TargetFrameworkAttribute Class

Definition

Namespace:

System.Runtime.Versioning

Assembly:

System.Runtime.dll

Source:

TargetFrameworkAttribute.cs

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)>]

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. (Inherited from 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)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
