DependencyAttribute Class
Indicates when a dependency is to be loaded by the referring assembly. This class cannot be inherited.
Namespace: System.Runtime.CompilerServices
Assembly: mscorlib (in mscorlib.dll)
The DependencyAttribute type exposes the following members.
| Name | Description | |
|---|---|---|
 | DependencyAttribute | Initializes a new instance of the DependencyAttribute class with the specified LoadHint value. |
| Name | Description | |
|---|---|---|
| Equals | Infrastructure. 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 | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
| _Attribute.GetIDsOfNames | Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.) |
| _Attribute.GetTypeInfo | Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.) |
| _Attribute.GetTypeInfoCount | Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.) |
| _Attribute.Invoke | Provides access to properties and methods exposed by an object. (Inherited from Attribute.) |
This attribute is used by the Ngen.exe (Native Image Generator) to generate native assembly images.
Apply the DependencyAttribute attribute to a dependent assembly with a value of the LoadHint enumeration to specify when a referring assembly is to load a dependency.
A dependency that is likely to be loaded (Always) will cause Ngen.exe to bind to that dependency. Using this hint allows Ngen.exe to generate code that will result in a reduced working set and improved throughput but at the cost of always loading the dependency when the parent assembly is loaded.
The following example specifies that the native image generation service always binds to AssemblyA and sometimes binds to AssemblyB.
using System; using System.Runtime.CompilerServices; [assembly: DependencyAttribute("AssemblyA", LoadHint.Always)] [assembly: DependencyAttribute("AssemblyB", LoadHint.Sometimes)] class Program { static void Main(string[] args) { Console.WriteLine("The DependencyAttribute attribute was applied."); } }
