I am trying to setup honeycomb in my .net sample app with .net 6.
https://docs.honeycomb.io/getting-data-in/opentelemetry/dotnet-distro/#initialize
I am getting an error when I run my code with the below exception:
System.MissingMethodException: 'Method not found: 'OpenTelemetry.Trace.TracerProviderBuilder OpenTelemetry.Trace.TracerProviderBuilderExtensions.ConfigureBuilder(OpenTelemetry.Trace.TracerProviderBuilder, System.Action`2<System.IServiceProvider,OpenTelemetry.Trace.TracerProviderBuilder>)'.'
Below is my program.cs file
using Microsoft.EntityFrameworkCore;
using ProductCRUDAPI.Models;
using OpenTelemetry.Trace;
using OpenTelemetry;
using Honeycomb.OpenTelemetry;
var builder = WebApplication.CreateBuilder(args);
var connectionString = builder.Configuration.GetConnectionString("DB");
builder.Services.AddDbContextPool<DbContext>(option => option.UseSqlServer(connectionString));
// Add services to the container.
var honeycombOptions = builder.Configuration.GetHoneycombOptions();
builder.Services.AddControllers();
builder.Services.AddOpenTelemetry().WithTracing(configure: otelBuilder =>
otelBuilder
.AddHoneycomb(honeycombOptions)
.AddAspNetCoreInstrumentationWithBaggage()
).StartWithHost();
builder.Services.AddSingleton(TracerProvider.Default.GetTracer(honeycombOptions.ServiceName));
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
var app = builder.Build();
// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
app.UseSwagger();
app.UseSwaggerUI();
}
app.UseAuthorization();
app.MapControllers();
app.Run();
I am trying to setup honeycomb in my .net sample app for testing using the below guide
https://docs.honeycomb.io/getting-data-in/opentelemetry/dotnet-distro/#initialize
Was expecting to get the connection to go through and the logger to initialize successfully so I can attach it to my endpoints.
Just experienced this error myself, there's a package missing, go to the NUGet Package Manager in Visual Studio, checked the "include prerelease" box and then install the
OpenTelemetry.Instrumentation.AspNetCore
prerelease package.
Honeycomb have fairly recently upgraded their OpenTelemetry package from prerelease, but it seems some other dependencies are required from OpenTelemetry packages still in prerelease, some issues like these may keep occurring until all the dependent packages are out of prerelease and development stabilises a bit!

I am attempting to setup a simple solution that consists of a ASP.NET Core 6 Web Api project and a .NET Core class library project using EF Core 7 and running into problems setting up the DBContext in the Program.cs file and running EF migrations.
Here is a copy of my Program.cs
using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.EntityFrameworkCore;
using Microsoft.Identity.Web;
using MyEFCoreTestProject.EntityFrameworkCore;
var builder = WebApplication.CreateBuilder(args);
// Add services to the container.
builder.Services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddMicrosoftIdentityWebApi(builder.Configuration.GetSection("AzureAd"));
builder.Services.AddControllers();
builder.Services.AddDbContext<MyDbContext>(
options => options.UseSqlServer(builder.Configuration.GetConnectionString("DefaultConnection")));
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
var app = builder.Build();
// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
app.UseSwagger();
app.UseSwaggerUI();
}
app.UseHttpsRedirection();
app.UseAuthentication();
app.UseAuthorization();
app.MapControllers();
app.Run();
Here is a copy of my DBContext in the other project.
using Core;
using Microsoft.EntityFrameworkCore;
public class MyDbContext : DbContext
{
public MyDbContext(DbContextOptions<MyDbContext> options)
: base(options)
{
}
public DbSet<Customer> Customers{ get; set; }
public DbSet<CustomerAddress> CustomerAddresses { get; set; }
}
In my class library project where the DBContext exists I have the following nuget packages installed:
Microsoft.EntityFrameworkCore 7.0.2
Microsoft.EntityFrameworkCore.Design 7.0.2
Microsoft.EntityFrameworkCore.Relational 7.0.2
Microsoft.EntityFrameworkCore.SqlServer 7.0.2
Microsoft.EntityFrameworkCore.Tools 7.0.2
No matter how I attempt to run the migration I get the following error:
Microsoft.EntityFrameworkCore.Design.OperationException: Unable to create an object of type 'MyDbContext'. For the different patterns supported at design time, see https://go.microsoft.com/fwlink/?linkid=851728
---> System.InvalidOperationException: Unable to resolve service for type 'Microsoft.EntityFrameworkCore.DbContextOptions`1[MyEFCoreTestProject.MyDbContext]' while attempting to activate 'MyEFCoreTestProject.MyDbContext'.
