Bug in Visual Studio 2008 Add Service Reference for VB.NET

There appears to be a bug in how Visual Studio does "Add Service Reference" proxy generation for VB.NET projects.

I ran into this issue when trying to add a service reference to Bing Maps and I believe it is not limited to that. I think it stems from it misunderstanding that enum instance variables cannot be tested for equality using .Equals in VB... not sure why.

I think the solution is to simply replace the offending line:

If Me.enumfield.Equals(value) <> true Then

with

If Not Object.Equals(Me.enumfield ,Value) Then

BTW: DO NOT compare boolean results to True or False as they have done!

Use

If boolean_results Then

If Not boolean_results Then

[EDIT 2010-07-07]
Specifically, this block of code is wrong:

<System.Runtime.Serialization.DataMemberAttribute()>
_

Public Property CompareOperator() As SearchService.CompareOperator

Get


Return Me.CompareOperatorField

End Get


Set


If (Me.CompareOperatorField.Equals(value)
<> true) Then


Me.CompareOperatorField = value

Me.RaisePropertyChanged("CompareOperator")

End If


End Set


End Property

and should be replaced with this:

<System.Runtime.Serialization.DataMemberAttribute()>
_

Public Property CompareOperator() As SearchService.CompareOperator

Get


Return Me.CompareOperatorField

End Get


Set


If
Not Object.Equals(Me.CompareOperatorField,value) Then


Me.CompareOperatorField = value

Me.RaisePropertyChanged("CompareOperator")

End If


End Set


End Property

Made this edit so search engines would pick it up... so I can find my own fix next time I run into it. :) [/EDIT]
