TargetFrameworkAttribute TargetFrameworkAttribute TargetFrameworkAttribute TargetFrameworkAttribute Class

Definition

Identifies the version of the .NET Framework that a particular assembly was compiled against.

Remarks

The TargetFrameworkAttribute class provides an attribute that you can apply to an assembly to indicate the version of the .NET Framework runtime against which the assembly was built. For example, the following example applies the TargetFrameworkAttribute to an assembly to indicate that it was built using .NET Framework 4.

using System;
using System.Runtime.Versioning;

[assembly:TargetFramework(".NETFramework,Version=v4.0")]

namespace MyCompany.Utilities
{
   public class StringLibrary
   {
      // Members defined here.
   }
}
Imports System.Runtime.Versioning

<Assembly:TargetFramework(".NETFramework,Version=v4.0)")>

Namespace MyCompany.Utilities
   Public Class StringLibrary
      ' Members defined here.
   End Class
End Namespace

The TargetFrameworkAttribute class constructor has a single parameter, frameworkName, that specifies the .NET Framework version against which the assembly was built. This parameter maps to the FrameworkName property. In addition, the TargetFrameworkAttribute attribute can specify a FrameworkDisplayName property to provide a more descriptive .NET Framework version string that is suitable for displaying to clients of the assembly. The following example applies the TargetFrameworkAttribute to an assembly and assigns both property values to indicate that the assembly was built using .NET Framework 4.

using System;
using System.Runtime.Versioning;

[assembly:TargetFramework(".NETFramework,Version=v4.0", 
          FrameworkDisplayName = ".NET Framework, Version 4.0")]

namespace MyCompany.Utilities
{
   public class StringLibrary
   {
      // Members defined here.
   }
}
Imports System.Runtime.Versioning

<Assembly:TargetFramework(".NETFramework,Version=v4.0)", _
          FrameworkDisplayName := ".NET Framework, Version 4.0")>

Namespace MyCompany.Utilities
   Public Class StringLibrary
      ' Members defined here.
   End Class
End Namespace
