CreateExecution method not found #29

I have a problem with running basic HelloWorld example:

var q = new Query { Formula = "let hw = \"Hello World\" in hw" };
var pq = new PowerQueryCommand();
var result = pq.Execute(q);

Exception message from result gives me following info:

Method not found: 'System.Threading.Tasks.Task`1<Microsoft.Mashup.Tools.QueryExecutionResults> Microsoft.Mashup.Tools.QueryExecutor.CreateExecution(Microsoft.Data.Mashup.MashupConnectionStringBuilder, Microsoft.Mashup.Tools.CredentialStore, Boolean)'.

I suspect that this is related due to PowerQuerySdk.vsix 1.0.0.16 dependency.

I cannot find v1.0.016 anymore to test against this version, so i'm using current version 1.0.0.25

Is this known error?