This is just what I have been running into while trying to do what I believe is a simple dependency registration. What I really would like to do is create a DbContext with a constructor that allows me to pass the connection string and some other flags in as parameters but my first step is just to get things working so I will have to tackle that next after this issue is solved.
Also I am not opposed to a DbContextFactory but I have been unable to find a working example that I could follow in .Net Core 6.
Any help anyone could provide is greatly appreciated.
I have a Blazor server app that is built on .NET Core 3.1. The app is working without problem.
After I updated from VS 2019 to VS 2022 and also .NetCore3.1 to Net6.0 I noticed that my scoped services are not running any more. I have read that the registration of the services are a little bit different in .NET6.0, but I couldn't make it working.
My actual registration is in Startup.cs (that is merged with Program.cs in .NET6.0 as I understood)
public void ConfigureServices(IServiceCollection services)
{
services.AddRazorPages();
services.AddServerSideBlazor();
services.AddScoped<ConnectService>();
services.AddScoped<TagService>();
}
I tried to register in Pogram.cs like below but didn't work
public static void Main(string[] args)
{
CreateHostBuilder(args).Build().Run();
var builder = WebApplication.CreateBuilder(args);
builder.Services.AddRazorPages();
builder.Services.AddServerSideBlazor();
builder.Services.AddScoped<ConnectService>();
builder.Services.AddScoped<TagService>();
}
I am injecting the service in my razor page as follows (that I haven't changed)
#page "/connect2"
#inject TagService TagService
You can get the basic structure with the templated solution.
dotnet new blazorserver -o <OutputDirectory>
It should look something like this
//declare web
var builder = WebApplication.CreateDefault(args)
//add services
builder.Services.AddRazorPages();
builder.Services.AddServerSideBlazor();
builder.Services.AddScoped<ConnectService>();
builder.Services.AddScoped<TagService>();
//then build app
var app = builder.Build();
//add any neccessary routing middleware
//then run
app.Run()
I used to use .NET core 5, but now I'm trying to use .NET core 6, it seems the old Startup.cs is mixed now with Program.cs.
The thing is that I'm trying to add log4net to my project, and it gives me an error I'm not sure what is happening or I'm missing something. The error says:
Severity Code Description Project File Line Suppression State
Error CS1061 'ILoggingBuilder' does not contain a definition for 'AddLog4Net' and no accessible extension method 'AddLog4Net' accepting a first argument of type 'ILoggingBuilder' could be found
I have installed log4net via Nuget Managment and Package Manager Console Nothing seems to work, here is a part of my Program.cs file:
var builder = WebApplication.CreateBuilder(args);
builder.Logging.AddLog4Net(); // <-- here is where I got the error
// Add services to the container.
var services = builder.Services;
services.AddCors();
services.AddControllers();
services.AddEndpointsApiExplorer();
services.AddSwaggerGen();
services.AddLogging();
You need a separate extension package to make it work in most use cases.
The package you need is:
https://www.nuget.org/packages/Microsoft.Extensions.Logging.Log4Net.AspNetCore/
Documentation and source:
https://github.com/huorswords/Microsoft.Extensions.Logging.Log4Net.AspNetCore
You can use similar like below:
builder.Host.ConfigureLogging(logging =>
{
logging.AddLog4Net(log4NetConfigFile: "log4net.config");
logging.ClearProviders();
logging.AddConsole();//for Logging on Console
logging.AddLog4Net();//for DB Query Logging
});
I am working the Microsoft Learn tutorials to "Create a web API with ASP.Net Core".
I used .NET5
I have a problem when I run the command:
httprepl connect http://localhost:5000
I am getting a response, "Unable to find an OpenAPI description".
