The assembly does not have a version number.

The identity of an assembly is composed of the following information:

• Assembly name

• Version number

• Culture

• Public key (for strong-named assemblies).

The .NET Framework uses the version number to uniquely identify an assembly, and to bind to types in strong-named assemblies. The version number is used together with version and publisher policy. By default, applications run only with the assembly version with which they were built.

To fix a violation of this rule, add a version number to the assembly using the System.Reflection..::.AssemblyVersionAttribute attribute. See the following example.

Do not suppress a warning from this rule for assemblies that are used by third parties, or in a production environment.

The following example shows an assemble with the AssemblyVersionAttribute attribute applied.

Imports System
Imports System.Reflection

<Assembly: AssemblyVersionAttribute("4.3.2.1")>
Namespace DesignLibrary
End Namespace

using System;
using System.Reflection;

[assembly: AssemblyVersionAttribute("4.3.2.1")]
namespace DesignLibrary {}

using namespace System;
using namespace System::Reflection;

[assembly: AssemblyVersionAttribute("4.3.2.1")];
namespace DesignLibrary {}
