SDK - Custom Connector - .NET 3.5 vs .NET 4

[#1]

Dear all,

I want to built a custom connector for my QlikView deployment but I'm faced with a compatibility issue. I'm not a .NET programmer so I hope someone can point me in the right direction.

The Connector client lib from QlikView works only in .NET 4 applications. In my company we have a couple of webservices with client libs that work under .NET 3.5. Is there a way where I can combine both?

Thanks in advance

I'm not sure if this works for everyone but for me it did:
