Returns the hash code for this instance.(Inherited from Attribute.)
When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)
When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)
Returns a string that represents the current object.(Inherited from Object.)

Theclass has been deprecated in the .NET Framework version 3.5 Service Pack 1 (SP1) and later versions.
A frozen string is a string literal object that is compatible with the managed heap and has been serialized into a native image by the Ngen.exe (Native Image Generator). The attribute allows you to optimize your code by pre-allocating string literals during native image generation rather than at run time. After a string literal has been frozen, code can simply refer to the string using the address in the native image.
Themust be applied on the assembly level.
Note that the common language runtime (CLR) cannot unload any native image that has a frozen string because any object in the heap might refer to the frozen string. Therefore, you should use theclass only in cases where the native image that contains the frozen string is shared heavily.
The following code example demonstrates how to apply theto an assembly.
