Application code is always split between many assemblies. In addition to an applications own assembly, all Mono applications reference the mscorlib assembly, which contains the core class libraries of the runtime. An application may use any number of assemblies, some of which may come with the runtime, some of which may be optional runtime components, and others might be written by third party developers. At run time, Mono looks in three places for assemblies necessary to run a program. It first searches the location of the executing assembly. If your application uses assemblies not provided by the runtime, you may place them all in the same directory so that Mono may find them. If a required assembly isnt found there, Mono searches the MONOPATH environment variable. The environment variable should be a colon separated list of paths to search for assemblies. To set this variable in Linux, if you use the bash shell, type export MONOPATHpathtoassemblies anotherpathtoassemblies. Lastly, if an assembly was still not found, Mono searches the the Global Assembly Cache GAC, a repository of shared assemblies. All assemblies provided by Mono are stored in the GAC. The Global Assembly Cache GACThe Global Assembly Cache GAC is a central repository for storing shared assemblies. The GAC allows multiple versions of the same assembly to be installed concurrently and also prevents different assembly vendors from overwriting each others assemblies. The use of the GAC is encouraged for assemblies that will be used by more than one application on the system, and also for assemblies that are expected to be versioned in the future. When an application is launched, Mono extracts the name of the assembly, the version and its public key token and loads the required assembly from the GAC. The GAC is a black boxed repository of assemblies capable of keeping multiple versioncultures of a same assembly. A strongname is considered a unique entry in the GAC i. GAC requires all its assemblies to be strongnamed and signed. Note that the GAC has nothing to do with security In fact assemblies in the GAC arent verified when loaded from the runtime. The GAC is for manageability avoiding DLL hell. GAC Definitions. The GAC is built on the foundation of strongnames. Strongnames can be difficult to understand because they serve a dual purpose manageability and security. Hopefully these definitions can help everyone understand the difference between the two. Strongname. An assembly filename with a version number, a culture and a public key token. As a strongname uniquely identifies an assembly this is the best way to reference them. Strongname Signature. A binary blob inside an assembly that can be verified as the digital signature of the assembly i. Because the the public key inside the assembly is part of the signature it is not possible to modify the assembly contents without detection providing integrity. Strongnamed Assembly. An assembly that has a all the required informations to create a strongname i. Note that this doesnt mean that the assembly is signed See delay signed assemblies. Delay Signed Assembly. An assembly that has a strongname but no strongname signature. While they are a kind of strongnamed assembly the runtime will, by default, refuse to load them as they are unsigned. They are often used in development to keep the private signing key confidential. ECMA Key. The ECMA key isnt a public key or a key at all. It is a special 1. If found the runtime uses its own public key to validate the strongname signature. This hack allows an assembly to reference a standard assembly e. System. dll in a uniform way i. ECMA or anyone else involved in the signing process. Standard ECMA Assembly. Assemblies that are defined in the ECMA standards. They are signed using the ECMA key although other assemblies are also signed with that key, like System. Windows. Forms. SNKStrongname Key file extension. These are files created by the tool sn. They can contains a 1. RSA key pair private and public keys or only the public key. Assembly Names. The Mono Runtime uses the following components to make up unique names for the assemblies The assembly name, the assembly culture, the assembly version, and the assembly public key token. All of those elements are used to make a unique assembly name that can be referenced from the GAC. Assembly Name. The assembly name is the human readable name you give your assembly, and is also the physical name of the assembly minus the extension. You dont need to do anything special to create an assembly name. Its added to the assemblies metadata when the assembly is compiled. Assembly Culture. All assemblies have a culture associated with them. If you do not specify a culture the invariant neutral culture is associated with your assembly. By giving an assembly a culture you can create localized versions of assemblies and install them side by side in the GAC without them interfering with each other. The assembly culture is specified using an assembly attribute assembly Assembly. Culture en CA. Assembly Version. The assembly version is specified as a four part number. The parts are lt Major. Minor. lt Build. lt Revision. The assembly version is specified using an assembly attribute. Common practice is to update the major and minor version numbers for changes that break backwards compatibility. If you dont want to specify a build and revision number you can use a wild card and the compiler will automatically generate one for you. Examplesassembly Assembly. Version 1. 3. 3. Assembly. Version 1. Assembly Public Key Token. The assembly public key token is a short representation of the public key compiled in the assembly. The token value is the first 8 bytes of the SHA 1 hash of public key. Having a public key inside the assembly allows, once the assembly is signed, to verify its integrity. It also ensures that there will be no naming conflicts with shared assembly names. To generate a key pair we use the sn. Mono Strong. Name 0. Copyright 2. 00. 2, 2. Motus Technologies. Copyright 2. 00. 4 Novell. BSD licensed. A new strong name key pair has been generated in my. Once the key pair is generated we must then reference that key from inside of our assembly using an assembly attribute assembly Assembly. Key. File my. key. Installing Assemblies to The GACOnce you have given an assembly a proper shared name with a version and public key it can be installed into the GAC. Not all assemblies should be installed to the GAC. See the what should be installed to the GAC section to help you decide whether your assembly should be installed into the GAC. To install an assembly to the GAC we use the gacutil tool. Gacutil can be used to install assemblies, uninstall assemblies, and list the assemblies in the GAC. Here is a sample installation gacutil i gaclib. The i directive tells gacutil to install the assembly. If we want to see what assemblies we have installed in our GAC we can use the l directive gacutil l. The following assemblies are installed into the GAC. Accessibility, Version1. Cultureneutral. Public. Key. Tokenb. 03f. Accessibility, Version2. Cultureneutral. Public. Key. Tokenb. 03f.
