I am seeing alot of errors where variables are not defined in the VB version of csla.net 3.5 build. In the C# version the same variables are being defined as var, which doesn't mean anything. How can this be fixed?

In C# var is used for an anonymous type...which definately has meaning and is on purpose.

Make sure you are trying to build with VS2008 and don't change the targeted framework from .Net 3.5 to anything else.

Yes, CSLA .NET 3.5 requires .NET 3.5.

If you are using .NET 2.0 or 3.0 then you should be using CSLA .NET 3.0.x.

I am using .net 3.5

The feature is called type inference. In C# it is like

var x = 10;

and in VB it is like

Dim x = 10

In both cases 'x' ends up being of type int/Integer.

In VB you can turn this feature on/off using an Option statement at the top of each file, or at the project level. The Csla project should have inference turned on - but perhaps somehow it is not turned on for you?

thanks rockford. i know this was a simple thing to explain, but it was something i needed to understand, and it wasn't being done in the previous versions of csla

my Option statements are turned on at the project level. I'm not sure which Option you are referring to, but Option Explicit = On, Option Strict = On, Option Compare = binary

In VS 2008 check

Tools

Options

Projects And Solutions

VB Defaults

Option Infer - set it to On.

I'm not working with VS2008. I have VS2005 which does not have Option Infer.

Well Csla 3.5 requires Vs2008 / .Net 3.5... so you should look at 3.0.3.

RockfordLhotka replied on Wednesday, March 26, 2008

To reiterate:

CSLA .NET 3.5 requires Microsoft .NET 3.5 and Visual Studio 2008.
