What does the standard C# file AssemblyInfo.cs primarily contain in a typical project?

Introduction / Context:
Many C# project templates include a file named AssemblyInfo.cs (or equivalent in SDK-style projects via attributes in the .csproj). Understanding its purpose helps you know where common metadata is defined.

Given Data / Assumptions:

• We are using a classic .NET project template with AssemblyInfo.cs present.
• We want to identify the typical content and purpose of this file.

Concept / Approach:
AssemblyInfo.cs contains assembly-level attributes such as AssemblyTitle, AssemblyDescription, AssemblyCompany, AssemblyProduct, AssemblyVersion, and others. These attributes define metadata for the entire assembly and are emitted at the assembly scope.

Step-by-Step Solution:

Verification / Alternative check:
Open a standard .NET Framework project and review AssemblyInfo.cs; the attributes are clearly marked with the assembly: target specifier.

Why Other Options Are Wrong:
Method/class/struct/namespace attributes exist but live in code near those declarations, not in AssemblyInfo.cs by default.

Common Pitfalls:
Assuming AssemblyInfo.cs is mandatory in all templates; SDK-style projects may auto-generate attributes or place them in the .csproj, but they are still assembly-level.

Final Answer:
Assembly-level attributes (e.g., title, version, company)
