Assembly Cache Viewer (sfushion.dll)
*) see ".NET Architecture", Appendix A: important directories Windows Explorer Add-In that visualizes the Global Assembly Cache (GAC) like an ordinary directory
actual paths: e.g.
assembly mscorlib: GAC* \NativeImages1_v1.0.3705\mscorlib\ 1.0.3300.0__b77a5c561934e089_be4960bd\mscorlib.dll
assembly System: GAC* \GAC\System\1.0.3300.0__b77a5c561934e089\System.dll
Native Image Generator (ngen.exe)
generates a native image (= a tranlation to machine code) of an assembly
thus the assembly is compiled only once on the target computer at install time (= install-time compilation); no need for new compilations on every program run (= just-in-time (JIT) compilation)
core assemblies of the .NET Framework are installed as native images per default: mscorlib, System, System.Drawing, System.Windows.Forms, ...
file size comparison: PE file native image: e.g. System.dll 1.216.512 Bytes as IL assembly 1.929.216 Bytes as native image
Global Assembly Cache Utility (gacutil.exe)
Command line tool for
installing assemblies in the GAC > gacutil -i GlobalLib.dll
removing assemblies from the GAC > gacutil -u GlobalLib
displaying the contents of the GAC > gacutil -l
supports counting the references to global assemblies > gacutil -ir GlobalLib.dll FILEPATH c:\Apps\MyApp.exe > gacutil -ur GlobalLib FILEPATH c:\Apps\MyApp.exe > gacutil -lr
the assembly cannot be removed from the GAC, while at least one reference to it still exists
Strong Name Tool (sn.exe)
Command line tool for
generating pairs of private & public keys > sn -k mykeys.snk
extracting the public key from a key pair > sn -p mykeys.snk mypubkey.snk
delayed signing of assemblies > sn -R MyLib.dll mykeys.snk
Strong Name for Assemblies
"strong" assembly name consists of:
name
version number (major.minor.build.revision)
culture attribute (usually neutral)
hash value of the public key
z.B. MyLib, Version=1.2.745.18000, Culture=en-US, PublicKeyToken=13a3f300fff94cef
Why sign an assembly?
only names of signed assembly are considered "strong"
only signed assemblies can be installed into the GAC
Delay-Signing
sn -k mykeys.snk [assembly: AssemblyKeyFile("mykeys.snk")] MyLib.cs csc /t:library MyLib.cs sn -p mykeys.snk mypubkeys.snk csc /t:library MyLib.cs sn -R MyLib.dll mykeys.snk [assembly: AssemblyKeyFile("mypubkeys.snk")]
[assembly: AssemblyDelaySign(true)] MyLib.cs MyLib.dll (signed) sign directly Delay-Signing
Code Access Security Policy Tool (caspol.exe)
Command line tool for
turning security checks on and off > caspol -security ( on | off )
adding/removing/changing/listing code groups > caspol -addgroup > caspol -remgroup > caspol -chggroup > caspol -listgroups
adding/removing/changing/listing permission sets > caspol -addpset > caspol -rempset > caspol -chgpset > caspol -listpset
...
commands target enterprise/machine/user security policy level > caspol -enterprise / -machine / -user / -all . . .
