c# - WCF: The specified registry key does not exist in base.Channel call - Stack Overflow

Seems people have faced similar issues after installing a security patch for the .NET Framework: MS12-074: Vulnerabilities in .NET Framework could allow remote code execution: November 13, 2012

You can ask microsoft to fix it here

Workaround - Add the following registry key:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework]
"LegacyWPADSupport"=dword:00000000

For 64 bit machines

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework]
"LegacyWPADSupport"=dword:00000000
