I. Visual Studio Code Name “Orcas” Known Issues

1. Visual Studio Tools for Office features require Microsoft Office 12

To use the Office projects in this CTP release of Visual Studio, you will need to install the Office Beta 2 Technical Refresh.

To resolve this issue

You can find the Office 12 Beta 2 Technical Refresh for download at: http://www.microsoft.com/office/preview/default.mspx or as a shortcut on the VPC desktop.

2. Samples on the usage of the ADO.NET stack

To resolve this issue

ADO.NET Samples can be downloaded online. The samples provide simple examples of programming console, web and win forms applications against tables in the Northwind Database in both VB and C#. If the link does not work, copy and paste http://www.microsoft.com/downloads/details.aspx?FamilyId=C14C451D-7043-44F0-87D7-845F1C238D64&displaylang=en into the browser.

3. ADO.NET Entities in this current drop do not support LINQ

To resolve this issue

The private CTP of ADO.NET (ADO.NET August CTP) does offer a preview of LINQ integration but that functionality does not work with the Orcas October CTP

4. No ADO.NET tools support for the Orcas October 2006 CTP

To resolve this issue

There is no tools support included in the Orcas October 2006 CTP . There is a publicly available ADO.NET Tools CTP . Please note these tools are for the ADO.NET August CTP.

5. LINQ (Language Integrated Query) in Orcas October 2006 CTP

Although parts of the LINQ feature set are available as part of Orcas in the October CTP, the full set of LINQ features is still in development. If you want to try out LINQ, we recommend you continue to use the May LINQ CTP which installs on top of Visual Studio 2005, and which includes more fully featured prototype versions of the C# and VB compilers, as well as the LINQ APIs.

To resolve this issue

If you would like to try out LINQ in the Orcas October 2006 CTP, here are some tips:

1)Manually add a reference in your project to System.Core.dll which can be found in \Windows\Microsoft.NET\Framework\v3.5.XXXXX\.

2)Use the static methods on System.Query.Sequence to access the LINQ to Objects functionality

6. Project Designer Missing Option Infer

Users can now control whether or not a variable’s type is inferred by typing “Option Infer [On | Off]” at the top of any code window. Just like the other options (Explicit, Strict etc…), Option Infer can be set at the project level and also the file level. For this CTP, the UI support for setting this at the project level is not in place.

To resolve this issue

By default, Option Infer is turned on at the project level for all non-upgraded projects. Although you can’t set it through the UI, you can still type “Option Infer On” or “Option Infer Off” at the individual file level.
