Looking for a logging solution

Working on ASP.NET program.
I have a lot of stuff i want to do for logging. First off i want to log every time an endpoint is accessed, who accessed it, when it was accessed what info was passed to the api and the datatype that the endpoint returned. Then there's all the stuff i see in the command line. i would also like to log this stuff. finally i want to be able to query some kind of database of the logs to get data about what's going on, so ideally logs have types and all that jazz. Anyone know any pre existing solutions for this?

ASP.NET endpoint logging

I am building an ASP.NET api. I want to log info about who is accessing my API and how. I want to log the IP address of the user, the end point they called and the parameters they passed ind and the current time. I've done some research on this already and found Serilog, adding it to my middleware

PathString endpoint = ctx.Request.Path;
string? ipAddress = ctx.Connection.RemoteIpAddress?.ToString();
string? currentTime = DateTimeOffset.Now.ToString("yyyy-MM-dd HH:mm:ss.fff zzz");
string requestData = await GetRequestBodyAsync(ctx.Request);

// Log to the endpoint-specific file
Log.Logger.ForContext("SourceContext", "API_Endpoints")
    .Information("{Time}: IP: {IP}, Endpoint: {Endpoint}, Data: {Data}",
        currentTime, ipAddress, endpoint, requestData);

PathString endpoint = ctx.Request.Path;
string? ipAddress = ctx.Connection.RemoteIpAddress?.ToString();
string? currentTime = DateTimeOffset.Now.ToString("yyyy-MM-dd HH:mm:ss.fff zzz");
string requestData = await GetRequestBodyAsync(ctx.Request);

// Log to the endpoint-specific file
Log.Logger.ForContext("SourceContext", "API_Endpoints")
    .Information("{Time}: IP: {IP}, Endpoint: {Endpoint}, Data: {Data}",
        currentTime, ipAddress, endpoint, requestData);

But this logs everything, I need to log less. For one thing, one of my endpoints is a login and i don't want to store passwords in the logs. For another this system logs stuff that isn't and API calls. here's a snippet of what it captures:

✅ IIS?

Soooo.. i tried to run my ASP.NET project and rider threw an error i had never seen before. It said i had to set up IIS. i though what the heck, you didn't need this 20 min ago. but I clicked the link to the settings and followed the instructions. I think i installed iis, then i wanted me to install ASP.NET Core module. I clicked the doc page and, found the Microsoft link for the install, rebooted and i am done. but i am not. still doesn't work. While rider filled in the IIS express root folder on its own it did not fill in the ASP.NET core module file location. 1) what on earth is IIS? 2) why didn't i need it 20 min ago? only major change i made to the code was adding a hosted service 3) Where is the file location for ASP.NET Core module? (going to sleep, then oral surgery, then more sleep, so i am going to be delayed getting back to this.)

✅ using using to clear up ambiguous references.

I've to two method called index: Microsoft.EntityFrameworkCore.Index System.ComponentModel.DataAnnotations.Schema.Index i don't use the 2nd one. I want every mention of index to be interpreted as the first one. I've tried adding one of these using's to fix the problem, but nether works, it just says it Cannot resolve symbol 'Index'

using Index = Microsoft.EntityFrameworkCore.Index;
using IndexCB = System.ComponentModel.DataAnnotations.Schema.Index;

Trying to scaffold a MySQL database with Rider

I am trying to scaffold a MySQL database. I am using Rider. I found this article on the MySQL website: https://dev.mysql.com/doc/connector-net/en/connector-net-entityframework-core-scaffold-example.html but the commands it uses seems to require Visual Studio which i am not using. then i found this article from Jetbrains themselves: https://blog.jetbrains.com/dotnet/2022/01/31/entity-framework-core-inside-rider-ui-way/#alternatives

Temporary Pause

I am using .NET 8 I've got an ASP.NET API that i would like to pause. The goal of this is to prevent any endpoints from being called for a short amount of time. I could do this procedurally with a constant variable that's checked, but I would rather not send nothing. Is there some kind of HTML code i could return that would indicate that the API is offline but like on purpose? Instead of just returning nothing. I also need a way to return this response to the user when they try to access the API while its paused. Is there a way for be to disable all the endpoints and run a default endpoint?

✅ Windows Audio Capture

Building an XAML application. The eventual goal is to capture an audio source and stream it to another application using webhooks. This is my first time doing: 1) XAML 2) Audio anything 3) Webhooks i detect audio sources with this method:

private void PopulateMicrophones() {
    List<String> waveInDevices = Enumerable.Range(0, WaveIn.DeviceCount)
        .Select(i => WaveIn.GetCapabilities(i).ProductName)
        .ToList();
    
    waveInDevices.Insert(0, "Select Mic");

    MicrophoneDropdown.ItemsSource = waveInDevices;
    if (waveInDevices.Count > 0)
    {
        MicrophoneDropdown.SelectedIndex = 0; // Set the first microphone as default selected
    }
}

private void PopulateMicrophones() {
    List<String> waveInDevices = Enumerable.Range(0, WaveIn.DeviceCount)
        .Select(i => WaveIn.GetCapabilities(i).ProductName)
        .ToList();
    
    waveInDevices.Insert(0, "Select Mic");

    MicrophoneDropdown.ItemsSource = waveInDevices;
    if (waveInDevices.Count > 0)
    {
        MicrophoneDropdown.SelectedIndex = 0; // Set the first microphone as default selected
    }
}

