System.NotSupportedException

[Lars Adler]

Hi
i am recieving a System.NotSupportedException error when i try to execute the following code:

Dim scope As IObjectScope = ObjectScopeProvider1.GetNewObjectScope
Dim result = (From i In scope.Extent(Of Address)() Where i.Name1 <> String.Empty)

System.NotSupportedException:
Not implemented: Execution of 'Operators.CompareString' on the database server side currently not implemented..

what am i doing wrong ?

thanks in advance

Hi Lars Adler,

i can reproduce the issue which stems from the fact that VB/LINQ is translated differently to LINQ than C#.
We will provide a fix for this in the next version.

Hello Lars Adler,

there is a workaround available which can help you until this is fixed: you need to use the .net methods and avoid the vb syntax.

... Where Not i.Name.Equals(""))

Please note also, that System.Empty was also not recognized correctly.
We are working for a fix for both issues.

All the best,
