Properties

1. Purpose

This module (DataPRO/DASFactory/Properties/AssemblyInfo.cs) is an assembly-level configuration file for the DASFactory .NET assembly. Its purpose is to define metadata attributes that describe the assembly—such as title, product name, version, and COM visibility—without containing any executable logic. It serves as a declarative manifest for build-time and runtime identification and integration, particularly relevant for deployment, versioning, and COM interop scenarios.

2. Public Interface

This file contains no public functions, classes, or methods. It only declares assembly-level attributes via the System.Reflection and System.Runtime.InteropServices namespaces. All declarations are attribute usages on the Assembly object (e.g., [assembly: AssemblyTitle(...)]), which are consumed by the .NET runtime and tooling—not invoked programmatically.

3. Invariants

• The assembly is not visible to COM (ComVisible(false)), meaning it cannot be consumed by COM clients unless explicitly overridden elsewhere (e.g., on specific types).
• The assembly version is fixed at 1.0.0.0 for both AssemblyVersion and AssemblyFileVersion. No wildcard (*) is used for automatic build/revision numbering.
• The Guid attribute is set to "16aa1a8c-fcb8-4e68-b49c-91b5a486d990" for typelib identification if COM exposure were enabled (currently disabled).
• All culture-specific attributes (AssemblyCulture("")) indicate this is a neutral (non-localized) assembly.

4. Dependencies

• Depends on:
  • System.Reflection (for AssemblyTitle, AssemblyDescription, etc.)
  • System.Runtime.InteropServices (for ComVisible, Guid)
• Depends on nothing else (no external project or library references are declared in this file).
• Used by:
  • The .NET build system (to embed metadata into the compiled assembly manifest).
  • Runtime tools (e.g., Assembly.GetName(), reflection APIs, FileVersionInfo).
  • COM interop tools (e.g., tlbexp.exe)—though disabled, the GUID is present for potential future use.

5. Gotchas

• COM visibility is disabled globally, so even if types in this assembly are [ComVisible(true)], they will not be visible to COM unless the assembly-level ComVisible(false) is overridden per-type.
• Version numbers are hardcoded to 1.0.0.0 with no wildcard usage—this may indicate legacy or manual versioning; no automatic build/revision incrementing occurs.
• The AssemblyCulture("") implies a neutral (non-localized) assembly, but if localization were intended, this should contain a culture name (e.g., "en-US").
• The AssemblyConfiguration("") and AssemblyCompany("") fields are empty strings—no build configuration (e.g., "Debug"/"Release") or company name is recorded here.
• No functional code exists in this file; it is purely metadata. Misinterpreting it as containing business logic is a common mistake for new developers.
• None identified from source alone.
