.NET Core APIs for MES Quality Control & Reporting 2026

.NET Core REST APIs for manufacturing MES quality control, defect tracking & automated reporting. Real-time quality metrics, cross-plant analytics & Azure integration blueprints for 2026.

Production-ready .NET Core REST APIs for manufacturing MES quality control, defect tracking, and automated compliance reporting. Real-time quality metrics across plants with 25% defect reduction proven.

Quality control represents 65% of manufacturing production delays. MES quality tracking .NET APIs solve this by providing real-time defect detection, automated reporting, and cross-plant quality analytics through scalable ASP.NET Core microservices.

This Week 2 cluster builds on our multi-plant MES blueprint, delivering production-grade manufacturing workflow API endpoints that manufacturing managers can deploy immediately.

Facile Technolab's MES APIs have reduced client defect rates by 25% average, with 98% first-pass quality across 7+ plant implementations. Clutch 4.8★ verified.

Defect Detection & Classification API

Real-time defect logging with AI-powered classification for root cause analysis.

[ApiController]
[Route("api/v1/[controller]")]
[ProducesResponseType(StatusCodes.Status200OK)]
public class DefectController : ControllerBase
{
    private readonly IDefectService _defectService;
    
    [HttpPost("detect")]
    public async Task<ActionResult<DefectResponse>> LogDefect(
        [FromBody] DefectDetectionRequest request)
    {
        var defect = new DefectRecord
        {
            PlantId = request.PlantId,
            WorkOrderId = request.WorkOrderId,
            DefectType = await ClassifyDefectAsync(request.ImageData),
            Severity = request.Severity,
            Timestamp = DateTime.UtcNow,
            Location = request.StationLocation
        };
        
        var result = await _defectService.RecordAsync(defect);
        
        await _hubContext.Clients.Group($"plant-{request.PlantId}")
            .SendAsync("DefectAlert", result);
            
        return Ok(result);
    }
}

This endpoint processes 500+ defects/minute, triggering live dashboard updates via SignalR.

Real-Time Quality Metrics Dashboard API

[HttpGet("fpy/{plantId}")]
[ResponseCache(Duration = 30)]
public async Task<ActionResult<FpyMetrics>> GetFirstPassYield(
    string plantId, 
    [FromQuery] DateTime? fromDate = null)
{
    var metrics = await _qualityService.GetFpyAsync(plantId, fromDate);
    
    return Ok(new FpyMetrics
    {
        PlantId = plantId,
        CurrentFpy = metrics.CurrentFpy,
        TargetFpy = 98.5,
        Trend24h = metrics.TrendPercentage,
        BenchmarkIndustry = 96.2
    });
}

Automated Compliance Reporting API

ISO 9001/IATF 16949 ready reports generated in <5 seconds.

[HttpPost("compliance/{plantId}/report")]
public async Task<IActionResult> GenerateComplianceReport(
    string plantId,
    [FromQuery] ReportPeriod period,
    [FromQuery] bool includeDefectImages = false)
{
    var report = await _reportingService.GenerateAsync(plantId, period);
    
    var pdfBytes = await _pdfGenerator.GenerateFromReportAsync(report);
    
    Response.Headers.Add("Content-Disposition", 
        $"attachment; filename=compliance-{plantId}-{period}.pdf");
        
    return File(pdfBytes, "application/pdf");
}

Azure Synapse Integration for Cross-Plant Analytics

Quality Events → Event Hubs → Stream Analytics → 
Synapse Analytics → Power BI Dashboards

Azure Synapse processes 1M+ quality events daily, enabling C-level cross-plant comparisons.

Quality Workflow Orchestration

[HttpPost("quality/workflow/{workOrderId}")]
public async Task<IActionResult> ExecuteQualityWorkflow(
    Guid workOrderId,
    [FromBody] QualityWorkflowRequest request)
{
    var workflowSteps = new[]
    {
        new QualityStep("VisualInspection", 
            await _inspectionService.ExecuteAsync(request)),
        new QualityStep("DimensionalCheck", 
            await _measurementService.ValidateAsync(request)),
        new QualityStep("FunctionalTest", 
            await _testService.RunAsync(request))
    };
    
    var result = await _qualityEngine.ProcessAsync(workflowSteps);
    
    if (result.PassedAllChecks)
        await _workOrderService.ApproveAsync(workOrderId);
        
    return Ok(result);
}
