[MartinCarpentier]

Bug Report

• Grafana.OpenTelemetry 0.8.1-beta

• net8.0 with asp.net

Symptom

When adding UseGrafana on the OpenTelemetry providers on trimmed or native aot compiled applications, the app fails during startup with the following exception.

2024-05-12 17:02:06 Unhandled Exception: System.InvalidOperationException: Reflection-based serialization has been disabled for this application. Either use the source generator APIs or explicitly configure the 'JsonSerializerOptions.TypeInfoResolver' property.

.AddService(serviceName))
.UseGrafana(config =>
{
config.ServiceName = serviceName;
});
});
builder.Services.AddOpenTelemetry()
.ConfigureResource(resource => resource.AddService(serviceName))
.WithTracing(tracing => tracing
.AddAspNetCoreInstrumentation()
.UseGrafana(config =>
{
config.ServiceName = serviceName;
}))
.WithMetrics(metrics => metrics
.AddAspNetCoreInstrumentation()
.AddRuntimeInstrumentation()
.AddProcessInstrumentation()
.UseGrafana(config =>
{