Then i use these methods to start and stop recording

private void StartMicrophoneCapture(int deviceNumber) {
    waveIn?.StopRecording();
    waveIn?.Dispose(); // Dispose of the old instance if necessary

    waveIn = new WaveInEvent { DeviceNumber = deviceNumber };

    // Add logging for debugging
    Console.WriteLine($"Starting microphone capture on device {deviceNumber}: {WaveIn.GetCapabilities(deviceNumber).ProductName}");

    waveIn.DataAvailable += OnDataAvailable;
    waveIn.StartRecording();
}

private void StopMicrophoneCapture()
{
    waveIn?.StopRecording();
    waveIn?.Dispose();
    waveIn = null;
    currentVolume = 0; // Reset volume
    VolumeBar.Width = 1; // Reset volume bar width
    VolumeBar.Fill = new SolidColorBrush(Colors.Gray); // Set to neutral color
}

private void StartMicrophoneCapture(int deviceNumber) {
    waveIn?.StopRecording();
    waveIn?.Dispose(); // Dispose of the old instance if necessary

    waveIn = new WaveInEvent { DeviceNumber = deviceNumber };

    // Add logging for debugging
    Console.WriteLine($"Starting microphone capture on device {deviceNumber}: {WaveIn.GetCapabilities(deviceNumber).ProductName}");

    waveIn.DataAvailable += OnDataAvailable;
    waveIn.StartRecording();
}

private void StopMicrophoneCapture()
{
    waveIn?.StopRecording();
    waveIn?.Dispose();
    waveIn = null;
    currentVolume = 0; // Reset volume
    VolumeBar.Width = 1; // Reset volume bar width
    VolumeBar.Fill = new SolidColorBrush(Colors.Gray); // Set to neutral color
}

I added a volume bar so i could see the audio being captured and the audio bar gets set to 0 when i pick an audio source (its one if the mic is null). I think this means i am not capturing audio. but i don't actually know. How do i even debug this?

✅ using

I keep seeing variables defined within a using, like

using(var connection = new SQLiteConnection()){
...

using(var connection = new SQLiteConnection()){
...

what is using? why do people use it? what are the risks of not using it? I think this just disposes of the connection variable (for sure) after its done, but i see it used mostly when dealing with databases. is there a reason for this. If my variables are within a method they get disposed at the end of the method right? How concerned should i be about this?

How does signInManager return tokens?

I am modifying the standard login endpoint provided by MapIdentityApi<IdentityUser>(). at the bottem of the login endpoint: // The signInManager already produced the needed response in the form of a cookie or bearer token. i assume this means that somehow signinManager returns its tokens to the users. I need the login endpoint to return some other data depending on the roles the user has. I've implemented this logic, but i cant figure out how to return the sign tokens as well as my data. it also looks like that even when my users don't have this role the method is not returning tokens, its just returning an empty success. How does signInManager return tokens to the user and how can i get it to return that data to my method so i can control how its returned to the user?

✅ BuildServiceProvider does not exist

private static IServiceProvider _services;
...
IServiceCollection temp = new Microsoft.Extensions.DependencyInjection.ServiceCollection();
_services = temp.BuildServiceProvider();

private static IServiceProvider _services;
...
IServiceCollection temp = new Microsoft.Extensions.DependencyInjection.ServiceCollection();
_services = temp.BuildServiceProvider();

everyone i can find online says this is how to get an instance of IServiceProvider, but it does not work. i found one person with my issue, but they had the wrong useing declaration.

API does not deploy in debug mode

when i try to test my API in debug mode it tries to open the swagger page but i get an unable to connect. the most confusing part is this doesn't happen every time, most of the time i can restart the api (still in debug mode) and it now works, but its getting more and more frequent and i am starting to be concerned.

✅ .NET Identity can't require 2FA

on registration i set up 2fa and require it to log in:

await userManager.SetTwoFactorEnabledAsync(user, true);

 // get the newly defined key
string? key = await userManager.GetAuthenticatorKeyAsync(user);

// make sure we get the key.
if (string.IsNullOrEmpty(key)) {
    await userManager.ResetAuthenticatorKeyAsync(user);
    key = await userManager.GetAuthenticatorKeyAsync(user);

    if (string.IsNullOrEmpty(key)) {
        throw new NotSupportedException("The user manager must produce an authenticator key.");
    }
}

// Return the shared key and indicate successful registration
return TypedResults.Ok(new RegistrationResponse(key));

await userManager.SetTwoFactorEnabledAsync(user, true);

 // get the newly defined key
string? key = await userManager.GetAuthenticatorKeyAsync(user);

// make sure we get the key.
if (string.IsNullOrEmpty(key)) {
    await userManager.ResetAuthenticatorKeyAsync(user);
    key = await userManager.GetAuthenticatorKeyAsync(user);

    if (string.IsNullOrEmpty(key)) {
        throw new NotSupportedException("The user manager must produce an authenticator key.");
    }
}

// Return the shared key and indicate successful registration
return TypedResults.Ok(new RegistrationResponse(key));

however when i go to login:

 var result = await signInManager.PasswordSignInAsync(login.Email, login.Password, isPersistent, lockoutOnFailure: true);
                
if (result.RequiresTwoFactor) {
    if (!string.IsNullOrEmpty(login.TwoFactorCode))
    {
...

 var result = await signInManager.PasswordSignInAsync(login.Email, login.Password, isPersistent, lockoutOnFailure: true);
                
if (result.RequiresTwoFactor) {
    if (!string.IsNullOrEmpty(login.TwoFactorCode))
    {
...

the initial sign in fails (as expected) and result.RequiresTwoFactor is false. what am i doing wrong?
