Florian Hockmann commented on TINKERPOP-1880:
---------------------------------------------

I just tried to verify the signature with the {{[Strong 
Name-Tool|https://docs.microsoft.com/de-de/dotnet/framework/tools/sn-exe-strong-name-tool]}}
 and it indeed reports the signatures as invalid:
{code:java}
> .\sn.exe -v D:\Downloads\Gremlin.Net.dll

Microsoft (R) .NET Framework-Dienstprogramm für starke Namen, Version 
4.0.30319.0
Copyright (c) Microsoft Corporation. Alle Rechte vorbehalten.

Die Assembly konnte nicht überprüft werden -- Fehler bei der Überprüfung des 
starken Namens.{code}
The output is in German but the last line roughly translates to: _Could not 
verify the assembly – Error while verifying the strong name_.

However, the signature for Gremlin.Net 0.2.2 was valid which was the last 
package that I published from my own repository. So there must be a difference 
in our deployment processes here.

[~kstephan]: Did you enable strong name checking somehow in IIS or does it 
always enforce valid signatures when a signature is present? When you don't 
need the strong name, then you can use in the meantime version 3.3.0-rc1 or 
3.2.6-rc1 as they weren't strong name signed.

> Gremlin.NET Strong name signature could not be verified. (HRESULT: 0x80131045)
