Unable to compile code when using OrderClose class

Question

I\'m trying to build a plugin that does some operations on a salesorder. I also have to set a order as fulfilled. I found on the SDK documentation an extract that must be us

Answer 1

OrderClose is in the Assembly "Microsoft.Crm.Sdk.Proxy" (in Microsoft.Crm.Sdk.Proxy.dll)

Have you added Microsoft.Crm.Sdk.Proxy.dll as a reference? Not just

using Microsoft.Crm.Sdk.Messages;

but actually going over to the solution explorer pane and right clicking References > Add Reference and choosing Microsoft.Crm.Sdk.Proxy.dll.

Edit: Right clicking on something red-squigglied and picking "Resolve" won't work unless the correct assembly is referenced.
