# Blazor WebAssembly | Sentry for Blazor WebAssembly

Sentry provides an integration with Blazor WebAssembly through the [Sentry.AspNetCore.Blazor.WebAssembly NuGet package](https://www.nuget.org/packages/Sentry.AspNetCore.Blazor.WebAssembly).

## [Install](https://docs.sentry.io/platforms/dotnet/guides/blazor-webassembly.md#install)

Error Monitoring\[ ]Tracing

Add the Sentry dependency to your Blazor WebAssembly application:

```shell
dotnet add package Sentry.AspNetCore.Blazor.WebAssembly -v 6.3.1
```

This package extends [Sentry.Extensions.Logging](https://docs.sentry.io/platforms/dotnet/guides/extensions-logging.md). This means that in addition to the related Blazor WebAssembly features, you'll also get access to the `ILogger<T>` integration and other features available in the main [Sentry](https://docs.sentry.io/platforms/dotnet.md) SDK through this package.

## [Configure](https://docs.sentry.io/platforms/dotnet/guides/blazor-webassembly.md#configure)

Sentry integration with Blazor WebAssembly is done by calling `.UseSentry()` and specifying the options, for example:

```csharp
using Microsoft.AspNetCore.Components.WebAssembly.Hosting;
using Microsoft.Extensions.Logging;

var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.UseSentry(options =>
{
    options.Dsn = "___PUBLIC_DSN___";
    // When configuring for the first time, to see what the SDK is doing:
    options.Debug = true;
    // Adds request URL and headers, IP and name for users, etc.
    options.SendDefaultPii = true;
    // ___PRODUCT_OPTION_START___ performance
    options.TracesSampleRate = 0.1;
    // ___PRODUCT_OPTION_END___ performance
});

// Captures logError and higher as events
builder.Logging.AddSentry(o => o.InitializeSdk = false);

await builder.Build().RunAsync();
```

## [Verify](https://docs.sentry.io/platforms/dotnet/guides/blazor-webassembly.md#verify)

This snippet includes an intentional error, so you can test that everything is working as soon as you set it up.

```csharp
try
{
    throw null;
}
catch (Exception ex)
{
    SentrySdk.CaptureException(ex);
}
```
