How to turn on CircuitOptions.DetailedErrors in C#?

To turn on CircuitOptions.DetailedErrors in a Blazor Server application, you can configure it in the Startup.cs file.

  • In the ConfigureServices method, add the following line of code to register the circuit options:
services.AddServerSideBlazor().AddCircuitOptions(options => { options.DetailedErrors = true; });
  • If you want to enable detailed errors for a specific component only, add the CircuitOptions.DetailedErrors property to the component's CircuitOptions parameter, like this:
@page "/" @attribute [CircuitOptions(DetailedErrors = true)]

With these changes, detailed error messages will be displayed in the browser when an exception is thrown during the execution of a Blazor Server application. This can be very helpful during development, but it's recommended to turn off detailed errors in production environments to avoid exposing sensitive information to end-users.

Note that CircuitOptions.DetailedErrors is available in Blazor Server, but not in Blazor WebAssembly.
