clone this repository (or download the [latest](https://github.com/modernuo/ModernUO/archive/refs/heads/main.zip)):
- `git clone https://github.com/modernuo/ModernUO.git`
- Open `ModernUO.sln` to start developing
## Building/Publishing
- Run `./publish.cmd [release|debug (default: release)] [os]`
- `os` - [Supported operating systems](https://github.com/dotnet/core/blob/main/release-notes/6.0/supported-os.md)
- `win` - Windows 10/11/2016/2019/2022
- `osx` - MacOS 10.15/11.0+/12.0+ (Catalina, Big Sur, Monterey)
- `ubuntu.16.04`, `ubuntu.18.04` `ubuntu.20.04` - Ubuntu LTS
- `linuxmint.17`, `linuxmint.18`, `linuxmint.19` - Linux Mint
- `debian.10`, `debian.11` - Debian
- `centos.7`, `centos.8` - CentOS
- `fedora.32`, `fedora.33`, `fedora.34` - Fedora
- `rhel.7`, `rhel.8` - Redhat
- If blank, the operating system running the build is used. Linux Mint 20 is not supported directly yet, so build explicitly against `ubuntu.20.04` instead.
**Note:** Building in Visual Studio (or Rider) will not run the schema migration. The schema migration ensures future changes
to the code will be backward compatible.
## Running the Server
- Follow the [publish](https://github.com/modernuo/ModernUO#publishing-builds) instructions
- Run `ModernUO.exe` or `dotnet ModernUO.dll` from the `Distribution` directory on the server
**Note:** If you are running a version of linux that isn't listed above, then you may have to install the following using a package manager:
* `libargon2-dev`, `libz-dev`, and `zstd`
