## Install the required version of the .NET Core SDK
Go to https://dotnet.microsoft.com/download/visual-studio-sdks and install the latest version of the .NET Core SDK compatible with Avalonia UI. Make sure to download the SDK (not just the "runtime") package. The version compatible is indicated within the [global.json](https://github.com/AvaloniaUI/Avalonia/blob/master/global.json) file. Note that Avalonia UI does not always use the latest version and is hardcoded to use the last version known to be compatible (SDK releases may break the builds from time-to-time).
### Open in Visual Studio
## Build and Run Avalonia
Open the `Avalonia.sln` solution in Visual Studio 2022 or newer. The free Visual Studio Community edition works fine. Build and run the `Samples\ControlCatalog.Desktop` or `ControlCatalog.NetCore` project to see the sample application.
```
cd samples\ControlCatalog.NetCore
dotnet restore
dotnet run
```
## Opening in Visual Studio
### Troubleshooting
If you want to open Avalonia in Visual Studio you have two options:
- Avalonia.sln: This contains the whole of Avalonia in including desktop, mobile and web. You must have a number of dotnet workloads installed in order to build everything in this solution
- Avalonia.Desktop.slnf: This solution filter opens only the parts of Avalonia required to run on desktop. This requires no extra workloads to be installed.
Avalonia requires Visual Studio 2022 or newer. The free Visual Studio Community edition works fine.
Build and run `ControlCatalog.NetCore` project to see the sample application.

MonoDevelop, Xamarin Studio and Visual Studio for Mac aren't capable of properly opening our solution. You can use Rider (at least 2017.2 EAP) or VSCode instead. They will fail to load most of platform specific projects, but you don't need them to run on .NET Core.

### Additional requirements for macOS
## Additional requirements for macOS
The build process needs [Xcode](https://developer.apple.com/xcode/) to build the native library. Following the install instructions at the [Xcode](https://developer.apple.com/xcode/) website to properly install.
On macOS it is necessary to build and manually install the respective native libraries using [Xcode](https://developer.apple.com/xcode/). Execute the build script in the root project with the `CompileNative` task. It will build the headers, build the libraries, and place them in the appropriate place to allow .NET to find them at compilation and run time.
