This project provides standardized components for coding processes in PowerApps plugins and Azure functions.
A key design principle of this project is extensibility through architectural standardization. It should be easy to modify or enhance processes that use the various components created in this project without having to make large scale code changes. To that end, the code for this project adheres to the concepts of coding to an interface and inversion of control.
If the implementation for a class doesn't meet your needs, you can change it either through inheritance and overrides, or by writing a completely different implementation for the defined interface. Either way, register your new implementation in the process IoC container and your done.
This project is segregated into various solutions that consist of one or more Shared Projects that can be consumed in any C# project based that supports the Shared Project model. Each shared project has a corresponding .NET Framework Library project that creates the associated assemblies.
The CCLLC.Telementry solutions provides the components needed to capture telemetry information for logging in an external system. It is a sandbox-safe implementation of a subset of the Microsoft\Applicationinsights-dotnet Sdk]. It is fully compatible with Application Insights, but can also be extended to connect to custom telemetry system endpoints with alternate telemetry serialization schemes.
The CCLLC.Core solution provides the following solution components. Each component is based on defined interfaces and at least one optional implementation that can be modified through inheritance:
-
CCLLC.Core.IocContainer : A lightweight inversion of control container implementation that is used within process to inject dependencies. Using a container simplifies maintenance and extensibility of any created processes.
-
CCLLC.Core.Encryption: A simple SHA256 encryption implementation.
-
CCLLC.Core.Net: A simplified implementation for building HTTP web requests. This module provides an interface and implementation that wraps the System.Net HttpWebRequest which results in code that can be unit tested because the web request execution process can be mocked.
-
CCLLC.Core.Net.Instrumented: An enhanced implementation for making HTTP web requests that includes dependency telemetry capture.
-
CCLLC.Core.Serialization: A standardized implementation for serializing objects to JSON or XML. The default implementations are based on System.Net DataContracts.
-
CCLLC.Core.RestClient: A standardized implementation for using POCO objects to interact with REST based web services.
-
CCLLC.Core.ProcessModel : A standardized, data agnostic, execution context model for creating processes independently of the platform that will ultimately host the process. Building to this model makes it easy to move business logic between different process implementation platforms (e.g. CDS plugin or Azure Function) it also simplifies changes related to data schema.
The CCLLC.CDS solution provides the following components that provide Power Apps/Common Data Service platform specific implementations of the CCLLC.Core.ProcessModel and related extensions.
-
CCLLC.CDS.Sdk : Provides a standardized plugin development framework implementation based on CCLLC.Core interfaces. This allows any process created against the CCLLC.Core.Process model to operate as a CDS plugin component.
-
CCLLC.CDS.Sdk.Data : Provides data access helpers including a Fluent Query Expression Builder and various IOrganizationService extensions to retrieve data.
-
CCLLC.CDS.Sdk.Instrumented: Extends the CCLLC.CDS.Sdk plugin framework with telemetry data capture.
-
CCLLC.CDS.Sdk.SearchUtilities: Extends the CCLLC.CDS.Sdk framework with a standard mechanism to implement entity searches that include results from matching related entity searches. For example a search on part number returns parts with that part number and parts linked to alternate part number records with a matching part number.
In addition to simply downloading and consuming the Shared Projects, each project is also being distributed through Nuget as either an assembly and as a source package using the project name (e.g. CCLLC.Core.Encryption) for assembly distribution and project name with .Sources suffix (e.g. CCLLC.Core.Encryption.Sources) for source code.
All source code packages are installed as folders under the projects App_Packages folder._
