Installation — ReoGrid Docs

Requirements

.NET 10 SDK or later (10.0.301 or above). net48 / net8 are not supported
The WinForms and WPF editions are Windows-only. The Avalonia and headless editions run on Windows / Linux / macOS

Choosing a package

You are building	Package
A WinForms app	`unvell.ReoGrid.One`
A WPF app	`unvell.ReoGrid.One.Wpf`
An Avalonia app (cross-platform)	`unvell.ReoGrid.One.Avalonia`
Server / batch processing (no UI)	`unvell.ReoGrid.One.Core`

The UI packages include everything — the core, the formula engine and XLSX / PDF I/O. There is no need to reference .Core alongside them (it would be a duplicate reference).

Registering the package feed

The packages are not on nuget.org; they come from UNVELL’s package feed. Register the feed as a NuGet source once, before the first install.

Create a token under Access Tokens in the portal
Register the feed, with your portal email address as the user name and the token as the password

dotnet nuget add source "https://packages.unvell.com/nuget/v3/index.json" \
  --name reogrid \
  --username "[email protected]" \
  --password "<access token>" \
  --store-password-in-clear-text

The same portal page shows this command with your address and token filled in, and a nuget.config example. On CI, pass the token in from an environment variable or a secret.

Installing

dotnet add package unvell.ReoGrid.One

The current version is 5.2.0.

To add it directly to your .csproj:

<ItemGroup>
  <PackageReference Include="unvell.ReoGrid.One" Version="5.2.0" />
</ItemGroup>

WinForms / WPF projects need the target framework set and the UI enabled.

<PropertyGroup>
  <TargetFramework>net10.0-windows</TargetFramework>
  <UseWindowsForms>true</UseWindowsForms>   <!-- for WPF: <UseWPF>true</UseWPF> -->
</PropertyGroup>

Namespaces

Each package is a single DLL, but the namespaces are organized by feature.

Namespace	Contents
`unvell.ReoGrid.Core`	`Workbook`, `Worksheet`, `CellPosition`, `RangePosition`
`unvell.ReoGrid.Core.Style`	`StyleRecord`, `HAlign`, `VAlign`, `TextWrap`
`unvell.ReoGrid.Core.Data`	`CellValue`, `CellValueKind`
`unvell.ReoGrid.Core.CellTypes`	Cell types such as checkboxes and dropdowns
`unvell.ReoGrid.Core.License`	`ReoGridLicense`, `LicenseInfo`
`unvell.ReoGrid.WinForms`	The WinForms `ReoGridControl`
`unvell.ReoGrid.Wpf`	The WPF `ReoGridControl`
`unvell.ReoGrid.Avalonia`	The Avalonia `ReoGridControl`
`unvell.ReoGrid.IO.Excel`	`XlsxReader`, `XlsxWriter`
`unvell.ReoGrid.IO.Pdf`	`PdfExporter`

Assembly names

The package ID and the assembly name (DLL name) match. For example, unvell.ReoGrid.One is unvell.ReoGrid.One.dll. Use this name when referencing the assembly from XAML (WPF / Avalonia).

In V4, the WinForms and WPF editions shared the same DLL name, unvell.ReoGrid.dll; in V5 they are separate.

The WinForms package also carries the native DLL for Direct2D drawing (runtimes/win-x64/native/d2dlib64.dll, runtimes/win-x86/native/d2dlib32.dll). With a NuGet reference it is copied into your output automatically; an app that draws only with GDI+ runs without it.