And the following command "ls" returns me from it not trooping endpoints.
c:/xxx/Source/Repos/ContosoPizza
$ httprepl http://localhost:5000
(Disconnected)> connect http://localhost:5000
Using a base address of http://localhost:5000/
Unable to find an OpenAPI description
For detailed tool info, see https://aka.ms/http-repl-doc
http://localhost:5000/> ls
No directory structure has been set, so there is nothing to list. Use the "connect" command to set a directory structure based on an OpenAPI description.
I tried all the solutions offered by #Gowiser in the question launched by #Nuse Why is HttpRepl unable to find an OpenAPI description? The command "ls" does not show available endpoints
But nothing worked.
Working through Create a web API with ASP.NET Core Controllers i also did run into the error
Unable to find an OpenAPI description
The tutorial uses dotnet 6, i was using dotnet core 3.1.
I did the changes from sasha answers here and had to add these packages
dotnet add package Microsoft.OpenApi --version 1.2.3
dotnet add package Swashbuckle.AspNetCore.Swagger --version 6.2.3
dotnet add package Swashbuckle.AspNetCore.SwaggerUI --version 6.2.3
dotnet add package Swashbuckle.AspNetCore.SwaggerGen --version 6.2.3
After all that i still got error messages. In step 4 of Exercise - Create a web API project the following is written
Connect to our web API by running the following command:
httprepl https://localhost:{PORT}
Alternatively, run the following command at any time while the HttpRepl is running:
(Disconnected)> connect https://localhost:{PORT}
I was not aware that running httprepl like this
httprepl https://localhost:{PORT}
still requires that your web app is running. So you have to open a second terminal (cmd.exe) to run your webapi project dotnet run. After that you can connect to the swagger docs using httprepl like this
connect http://localhost:5000 --verbose --openapi /swagger/v1/swagger.json
http://localhost:5000/> ls
. []
WeatherForecast [GET]
http://localhost:5000/> cd WeatherForecast
/WeatherForecast [GET]
http://localhost:5000/WeatherForecast> get
HTTP/1.1 200 OK
This did the trick for me.
Adding the swagger ui
Swashbuckle.AspNetCore - Getting Started contains
Optionally, insert the swagger-ui middleware if you want to expose
interactive documentation, specifying the Swagger JSON endpoint(s) to
power it from.
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("v1/swagger.json", "My API V1");
});
If you change startup.cs to include this
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseSwagger();
app.UseSwaggerUI(c =>
c.SwaggerEndpoint("/swagger/v1/swagger.json", "ContosoPizza v1"));
}
....
You get a nice gui under http://localhost:5000/swagger/ which looks like this
I am assuming you are following the steps described in the 'Create a web API project' exercise of the Create a web API with ASP.NET Core course.
Before going through step 5. make sure in your project there is:
a services.AddSwaggerGen() call in the Startup.ConfigureServices() method
an app.UseSwagger() call in the Startup.Configure() method
Here is a working version of Startup.cs:
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Microsoft.OpenApi.Models;
namespace ContosoPizza
{
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.AddControllers();
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new OpenApiInfo { Title = "ContosoPizza", Version = "v1" });
});
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseSwagger();
app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "ContosoPizza v1"));
}
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
}
}
}
Calling ls in the httprepl session shows expected results:
❯ httprepl http://localhost:5000
(Disconnected)> connect http://localhost:5000
Using a base address of http://localhost:5000/
Using OpenAPI description at http://localhost:5000/swagger/v1/swagger.json
For detailed tool info, see https://aka.ms/http-repl-doc
http://localhost:5000/> ls
. []
WeatherForecast [GET]
http://localhost:5000/>
Here you can find a full project for this exercise.
Indeed #surfmuggle to connect to the API via httprepl, the API had to be running in another terminal, so 2 terminals in total:
1 to run the API with dotnet run
1 other to call instructions like ls or other later
run this command first:
dotnet dev-certs https --trust
I am trying to make a .NET core Web app When I build the solution I get this following error help me out.my
It also shows an error about the Package compatibility
all this happened after I updated my library
I tried to change version number in my csproj file but
It creates more error
