Overview

Types are organized by deployment target:

API Models

Database-backed entity models with Entity Framework attributes ([Table], [Key]) for use in API services and data access layers.

Core Entities

using Tyler.Utility.DotNet.Contracts.Types.API;

// Deployed utility registration
var info = new UtilityInfoModel
{
    Utility_Name = "Prod to Test Utility",
    Release_Number = "2026.2.01.02",
    Working_Path = @"C:\NWS Install\Utilities\Prod to Test Utility.exe",
    Update_ID = "46",
    Download_ID = "37"
};

// Configuration settings (encrypted at rest, decrypted at runtime)
var setting = new UtilitySettingsModel
{
    Settings_Id = 1,
    Value = "encrypted-value",
    Type = "awsAccessKeyID",
    Usage = "api"
};

Automation and Scheduling

Models for the task automation pipeline (queue, execute, history):

• AutomationQueueModel - Queued tasks awaiting execution
• AutomationTaskModel - Currently running tasks
• AutomationHistoryModel - Completed task history
• AutomationErrorModel - Task error records
• RecurringProcessModel - CRON-based recurring jobs
• ScheduleQueueModel / ScheduleQueueHistoryModel - Scheduled work items
• ImmediateActionQueueModel / ImmediateActionTaskModel / ImmediateActionHistoryModel - Low-latency (2-second) action pipeline

Database Operations

• DBBackUpSettingsModel - Backup configuration for ESS, GMA, MSP, MDS, CAD, Mobile, RMS, TCM, and Interfaces databases
• DataBaseBackUpHistoryModel - Backup operation history
• DataBaseRestoreHistoryModel - Restore operation history
• ElasticSnapShotSettingModel - Elasticsearch/OpenSearch snapshot settings

Message Queue and Reporting

• TrelloMessageQueueModel - Error/recommendation messages for Trello queue processing
• TrelloMessageQueueResponseModel - Trello card creation responses
• SqsMessageHistory - AWS SQS message history with ML.NET error categorization

Service Infrastructure

• ServiceDiscoveryModel - Service discovery registration
• ServiceServersModel - Server stop/start configuration
• RemoteHostRequestModel / RemoteHostTaskRequestModel / RemoteHostTaskQueueModel - Remote host task execution
• OriFdidCopySettingsModel - ORI/FDID copy operation configuration
• DbFeatures - Feature toggle configuration

IMS Models

Models for the IMS (Infrastructure Management System):

• ImsServer, ImsRealm, ImsPartition - Infrastructure topology
• ImsSoftware, ImsMetaSoftware - Software version management
• ImsTask - Task execution records
• ImsMessage - System messages

Application Lifecycle

• AppHistory / Archived_AppHistory - Application version history
• AppPub / DevAppPub - Published application versions
• AppDocument / AppUpload / DevAppUpload - Application file management
• AppDownloadHistory - Download tracking
• AccessHistoryModel - User access auditing
• ProcessHistoryModel - Process execution timing

Desktop Models

UI binding objects and state containers for WPF/WinForms desktop utilities.

Observable Objects (INotifyPropertyChanged)

Objects that support two-way data binding:

using Tyler.Utility.DotNet.Contracts.Types.Desktop;

// ORI list display
var ori = new OriListViewObj { Prefix = "IL", ORI = "IL1234567" };
ori.PropertyChanged += (s, e) => Console.WriteLine($"{e.PropertyName} changed");

// Service management
var service = new ServiceObj
{
    ServerName = "APP01",
    ServiceName = "NWSService",
    Status = "Running",
    Description = "NWS Application Service"
};

// Process status tracking
var process = new ProcessStatusObj
{
    ProcessName = "Database Restore",
    Status = "In Progress",
    ElapsedTime = "00:05:23"
};

Other observable types: ChildAgencyObj, CurrentBackUpObj, OldBackUpObj, LoggingObj, EzLoggingObj, SqlLoggingObj, RestoreLogObj, SnackBarQueObj, UtilityProgressObj, TrelloErrorReportingObj, ApiHistoryObj, FileStorageObj, ServerObj, SqlScriptObj

Static State Containers

Singleton-pattern objects that hold shared application state:

• BackUpObj - Multi-database backup status tracking (ESS, GMA, MSP, MDS, CAD, Mobile, RMS, TCM, Interfaces)
• DbRestoreUiObj - Database restore operation state (Kibana, SQL AG, restore paths)
• MasterUiObj - Main application state (connections, error reporting, versions)
• DbCredsObj - Secure database credentials (SecureString properties)
• DeployUiObj - Service deployment credentials
• OriFdidCopyUiObject - ORI/FDID copy operation state
• AutomatedErrorObj - Error reporting state
• ManualSubmissionObj - Manual error submission data
• UpdateResult - Update notification state

Configuration and Data Transfer

• ConfigFileObj - Application configuration (server names, auth settings)
• CustomRestoreDbObj / RestoreDbObj - Database restore configuration
• DatabaseVersions - Version migration tracking
• FileStorageSettingsModel - File storage copy configuration
• IncludedTables - Table inclusion for data operations
• SpaceObj - Database space information
• SqlConfiguration - SQL Server configuration with encryption support
• IpInfoObj - IP geolocation data
• ApiObj - Application information DTO
• TrelloErrorDisplayObj - Error display formatting

Services

using Tyler.Utility.DotNet.Contracts.Types.Services;

// Testable time abstraction
public class MyService
{
    private readonly ISystemClock _clock;

    public MyService(ISystemClock clock) => _clock = clock;

    public bool IsBusinessHours() =>
        _clock.Now.Hour >= 8 && _clock.Now.Hour < 17;
}

// Registration
services.AddSingleton<ISystemClock, SystemClock>();

Web

using Tyler.Utility.DotNet.Contracts.Types.Web;

// Azure AD authentication configuration
var auth = new AuthConfig
{
    Instance = "https://login.microsoftonline.com/",
    TenantID = "your-tenant-id",
    ClientID = "your-client-id",
    ClientSecret = "your-client-secret",
    ResourceID = "your-resource-id"
};

Settings (Build-Time Injection)

The Settings namespace contains configuration constants for API, Desktop, and Web contexts. These values are injected from GitHub Secrets at build time via template substitution and are compiled into the DLL.

Consumers access settings through the ApiSettings, GenericAppSettings, or WebSettings static classes:

using Tyler.Utility.DotNet.Contracts.Types.Settings.API;

// Settings are accessed as static properties returning UtilitySettingsModel
UtilitySettingsModel jiraReporter = ApiSettings.JiraSettings3;
UtilitySettingsModel awsKey = ApiSettings.AwsSettings1;

Settings categories:

• API - AWS SQS, Trello, Azure, JIRA configuration
• Desktop - Trello, SQS, and application-specific settings
• Web - Azure AD, Trello, SQS, and blob storage settings

Requirements

• .NET 8.0 or later
• Newtonsoft.Json 13.0.4 - JSON serialization
• System.Text.Json 10.0.2 - JSON serialization
