Telerik.OpenAccess.Query<T>

[Laurent Fabre]

Hi,

Since I switched to Visual 2010 I see an error upon namespace declaration :

"Using the generic type 'Telerik.OpenAccess.Query<T>' requires 1 type arguments"

Of course if I delete the declaration I cannot use the .Extent<T>() method anymore......

If add a reference to all the required Assemblies including Telerik.OpenAccess.40.Extensions but nothing seems to operate.

I'm pretty sure it happened when I switcher to framework 4.0 target platform.

Any hint would be greatly appreciated.

Ok I solved it by adding also the 3.5 extensions (which is a bit counter-intuitive...). Sometimes I seed a VistaDB 4.0 not found error and I don't use VistaDB to the best of my knowledge. Is this related to OpenAccess ?

Hi Laurent,

yes, adding the new Telerik.OpenAccess.35 assembly (containing the code that was formerly located in the Telerik.OpenAccess.Query assembly) is the right step.

Wrt. VistaDB: This database has been added in the latest release. How are you seeing such not found errors, when do they occur? 

All the best,

Ok :)

They occur systematically upon the first reload of the website wether it's dev or production, as soon as I hit reload a second time it disappear and never appear again (hopefully). My dev is a IIS 7.5 running Windows 7 x64 and my prod is an IIS 7 running Windows 2008 SP2. Both use ASP.NET MVC 2 and Framework 4.0. Looks like a race condition of some kind.

I already upgraded this morning and yes I had this issue priori the upgrade but I just looked at the properties of the OpenAccess.dll and it says 2010.1.312.2. Maybe that's a new build with the same version ?
