Re: [sqlite] ADO.NET Provider, targeting any cpu
Hi, It is working for a classic application. But for a website (or a web application), the directories x86 and x64 should be in the ~/Bin directory or in ~/ ? Thanks.

[sqlite] ADO.NET Provider, targeting any cpu
Hi, I don't know if question has already been asked, and i appologize if it is the case... For the SQLite ADO.NET provider, there are precompiled binaries for both x86 and x64. Is there a way to have an assembly targeting any cpu, that chooses by itself the right dll to use at runtime ? I did something like this some time ago : 2 classes, one for x86 dll, one for x64 dll, implementing same interface. And at runtime, a function to get the right native methods class, by trying to load one, and catch BadImageFormatException, trying next... Thanks.

The System.Data.SQLite managed-only assembly, when the native library pre-loading code is enabled (which it is by default starting with release 1.0.80.0), will now attempt to detect the processor architecture of the process it is being loaded into and then it will attempt to load the native interop library from an appropriately named subdirectory (e.g. x86, x64, etc). In order to take advantage of this feature, the System.Data.SQLite managed-only assembly should be deployed with the other managed binaries in your application and the native interop libraries should be deployed in platform-specific sub-directories underneath that directory, as follows: appDir\YourApp.exe appDir\System.Data.SQLite.dll (managed-only assembly) appDir\x86\SQLite.Interop.dll (x86 native-only interop library) appDir\x64\SQLite.Interop.dll (x64 native-only interop library) If this feature does not work properly in your environment, it can be disabled by setting the No_PreLoadSQLite environment variable prior to loading and/or using the System.Data.SQLite assembly. -- Joe Mistachkin ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
