Hi,
when i load my addin i get this error : Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.
The problem started after I have installed the service pack 2.0 of SolidWorks 2013.
Attached "SLDWORKS.exe.config" that i have placed in my SolidWorks installation folder.
Best regards.
