3.     The J# 2.0 runtime upgrade will be made available through a release to web (RTW) and include support for 64-bit versions of the .NET Framework and additional bug fixes.

4.     Assemblies that are compiled with the J# 2.0 Upgrade will run on the .NET Framework 2.0, 3.0 and the future version of the .NET Framework to be released with Visual Studio “Orcas”

5.     Support for the J# 2.0 second edition redistributable will be 10 years (5 mainstream and 5 extended) from the time of its release. This will be the final release of the J# redistributable.

6.  Using Visual Studio Tools for Office with Microsoft Office

To take advantage of Visual Studio Tools for Office (VSTO) in this release, you need to install either Microsoft Office 2003 or the RTM version of  2007 Microsoft Office System.  This release does not work with pre-release versions of Office 2007.  It is also not recommended to install both Office 2003 and Office 2007 on the same development machine.

If you do not have 2007 Microsoft Office RTM, you can download the trial version at:  http://office.microsoft.com/en-us/help/HA101687261033.aspx.

When using Visual Studio 2007 with Visual Studio 2005 or Visual Studio Tools for Office 2005 SE installed on a single development machine, please consider the following issues:

·         Side-by-side scenarios are not fully implemented for Office projects in this release and it is recommended that you do not install this release of VS 2007 on a machine with VS 2005 if you plan to work with Office projects.

·         Use of Office 2003 is not supported when both VS 2005 and this release of VS 2007 are on the same machine. 

·         Upgrading existing VS 2005 Office projects does not work properly in this release.  It is recommended that you do not attempt to upgrade projects with this release.  

·         Uninstalling this release of VS 2007 from a machine that also contains VS 2005 will require VS 2005 to be repaired.  You can repair your VS 2005, VSTO 2005 SE and Office 2003 environment by doing the following:

·         Uninstall this release of Visual Studio 2007 completely.

·         Uninstall Visual Studio Tools for Office 2007 Runtime if still on the machine.

·         Repair VSTOR.exe  Note: a repair of VS 2005 or VSTO 2005 SE might be necessary for other Visual Studio 2005 features as well.

 

To resolve this issue

No workaround is available for this issue

 

II. Product Issues

1. 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.

2. Incorrect Documentation For Query Variables in LINQ

In the MSDN documentation for LINQ, under "Introduction to LINQ Queries" and elsewhere, it is stated that the query variable receives and stores the query results when the query is executed. This is incorrect and will be corrected in future versions of the documentation. In fact, the concrete sequences returned from a query invocation are accessed through the iteration variable in the foreach loop. The query variable itself does not store an actual sequence of values unless it is explicitly converted (cast) to a List<T> (List Of T in Visual Basic)  or Array  instance through a call to the ToList or ToArray extension method.  The separation of the query from the results is a fundamental principle of the LINQ design. Among other benefits it enables queries to be reused any number of times, and to be modified after they are initially created, either prior to or after execution.

To resolve this issue

The issue is with the documentation, not with the product bits and will be corrected in future releases of the documentation.

3. Visual Basic Upgrade Wizard causes Unexpected Exception 

Running the Visual Basic Upgrade Wizard by opening a Visual Basic 6.0 project from the File / Open menu causes the following exception to occur:

Unexpected exception occurred during upgrade engine operation: Retrieving the COM class factory for component with CLSID {EB29F2BC-A843-4C09-9355-03E58D51EC29} failed due to the following error: 80080005.

To resolve this issue

At this time there is no work around for this problem.

4. Publish Tab in the Properties Page does not work for Office projects.

On the Properties page, selecting the Publish tab will cause Visual Studio to fail.

To resolve this issue

Do not select the Publish tab from the Properties page. Instead, to publish a solution, right-click the project name in the Solution Explorer and select Publish.

5. 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 winforms 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=5C12FE07-E646-49C2-887F-8CC070B37247&displaylang=en into the browser.

6. 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 January 2007 CTP.

7. No ADO.NET tools support for the Orcas January 2007 CTP

To resolve this issue
