程序.cs

builder.Services.AddOpenTelemetryMetrics(b =>
{
    b.AddPrometheusExporter();
    b.AddMeter(TelemetryConstants.MyAppSource);
    b.SetResourceBuilder(resource);
    b.AddHttpClientInstrumentation();
    b.AddAspNetCoreInstrumentation();
});

当我运行应用程序时，它给出以下错误
System.TypeLoadException: 'Could not load type 'System.ServiceProviderExtensions' from assembly 'OpenTelemetry, Version=1.0.0.0, Culture=neutral, PublicKeyToken=7bd6737fe5b67e3c'.'
位于app.UseOpenTelemetryPrometheusScrapingEndpoint();
