QueryGuard.AspNetCore

Opens a QueryGuard.NET session around each ASP.NET Core request, so repeated EF Core queries can be grouped per endpoint and query budgets evaluated per route.

Quickstart

builder.Services.AddQueryGuard(options =>
{
    // Recommended for the first preview: development and test environments.
    options.Enabled = builder.Environment.IsDevelopment();

    options.DefaultPolicy = QueryGuardPolicy.Create("default")
        .WithMaxQueries(20, QueryGuardSeverity.Warning)
        .WithMaxOccurrencesPerFingerprint(5, QueryGuardSeverity.Failure);
});

builder.Services.AddDbContext<AppDbContext>((services, db) =>
{
    db.UseSqlite(connectionString);
    db.AddInterceptors(services.GetRequiredService<QueryGuardCommandInterceptor>());
});

var app = builder.Build();

app.UseRouting();

// After UseRouting, so a scope is named by its matched route pattern rather than its URL. Earlier and
// every request lands in one "(unmatched)" scope: QueryGuard still works, the reports just lose the
// one label that makes them useful.
app.UseQueryGuard();

The middleware observes and nothing else

It does not write to the response body, add headers, or throw on the request path. The response your application produces and the exception it raises are exactly what a client sees, with QueryGuard enabled or disabled. Findings go to ILogger with stable event IDs.

That is a deliberate constraint, not a missing feature: see ADR-0006.

Policies are per route pattern

A policy is selected by the endpoint's route pattern, so /api/companies/1 and /api/companies/2 share the policy for GET /api/companies/{id} rather than creating one per identifier.

options.ForEndpoint("GET /api/reports/{id}", policy => policy
    .WithMaxQueries(40)
    .AllowFingerprint("QG-FP-1A2B3C4D", reason: "Bounded provider lookup; at most three sections."));
