Read on for what to install, where the files end up and how a project gets them, from the system requirements to upgrading an existing application. ### How You Get the Product | | Development machine | Build server or CI/CD pipeline | |---|---|---| | What you install | The setup of the full or the trial version | Nothing: only the NuGet package | | .NET 8 or higher projects | Install `TXTextControl.TXSpell.WinForms.SDK` from the local package source **Text Control Offline Packages** | Restore the package from the Text Control Private NuGet Feed or your own feed | | .NET Framework projects | Reference the assemblies in the *Assembly* folder of the installation | Build with the assemblies of the installation | | Visual Studio designer | The setup adds the toolbox tab for .NET Framework projects; the package adds it in .NET projects | Not needed | | Language data | Installed with the setup and brought by the package | Brought by the package | ### The Installation Path 1. Check the [System Requirements](https://docs.textcontrol.com/tx-spell-dotnet-winforms/installation/requirements/llms-full.txt): .NET 8 or higher or the .NET Framework, Windows 10 or 11, and Visual Studio 2022. 2. Run the setup, as [Installing the Product](https://docs.textcontrol.com/tx-spell-dotnet-winforms/installation/setup/llms-full.txt) describes. 3. Install the package in your project, as [Installing and Updating Packages](https://docs.textcontrol.com/tx-spell-dotnet-winforms/installation/nuget/install-update/llms-full.txt) shows, or reference the assemblies in a .NET Framework project. 4.
