AssemblyMetadata

RSCG – AssemblyMetadata    

Generates compile-time assembly metadata constants (build date, year, time, etc.) — access build info as typed properties without runtime reflection.

How to use

1. Add the package as an Analyzer (no runtime reference needed):

“`xml

<="" privateassets="all" version="2.0.16" include="AssemblyMetadata">

OutputItemType=”Analyzer” ReferenceOutputAssembly=”false” />

“`

2. Use the generated AssemblyMetadataInfo class directly:

“`csharp

Console.WriteLine(BenjaminAbt.AssemblyMetadata.AssemblyMetadataInfo.BuildInfo.BuildDateYear);

“`

You can use for Embedding build date/time metadata into assemblies as compile-time constants — useful for version screens, diagnostics, or ‘built on’ display info without runtime I/O or reflection.

This is how you can use AssemblyMetadata .

The code that you start with is

<project sdk="Microsoft.NET.Sdk">

  <propertygroup>
    <outputtype>Exe</outputtype>
    <targetframework>net10.0</targetframework>
    <implicitusings>enable</implicitusings>
    <nullable>enable</nullable>
  </propertygroup>

  <itemgroup>
    <packagereference version="2.0.16" include="AssemblyMetadata" referenceoutputassembly="false" outputitemtype="Analyzer">
  </packagereference>
	<propertygroup>
		<emitcompilergeneratedfiles>true</emitcompilergeneratedfiles>
		<compilergeneratedfilesoutputpath>$(BaseIntermediateOutputPath)\GX</compilergeneratedfilesoutputpath>
	</propertygroup>
</itemgroup>

The code that you will use is

Console.WriteLine(BenjaminAbt.AssemblyMetadata.AssemblyMetadataInfo.BuildInfo.BuildDateYear);

   The code that is generated is

// <auto-generated>
namespace BenjaminAbt.AssemblyMetadata
{
    internal static class AssemblyMetadataInfo
    {
        /// <summary>Contains compile-time build metadata constants.</summary>
        internal static class BuildInfo

            public const string BuildTimestamp = "2026-04-03T05:50:57.6130105+00:00";

            /// <summary>Build time as Windows FileTime (100-ns intervals since 1601-01-01 UTC).</summary>

            /// <summary>Year component of the build date (UTC).</summary>
            public const int BuildDateYear = 2026;

            /// <summary>Month component of the build date (UTC).</summary>
            public const int BuildDateMonth = 4;

            /// <summary>Day component of the build date (UTC).</summary>
            public const int BuildDateDay = 3;

            /// <summary>Hour component of the build time (UTC, 24-hour).</summary>
            public const int BuildTimeHour = 5;

            /// <summary>Minute component of the build time (UTC).</summary>
            public const int BuildTimeMinute = 50;

            /// <summary>Second component of the build time (UTC).</summary>
            public const int BuildTimeSecond = 57;
        }
    }
