Grouping adjacent XYZ points, no idea how to go about this

Let's assume I have an array of point: 0,0,0 0,0,1 0,1,0 1,0,0 2,2,2 5,5,5 5,5,6 Both groups of points should result in 1 XYZ coordinates each, I can't figure out for my life how to do this. (No Screenshots as I have nothing)

MVC App's Post request not reaching

First off, yes I already asked this last friday but couldn't follow trough due to not having the source code for the weekend. Either way, here's my problem: I have an MVC Web Api in .NET 8.0, all Get requests from all controllers work as intended, but for Post requests on the other hand, they all return an HTTP Error 405 (Method not Allowed). Here is my initialization class and one of my Post method (they are all basiaclly structured the same) (Also, all the Cors stuff are things I already tried with no avail) Initialization Class:

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddDbContext<SkyblockRessourcesAPIContext>(options =>
    options.UseSqlServer(builder.Configuration.GetConnectionString("SkyblockRessourcesAPIContext") ?? throw new InvalidOperationException("Connection string 'SkyblockRessourcesAPIContext' not found."), x => x.UseNetTopologySuite()));

// Add services to the container.
builder.Services.AddControllersWithViews();

builder.Services.AddCors(o => o.AddDefaultPolicy(builder =>
{
    builder.AllowAnyOrigin().AllowAnyHeader().AllowAnyMethod();
}));

var app = builder.Build();

app.UseCors(builder =>
{
    builder.AllowAnyOrigin().AllowAnyHeader().AllowAnyMethod();
});

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Home/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

app.UseHttpsRedirection();
app.UseStaticFiles();

app.UseRouting();

app.UseAuthorization();

app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}");

app.Run();

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddDbContext<SkyblockRessourcesAPIContext>(options =>
    options.UseSqlServer(builder.Configuration.GetConnectionString("SkyblockRessourcesAPIContext") ?? throw new InvalidOperationException("Connection string 'SkyblockRessourcesAPIContext' not found."), x => x.UseNetTopologySuite()));

// Add services to the container.
builder.Services.AddControllersWithViews();

builder.Services.AddCors(o => o.AddDefaultPolicy(builder =>
{
    builder.AllowAnyOrigin().AllowAnyHeader().AllowAnyMethod();
}));

var app = builder.Build();

app.UseCors(builder =>
{
    builder.AllowAnyOrigin().AllowAnyHeader().AllowAnyMethod();
});

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Home/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

app.UseHttpsRedirection();
app.UseStaticFiles();

app.UseRouting();

app.UseAuthorization();

app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}");

app.Run();

Controller Example:

❔ Visual Studio Build doesn't run on other computer

So I made a Visual Studio program for a client that has a bunch of dll when built, however, when i sent it to the client, they get an error saying "System.AggregateException: One or more errors occurred. (Response status code does not indicate success: 422 ().)" x30 times. From what I can see it's because the program sill uses my local files Ex:"C:/Users/aruest/..." even on their computer when they're connected on another user. Any fixes?
