public sealed class TargetFrameworkAttribute : Attribute

NameDescription
System_CAPS_pubmethodTargetFrameworkAttribute(String)

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

NameDescription
System_CAPS_pubpropertyFrameworkDisplayName

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

System_CAPS_pubpropertyFrameworkName

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

System_CAPS_pubpropertyTypeId

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

NameDescription
System_CAPS_pubmethodEquals(Object)

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)

System_CAPS_pubmethodGetHashCode()

Returns the hash code for this instance.(Inherited from Attribute.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodIsDefaultAttribute()

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)

System_CAPS_pubmethodMatch(Object)

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_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.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfoCount(UInt32)

Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

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.
   }
}

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.
   }
}
