MissingMemberException

[triton]

Hi
I'm using "http://www.devart.com/dotconnect/sqlite ... _linq.html" to start linqConnect but my code return "MissingMemberException" with this message:

Method not found: 'Boolean Devart.Data.Linq.Engine.TypeHelpers.IsEnum(System.Type)'.



I'm using "LinqConnect 4.2 Express" .

Please help me.

I experience the same issue (using linqconnect 4.2.257 and sqlite)
Sample code:
MainDataContext context = new MainDataContext();
var query = from it in context.Companies
orderby it.CompanyID
select it;

foreach (Company comp in query)
Console.WriteLine("{0} | {1} | {2}", comp.CompanyID, comp.CompanyName, comp.Country);
Console.ReadLine();

Hi I have the same issue with the professional linq version since upgrading to the latest version 4.2.257.0. Previous version was not displaying this error.

The bug related to the MissingMethodException error is fixed.

It can be downloaded from http://www.devart.com/linqconnect/download.html (trial version) or from Registered Users' Area (for users with active subscription only).
