Strong name signature not valid

[SiberaIndustries]

Since I've ported a ClickOnce application from .NET Framework 4.6.1 to .NET Standard 2.0, the message "Strong assembly name signature not valid for Microsoft.SqlServer.Assessment.Types.dll" appears when trying to install or update the application. So the next step was to verify the assembly strong name by using the Strong Name Tool to make sure, that everything is fine, but:

> sn.exe -v Microsoft.SqlServer.Assessment.Types.dll

Microsoft (R) .NET Framework Strong Name Utility Version 4.0.30319.0
Copyright (c) Microsoft Corporation. All rights reserved.

Microsoft.SqlServer.Assessment.Types.dll is a delay-signed or test-signed assembly

Additional information:

• The assembly versions 161.46041.41 and 161.46367.54 ended up in the same result
• This issue looks very similar to this
• @markingmyname / @olprod: The root package, which is required for Server Management Objects (SMOs), is:
  • Microsoft.SqlServer.SqlManagementObjects
  • Microsoft.SqlServer.Assessment
    • Microsoft.SqlServer.Assessment.Authoring
    • Microsoft.SqlServer.Assessment.Types.dll
• This issue appears on windows server machines but the software runs on different machines and I would like to avoid temporary workarounds such as editing the registry and activate the strong name bypass feature because of the forced validation on windows server machines

Thank you for this feedback! Please, update Microsoft.SqlServer.Assessment.Authoring package reference in the application to the latest version. Did this work?

[SiberaIndustries]

Your solution works, thanks!

Will this issue be fixed in future versions of the Microsoft.SqlServer.SqlManagementObjects package or do I have to make sure that the correct version of Microsoft.SqlServer.Assessment.Authoring is used?

[aguzev]

Sure, since we know the cause, the fix can be applied to Microsoft.SqlSerever.SqlManagementObjects as well.

Fixed in v161.46437.65 of the Microsoft.SqlServer.SqlManagementObjects package.
