| You may get this error when using [[library|WinSCP .NET assembly]] from restricted environments, such as [[library_ssis|SSIS]]. To use the assembly from SSIS, it needs to be [[library_install#gac|installed to GAC]]. Also make sure you have installed the same version that you reference in your SSIS package. Alternatively, you can [[library_ssis#subscribe|subscribe ''AppDomain.AssemblyResolve'' event]] to allow loading the assembly. | You may get this error when using [[library|WinSCP .NET assembly]] from restricted environments, such as [[library_ssis|SSIS]].

| Also make sure you use the same version (ideally the latest) of WinSCP both for obtaining the fingerprint in WinSCP GUI and using the fingerprint in WinSCP .NET assembly. Older versions do not support modern SHA-256 fingerprints. So the fingerprint formats may be incompatible (and less safe). | Also make sure you use the same version (ideally the latest) of WinSCP both for obtaining the fingerprint in WinSCP GUI and using the fingerprint in WinSCP .NET assembly.
