Install on Blazor Web App

  • Add BlazorApplicationInsights NuGet to the Client project

    • dotnet add package BlazorApplicationInsights

  • Add call to Program.cs in the root and Client project if one exists

    builder.Services.AddBlazorApplicationInsights(x =>
{
    x.ConnectionString = "{Insert Connection String}";
});

  • Add using statement to _Imports.razor

    • @using BlazorApplicationInsights;

  • Add component below <base href="/" /> in App.razor

    • NOTE: Interactivity is necessary only when the optional onAppInsightsInit callback is configured as part of the AddBlazorApplicationInsights setup.
    • <ApplicationInsightsInit @rendermode="@InteractiveAuto" />

Install on Blazor WebAssembly Standalone App

  • Add BlazorApplicationInsights NuGet to the Client project

    • dotnet add package BlazorApplicationInsights

  • Add call to Program.cs and set the ConnectionString

    builder.Services.AddBlazorApplicationInsights(config =>
{
    config.ConnectionString = "{Insert Connection String}";
});

  • Add using statement to _Imports.razor
