TargetFrameworkAttribute Class

Definition

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

public ref class TargetFrameworkAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Assembly, AllowMultiple=false, Inherited=false)]
public sealed class TargetFrameworkAttribute : Attribute
[<System.AttributeUsage(System.AttributeTargets.Assembly, AllowMultiple=false, Inherited=false)>]
type TargetFrameworkAttribute = class
    inherit Attribute
Public NotInheritable Class TargetFrameworkAttribute

Remarks

The TargetFrameworkAttribute class provides an attribute that you can apply to an assembly to indicate the version of the .NET 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 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 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

Constructors

TargetFrameworkAttribute(String)

Initializes an instance of the TargetFrameworkAttribute class by specifying the .NET version against which an assembly was built.

Properties

FrameworkDisplayName

Gets the display name of the .NET version against which an assembly was built.

FrameworkName

Gets the name of the .NET version against which a particular assembly was compiled.

TypeId

When implemented in a derived class, gets a unique identifier for this Attribute.

Methods

Equals(Object)

Returns a value that indicates whether this instance is equal to a specified object.

(Inherited from Attribute)
GetHashCode()

Returns the hash code for this instance.

(Inherited from Attribute)
GetType()

Gets the Type of the current instance.

(Inherited from Object)
IsDefaultAttribute()

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

(Inherited from Attribute)
Match(Object)

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

(Inherited from Attribute)

Explicit Interface Implementations

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.

(Inherited from Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.

(Inherited from Attribute)
_Attribute.GetTypeInfoCount(UInt32)
