Hello everyone,

I am running a VB.net console application in VS 2015 pointing to an SDE SQL Database in ArcSDE 10.4.

I am getting the following error message when creating queryFilter. and featurescount does not have any value. This code works fine in 10.2 and VS 2012 pointing to SDE 10.2 Oracle.

' Create the query filter.

Dim queryFilter As IQueryFilter

queryFilter = New QueryFilterClass()

' Select the fields to be returned

queryFilter.SubFields = "INCID"

queryFilter.WhereClause = "INCID = " & strContentID

queryFilter.WhereClause = "INCID = 10772"

Dim featuresCount As Integer = 0

featuresCount = pFeatureClass.FeatureCount(queryFilter)

' feature count = 0, not found, then create feature

' feature count > 1, check if the version matches

If featuresCount = 0 Then
