    Hi @VytautasSlivinskas-0957 ,

    Thank you for sharing detailed information with me.

    It seems that this issue is related to CLR, actually, Visual Studio 2010 is end of support and .NET Framework 3.5 is an old version of .NET Framework, so there are fewer related official documents which mentioned if VS 2010, .NET Framework 3.5, and VSTO project support SHA256.

    But, from the error message, I think .NET Framework 3.5 may not support SHA256, so I may suggest you update VS to a higher version, and use .NET Framework 4.0+(If possible).

    Best Regards,
