Данная статья расскажет о предназначении папки .mono, которую вы можете заметить у себя на локальном диске.

Папка .mono — что это такое?

Папка компонента, связанного с .NET Framework, который необходим для работы некоторых приложений, игр. Папка может появиться например после установки игры Robocraft.

Стандартное расположение папки:

Директория может быть скрытой.

На самом деле Mono — некий проект, который занимается системой, основанной на .NET Framework. Простыми словами это компонент, который используется при создании некоторых программ, игр. Само по себе ПО .NET Framework от Microsoft — платформа, которая необходима для работы многих программ, включая игры.

Каталог .mono, расположенный в директории игры Hearthstone:

Также может быть в директории ProgramData:

Папка .mono — можно ли удалить?

Если папка весит немного — не стоит удалять, лучше оставить, она может понадобиться для работы некоторого ПО. Когда директория имеет большой размер — лучше сперва создать точку восстановления, а потом уже удалять.

Точку восстановления создавать очень желательно (в случае проблем сэкономит время и сохранит нервы):

1. Откройте панель управления, можно например так: зажмите Win + R > введите команду control или control panel > кликните ОК.
2. Найдите и запустите значок Система.
3. Далее кликните слева Защита системы.
4. Выберите системный диск (обычно имеет букву C) > нажмите кнопку Создать.
5. Назовите точку восстановления, можно просто указать название До удаления папки .mono.

Заключение

1. Папка .mono — относится к платформе .NET Framework, необходима для работы софта, например игр, некоторых приложений.
2. Если размер директории .mono небольшой — лучше оставить, не удалять.
3. При удалении лучше заранее создать точку восстановления.

Install Mono on Windows

Mono runs on Windows, this page describes the various features available for users who want to use Mono on Windows as well as using Mono-based technologies on Windows without Mono (like Gtk#).

Download the latest Windows installer from the download page.

Run the installer and accept the terms of the license. Mono is now installing:

The installer creates a “Open Mono Command Prompt” shortcut under the Mono program group in the start menu. This shortcut starts a command shell with Mono-relevant path information already configured, which means all the Mono tools “just work”.

At this point, it’s a good idea to run through the basic hello world examples on this page to verify Mono is working correctly.

Gtk# is included as part of the Mono installation, this will allow you to create Gtk# applications on Windows with the Mono runtime which you can later deploy into Linux. See the Gtk# page for more details about the toolkit, or go directly to the Gtk# beginner’s guide.

Alternatively, if you only want to use Gtk# on Windows, without Mono, you can use the Gtk# installer for the .NET Framework.

Mono in the Windows 10 Bash

Windows 10 Anniversary Update and greater come with an experimental, optional Linux subsystem that exposes bash as an alternative shell. This can be used to install the Debian/Ubuntu version of Mono alongside or instead of the Windows version. Note that this feature is in beta and you need to manually enable it. For more information about how to install Mono inside Windows Bash and known problems, refer to this issue.

Download

The latest Stable Mono release is: 6.12.0 Stable (6.12.0.122)

Please choose your operating system to view the available packages. Source code is available on GitHub (viewing only) or as a Tarball.

macOS Linux Windows Docker

Mono for macOS is available as a Mac Package (.pkg)

Please refer to the installation guide for more information about how to install and configure your Mono environment.

Supported on macOS 10.9 and later. Check the uninstall instructions if you want to remove Mono from your Mac.

* We recommend this package if you’re using Visual Studio for Mac since the stability of Visual Studio for Mac is only guaranteed with the Visual Studio channel releases.

1 Add the Mono repository to your system

The package repository hosts the packages you need, add it with the following commands.

Note: the packages should work on newer Ubuntu versions too but we only test the ones listed below.

Ubuntu 20.04 (amd64, armhf, arm64, ppc64el)

Ubuntu 18.04 (i386, amd64, armhf, arm64, ppc64el)

Ubuntu 16.04 (i386, amd64, armhf, arm64, ppc64el)

2 Install Mono

The package mono-devel should be installed to compile code.

The package mono-complete should be installed to install everything — this should cover most cases of «assembly not found» errors.

The package mono-dbg should be installed to get debugging symbols for framework libraries — allowing you to get line numbers in stack traces.

The package referenceassemblies-pcl should be installed for PCL compilation support — this will resolve most cases of «Framework not installed: .NETPortable» errors during software compilation.

The package ca-certificates-mono should be installed to get SSL certificates for HTTPS connections. Install this package if you run into trouble making HTTPS connections.

The package mono-xsp4 should be installed for running ASP.NET applications.

3 Verify Installation

After the installation completed successfully, it’s a good idea to run through the basic hello world examples on this page to verify Mono is working correctly.

Notes

Mono on Linux before 3.12 by default didn’t trust any SSL certificates so you got errors when accessing HTTPS resources. This is not required anymore as 3.12 and later include a new tool that runs on package installation and syncs Mono’s certificate store with the system certificate store (on older versions you had to import Mozilla’s list of trusted certificates by running mozroots —import —sync ). Some systems are configured in a way so that the necessary package isn’t pulled in when Mono is installed, in those cases make sure the ca-certificates-mono package is installed.

Mono for Windows is available as a Windows Installer file

Please refer to the installation guide for more information about how to install and configure your Mono environment.

Supported on Windows 7, 8, 10 or later.

GTK# for .NET

Installer for running Gtk#-based applications on Microsoft .NET:

Mono is available on Docker Hub

The simplest way to get started is:

This will download the latest Mono Docker image, create a container and put you into an interactive shell.

Available tags

There are several tags for selecting the desired Mono version:

• latest — Always points to the latest release
• X.X.X.X — points to a specific version, e.g. 5.8.0.108
• X.X.X — points to the latest version in the X.X.X series, e.g. 5.8.0
• X.X — points to the latest version in the X.X series, e.g. 5.8
• X — points to the latest version in the X series, e.g. 5

The latest version, one minor version before that and the last version before a major version bump are periodically rebuilt by Docker Hub to pull in updates from the base Debian image.

All other version tags are still available, but won’t get those updates so you need to keep your images up to date by running apt update yourself. We encourage you to move to latest Mono releases as soon as they’re available.

Starting with Mono 5.2 we provide a slim variant (e.g. latest-slim ) which only contains the bare minimum to run a simple console app. You can use this as a base and add just what you need.
