![]() ![]() NET Assembly Manifest. It is helpful to load an assembly using IL DASM and examine the manifest to see whether there is a strong name key available. NET binaries to peruse the contents, perhaps for viewing the method signatures or viewing the. ![]() Visual Studio ships with a handy utility – the Microsoft Intermediate Language Disassembler ( ILDASM.EXE ( tutorial)) – which can be used for disassembling. Approach #2: Viewing Strong Name Details with IL DASM If you need finer-grain control and wish to write low-level code to ascertain the strong-naming status of an assembly, you can do that too. (See note below – “Strong Names not for Security”.) So this technique is not appropriate for all uses, but might help in, say, an automated script that checks your about-to-be-released assemblies to make sure you remembered to add the strong names to them. Note that this will tell you whether it has SOME strong name, but does not tell you which one. Since the return value from sn.exe is 0 (zero) when the strong name is in place, and 1 (one) if not correctly strong named, you can test for this in a script by examining ERRORLEVEL, as in the following (put it into a text file called “sn-test.bat” for example and run as “sn-test foo.dll”): echo off if "%1"="" goto END NET Framework Strong Name Utility Version 8.1Ĭ:\WINDOWS\ismif32.dll does not represent a strongly named assembly ![]() All rights reserved.Īssembly 'C:\.\' is valid C:\> sn -v C:\WINDOWS\ismif32.dll Microsoft (R).

Here are the results when running against a strongly named assembly, then one that is not strongly named. You tell whether an Assembly/DLL has been successfully strong-named using the Strong Name Tool ( sn.exe) (which can be found somewhere like here: C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\sn.exe) by running the following at the command line: sn -vf NET Assembly is Strongly Named.Īpproach #1: Testing for Strong Name on Command Line or in a Script Then in the final section of this post the often confusing – though very important – differences between Strongly Named assemblies and Digitally Signed assemblies are clarified.īut first, here are three approaches for telling whether a. Towards the end, this post discusses use of Strong Names with Silverlight. (English language note: I assume the form “strongly named” is preferred over “strong named” since that’s the form used in the output of the sn.exe tool shown immediately below.) Here are several convenient ways to tell whether a. NET Assembly is Strongly Named (or has Strong Name) ![]()
