 This package extends [Sentry.Extensions.Logging](/platforms/dotnet/guides/extensions-logging/). This means that besides the MAUI related features, through this package you'll also get access to all the framework's logging integration and also the features available in the main [Sentry](/platforms/dotnet/) SDK.

+
+#### Troubleshooting
+
+The MAUI workloads are updated by Microsoft periodically. When trying to install or update `Sentry.Maui`, you may get errors such as the following:
+
+```
+error: NU1605: Detected package downgrade: Microsoft.Maui.Dependencies from 6.0.400 to 6.0.312. Reference the package directly from the project to select a different version.
+error:  test -> Sentry.Maui 3.18.0-preview.1 -> Microsoft.Maui.Dependencies (>= 6.0.400)
+error:  test -> Microsoft.Maui.Dependencies (>= 6.0.312)
+```
+
+This happens when you have an older version of the `maui` workload than the one that was current when we built the package.
+We are investigating how to avoid this issue in a future release.  For now, you can update your workloads by using the `dotnet workload update` command.  See [this issue](https://github.com/getsentry/sentry-dotnet/issues/1724) for further details.

 ### Configure
 
 In your `MauiProgram.cs` file, call `UseSentry` on your `MauiAppBuilder`, and include any options you would like to set.  The `Dsn` is the only required parameter.
