Overview
BlazorWinOld provides a collection of Blazor components styled to match the iconic Windows interfaces from the late 90s and 2000s. Whether you're building a nostalgia-driven project or need that classic Windows aesthetic, this library delivers pixel-perfect components including buttons, message boxes, windows, tabs, and more.
💡 Already using a UI framework? No problem! BlazorWinOld is fully compatible alongside other UI libraries (MudBlazor, Radzen, Fluent UI…). You can adopt just the components you need, such as
WinOldContextMenuorWinOldMessageBox, without any conflict.

Installation
Install-Package BlazorWinOld
or
dotnet add package BlazorWinOld
For client-side and server-side Blazor - add script section (head section)
<link href="_content/BlazorWinOld/css/blazorwinold.css" rel="stylesheet" />
In Program.cs add this line
builder.Services.AddWinOldComponents();
in _Imports.razor :
@using Blazor.WinOld
@using Blazor.WinOld.Components
and in the bottom of your MainLayout.razor add these lines (optional, only if you use MessageBox or InputBox)
<WinOldMessageBoxHost />
<WinOldInputBoxHost />
<WinOldDialogHost />
CSS utilities
blazorwinold.css also includes a set of layout utility classes (flexbox, grid, gap, responsive sm: / md: / lg: / xl: variants), all prefixed with wo- to avoid conflicts with other CSS frameworks. Nothing to declare:
<div class="wo-col sm:wo-row wo-gap-16">
<div>Column 1</div>
<div class="wo-col wo-gap-8">Column 2</div>
</div>
See the CSS Utilities page of the demo for the full list.
Application layout
WinOldAppShell lays out a classic application in your own MainLayout: menu, toolbar, side pane, content and status bar. Only the side pane and the content scroll. Its Appearance is inherited by the WinOldMenu, WinOldToolbar, WinOldNavPane and WinOldStatusBar placed inside, and it already renders the MessageBox / InputBox / Dialog hosts (IncludeHosts="false" if you declare them yourself):
@inherits LayoutComponentBase
<WinOldAppShell Appearance="Appearance.Win98">
<Menu><WinOldMenu>...</WinOldMenu></Menu>
<Toolbar><WinOldToolbar>...</WinOldToolbar></Toolbar>
<SidePane><WinOldNavPane>...</WinOldNavPane></SidePane>
<StatusBar><WinOldStatusBar>...</WinOldStatusBar></StatusBar>
<ChildContent>@Body</ChildContent>
</WinOldAppShell>
A page can add its own toolbar or status bar with <SectionContent SectionName="@WinOldAppShell.ToolbarSection"> (or StatusBarSection). See the AppShell page of the demo.
Scrollbars
Each appearance has its own scrollbar style: scroll-win-dos, scroll-win-31, scroll-win-98, scroll-win-xp, scroll-win-7, scroll-win-10. Add the class to any scrollable element, or get it with Appearance.ToScrollbarClass():
<div class="@Appearance.Win98.ToScrollbarClass()" style="height: 100px; overflow: auto;">...</div>
For the whole page, put the class on <html> in index.html, or change it at runtime with await JS.SetScrollbarAppearanceAsync(Appearance.Win7); (IJSRuntime). Firefox only gets the colors. See the Scrollbar page of the demo.
