BPUAPlatformBootstrapper

Purpose

BPUAPlatformBootstrapper is the class that initializes the BPUA runtime. It is intentionally small, but it performs one of the most important responsibilities in the platform: it assembles the runtime prerequisites in the correct order.

Main Public Entry Point

The class exposes a single public method:

public void BootBPUAPlatform(string pathToFolderWithExecutableFile, bool isDevelopmentEnvironment)

This method accepts the host path and the environment mode and then executes the full boot sequence.

Current Internal Sequence

In the current code base, the method calls the following internal steps:

InitializeComponent
LoadApplicationConfiguration
CalculatePathToFolderWithDynamicAssemblies
LoadStaticAssemblies
LoadDynamicAssemblies
InitializeApplication
InitializeUseCaseActivator
ReleaseResources

Static Assemblies Loaded by the Bootstrapper

The bootstrapper currently adds the assemblies of the built-in Business Logic, Data Processing Logic, Data Access Logic, and Orchestration projects to the list of loaded assemblies. This gives the boot pipeline a baseline set of platform assemblies before any business-specific plugin assemblies are scanned.

UseCaseActivator Registration

After application initialization, the bootstrapper creates a UseCaseActivator, transfers the currently known assembly processors and loaded assemblies into it, and registers it in the service registry under the key IUseCaseActivator.

This is a key design point: initial boot makes on-demand activation part of the runtime itself.

Why This Class Should Remain Small

The bootstrapper should orchestrate boot, not become the owner of every boot detail. Path calculation belongs to configuration helpers. Assembly loading belongs to dedicated loaders and processors. Registration rules belong to registrars and scanners.

The current implementation already reflects that direction: the bootstrapper coordinates the process rather than implementing the low-level details itself.

Summary

BPUAPlatformBootstrapper is the runtime assembly point of the platform. It prepares configuration, discovers the initial assemblies, initializes the application singleton, and ensures that future use cases can be activated without static coupling to the host.
