🧰 Installation

    dotnet add package dymaptic.GeoBlazor.Core

Or for the Pro version with additional features:

    dotnet add package dymaptic.GeoBlazor.Pro

Note: .NET 9 can cause very slow build times due to its new static asset compression. If you need faster builds, we recommend staying on .NET 8 for now, and using a global.json file to pin your SDK build version to .NET 8. See our open request for a fix here.

If you decide to stay with .NET 9, we suggest adding the following line to your csproj file to disable the new compression feature:

   <PropertyGroup>
       <CompressionEnabled Condition="$(Configuration) != 'RELEASE'">false</CompressionEnabled>
   </PropertyGroup>

🏁 Getting Started

(from https://docs.geoblazor.com/pages/gettingStarted.html)

  1. Create a new Blazor Web App, Blazor Server, Blazor Wasm, or Blazor Hybrid (MAUI) project.

  2. Add a PackageReference to the latest version of the dymaptic.GeoBlazor.Core or dymaptic.GeoBlazor.Pro (pro is a paid version with more features) package via your IDE's Nuget Package Manager or from the command line with dotnet add package dymaptic.GeoBlazor.Core (or dotnet add package dymaptic.GeoBlazor.Pro). For Blazor Web Apps supporting WebAssembly, add this reference to the .Client WebAssembly project, or a Razor Class Library where you intend to write your mapping Razor components.

  3. Get an API Key from the ArcGIS Location Platform. Place this in your appsettings.json, secrets.json (user secrets), or environment variables.:

    {
    "ArcGISApiKey": "YourArcGISApiKey"
}

  4. Register at licensing.dymaptic.com for a free GeoBlazor Core Registration key. Add the key to appsettings.json:

        {
        "ArcGISApiKey": "YourArcGISApiKey",
        "GeoBlazor": {
            "RegistrationKey": "YourGeoBlazorRegistrationKey"
        }
    }

  5. In the root file that defines your html (App.razor for Blazor Web Apps, _Layout.cshtml for older Blazor Server apps, and index.html only for standalone Blazor WebAssembly apps), add the following to the <head> section:

    <link href="_content/dymaptic.GeoBlazor.Core"/>
<link href="_content/dymaptic.GeoBlazor.Core/assets/esri/themes/light/main.css" rel="stylesheet" />
<link href="YourProject.styles.css" rel="stylesheet" />

    The YourProject.styles.css is the default stylesheet for your project, this line should already be present in your template, but is important for GeoBlazor to function correctly. For dark mode, replace assets/esri/themes/light/main.css with assets/esri/themes/dark/main.css.

    Starting in .NET 9, there is also a new static asset compression feature that uses an Assets dictionary. If you see this pattern, follow the same pattern for GeoBlazor links:

    <link href="@Assets["_content/dymaptic.GeoBlazor.Core"]"/>
<link href="@Assets["_content/dymaptic.GeoBlazor.Pro"]" />
<link href="@Assets["_content/dymaptic.GeoBlazor.Core/assets/esri/themes/light/main.css"]" rel="stylesheet" />
<link href="@Assets["YourProject.styles.css"]" rel="stylesheet" />

  6. In _Imports.razor (for both Server and Client projects, if applicable), add the GeoBlazor namespaces:

    @using dymaptic.GeoBlazor.Core
@using dymaptic.GeoBlazor.Core.Attributes
@using dymaptic.GeoBlazor.Core.Components
@using dymaptic.GeoBlazor.Core.Components.Geometries
@using dymaptic.GeoBlazor.Core.Components.Layers
@using dymaptic.GeoBlazor.Core.Components.Popups
@using dymaptic.GeoBlazor.Core.Components.Renderers
@using dymaptic.GeoBlazor.Core.Components.Symbols
@using dymaptic.GeoBlazor.Core.Components.Views
@using dymaptic.GeoBlazor.Core.Components.Widgets
@using dymaptic.GeoBlazor.Core.Enums
@using dymaptic.GeoBlazor.Core.Events
@using dymaptic.GeoBlazor.Core.Exceptions
@using dymaptic.GeoBlazor.Core.Extensions
@using dymaptic.GeoBlazor.Core.Functions
@using dymaptic.GeoBlazor.Core.Interfaces
@using dymaptic.GeoBlazor.Core.Model
@using dymaptic.GeoBlazor.Core.Options
@using dymaptic.GeoBlazor.Core.Results

  7. In Program.cs (for both Server and Client projects, if applicable), register the GeoBlazor services:

    builder.Services.AddGeoBlazor(builder.Configuration);

  8. GeoBlazor requires Interactive Server or WebAssembly rendering enabled when using the modern Blazor Web App templates. Verify that the following lines are present in your Program.cs. (This is not relevant if you are using the older Blazor Server template, and does not apply to WebAssembly projects).

    // Server
builder.Services.AddRazorComponents()
    .AddInteractiveServerComponents();

// or WebAssembly
builder.Services.AddRazorComponents
    .AddInteractiveWebAssemblyComponents();

// or both
builder.Services.AddRazorComponents()
    .AddInteractiveServerComponents()
    .AddInteractiveWebAssemblyComponents();

    and in the lower portion of the file:

    // Server
app.MapRazorComponents<App>()
    .AddInteractiveServerRenderMode();

// or WebAssembly
app.MapRazorComponents<App>()
    .AddInteractiveWebAssemblyRenderMode()
    .AddAdditionalAssemblies(typeof(Counter).Assembly);

// or both
app.MapRazorComponents<App>()
    .AddInteractiveServerRenderMode()
    .AddInteractiveWebAssemblyRenderMode()
    .AddAdditionalAssemblies(typeof(Counter).Assembly);

  9. Create a Razor Component page with a map. Again for Blazor Web Apps, be sure that the @rendermode is defined at the page or app level (line 2 of the example below). This should be InteractiveServer for Blazor Server, InteractiveWebAssembly for Blazor WebAssembly, or InteractiveAuto for the automatic switching between modes. Learn more about Blazor render modes.

    @page "/map"
@rendermode InteractiveServer

<MapView Longitude="-118.805" Latitude="34.027" Zoom="11" Style="height: 400px; width: 100%;"> 
    <WebMap>
        <PortalItem PortalItemId="4a6cb60ebbe3483a805999d481c2daa5" />
    </WebMap>
    <ScaleBarWidget Position="OverlayPosition.BottomLeft" />
</MapView>

  10. Run your application and see your map!
