Spotfire Developer | All versions |
There are instances when we may have multiple custom extensions which reference Third Party dll ( e.g. Newtonsoft.Json). So if the version of these 3rd party dlls is different in different extensions, we may come across assembly conflict specific issues.
This could be a common issue when developing Spotfire extensions
Example error details:
"Could not load file or assembly 'Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)".
If an extension requires a certain version of a dll, or uses a dll not "always" available on the machine running the extension, then the dll should be included in the spk.
The included dlls need to have a Strong Name otherwise the system will not regard them as different versions.
So if everything is configured correctly it should work.
If a dll does not have a Strong Name then you must ensure there is only one of that dll and that anything compiled towards that dll can reach that dll.
