https://visualstudio.microsoft.com/vs/community/ Although it is possible to make games without Visual Studio or Rider, doing so requires advanced knowledge of MSBuild. We recommend downloading and installing Visual Studio Community which is free.
At a minimum you will need to install .NET desktop development.
Visual Studio 2022 (as of version 17.5.1) installs .NET SDK 7.0 which has a bug preventing projects from being loaded in the FlatRedBall Editor. Therefore, you will need to manually install .NET 6 SDK.
The most common approach to making FlatRedBall games is to use the FlatRedBall Editor. The Editor can be downloaded from a pre-built .zip file, or it can be built from source. New users should download the pre-built .zip file.
Alternatively, the FlatRedBall Editor (no additional tools) prebuilt can be downloaded from Github. This is not recommended for new users, but experienced users can replace the FlatRedball Glue folder with the contents from the built files: https://github.com/vchelaru/FlatRedBall/actions
Unzip the file after downloading
Go to the folder where the .zip file unzipped to (by default called FRBDK)
Open the Run FlatRedBall.bat file (double click it)
