Look like the below statement is expecting to convert the string into list/array of header but the string (content) is not in correct format.

VB

Dim varses = JsonConvert.DeserializeObject(Of Header())(content)

Try wrap the content string with []. see below for example.

VB

Dim content = "[{" _
    + """deviceEnrollmentTransactionID"" : ""5b1354db-60De-4a77-8bb2-cec0357c0cd0_1529483946450""," _
    + """completedOn"":""2018-06-20T0839:14Z""," _
    + """orders"":" _
    + "[{""orderNumber"":""SO_1234"", " _
    + """orderPostStatus"":""abc""," _
        + """orderPostStatusMessage"":""xxx.""" _
        + "}]," _
    + """statusCode"":""ERROR""" _
+ "}]"
        Dim varses = JsonConvert.DeserializeObject(Of Header())(content)

Convert a string with multiple header.

VB

Dim content = "[{" _
    + """deviceEnrollmentTransactionID"" : ""5b1354db-xxxx-4444-yyyy-cec0357c0cd0_1529483946450""," _
    + """completedOn"":""2018-07-20T0839:14Z""," _
    + """orders"":" _
    + "[{""orderNumber"":""SO_1234"", " _
    + """orderPostStatus"":""abc""," _
        + """orderPostStatusMessage"":""YYY.""" _
        + "}]," _
    + """statusCode"":""WHAT""" _
+ "},{" _
    + """deviceEnrollmentTransactionID"" : ""5b1354db-60De-4a77-8bb2-cec0357c0cd0_1529483946450""," _
    + """completedOn"":""2018-06-20T0839:14Z""," _
    + """orders"":" _
    + "[{""orderNumber"":""SO_1234"", " _
    + """orderPostStatus"":""abc""," _
        + """orderPostStatusMessage"":""xxx.""" _
        + "}]," _
    + """statusCode"":""ERROR""" _
+ "}]"
        Dim varses = JsonConvert.DeserializeObject(Of Header())(content)
