# PVS\-Studio C\# installation on Linux and macOS

**Note**\. To install the analyzer on Windows operating systems, you can use the installer available on the analyzer [download page](https://pvs-studio.com/en/pvs-studio/download-all/)\. Windows installer supports installation in both graphical and unattended \(command\-line installation\) modes\.

## PVS\-Studio C\# dependencies

The PVS\-Studio C\# analyzer requires a number of additional packages\. Depending on how PVS\-Studio C\# is installed these dependency packages will be installed automatically by the package manager, or they will need to be installed manually\.

### \.NET SDK

The analyzer requires \.NET SDK 10\.0 installed on a machine\. Instructions for adding the \.NET repository to various Linux distributions [can be found here](https://docs.microsoft.com/en-us/dotnet/core/install/linux)\.

The \.NET SDK for macOS can be downloaded from [this page](https://dotnet.microsoft.com/en-us/download/dotnet/10.0)\.

_**Note\.** When installing pvs\-studio\-dotnet via the package manager on Linux, the version of the \.NET SDK required for the analyzer will be installed automatically, but the \.NET repository must first be added manually\._

### pvs\-studio

The PVS\-Studio C\# analyzer requires the presence of the PVS\-Studio C\+\+ analyzer \(pvs\-studio\) to work\.

_**Note\.** When installing the PVS\-Studio C\# analyzer package \(pvs\-studio\-dotnet\) via the package manager, the C\+\+ analyzer package \(pvs\-studio\) will be installed automatically and you can skip this step\._

When installing the C\# analyzer via unpacking the archive, you must also install the C\+\+ analyzer \(pvs\-studio\)\. The C\+\+ analyzer must be installed in the following directories: 

* Linux: any directory whose path is written in the 'PATH' environment variable;
* macOS: /usr/local/bin/pvs\-studio

Instructions for installing pvs\-studio are available in the corresponding sections of the documentation: [Linux](https://pvs-studio.com/en/docs/manual/0039/), [macOS](https://pvs-studio.com/en/docs/manual/0042/)\.
