DLL compatibility - Sitefinity - Front- & Back-End Development

Hi everyone, I've been involved in some projects now, going thru sitefinity versions like
4.0, 4.1 SP1, 4.1 SP3,
and I have some widgets into dlls...
I've been compiling my dlls against the corresponding versions from the sitefinity project manager.
Some widgets I reuse on projects, but I have to recompile them against their respective version on the main site...
mainly against the proper Telerik.OpenAccess.dll, Telerik.Sitefinity.dll, Telerik.Sitefinity.Model.dll, Telerik.Web.Ui.dll

Is there a way I can avoid this ?
I want to put some widgets into the marketplace... how can I make them "multi-version" compatible ?

thanks in advance :)

Hi,

If you have simple widgets which do not use our assemblies you are free to distribute them with any version of Sitefinity. There is a bindingRedirect property which you can use to redirect to different versions of DLLs, but again you will need to recompile the custom widget.

However there is no applicable way ( for now ) to have custom controls/widget dlls to "skip" the build action if they reference to particular assembly of Sitefinity ( like those you describe ).

Hi,

I am facing similar issue for a custom widget.

I have made a custom widget i.e. dll using Telerik.OpenAccess.dll (Ver : 2016.1.224.1), Telerik.Sitefinity.dll (Ver : 9.0.6010.0), Telerik.Sitefinity.Model.dll (Ver : 9.0.6010.0), Telerik.Web.Ui.dll (Ver : 2016.1.225.40). Now this widget working fine where same version is available within "SitefinityWebApp".

But it is giving error if we add this widget to other "SitefinityWebApp" project where Telerik.Sitefinity.dll version : 9.0.5950.0, Telerik.OpenAccess.dll version : 2015.3.1221.1.

Anyone please help me how I will control/manage this issue ?

Thanks,

Tapas

Hello,

Please, check the following KB article:
http://www.sitefinity.com/developer-network/knowledge-base/details/could-not-load-file-or-assembly-error-when-upgrading-to-sitefinity

You should set it for the assemblies which version mismatches.
