So the multi-targeting will not support the .NET 1.1 framework?

The company I work for has a lot of applications which are required to be built using the .NET 1.1 framework, but would like to consolidate our Visual Studio development tools.

No - Visual Studio 2008 will not support targeting .Net Framework 1.1. This is something we really wanted to be able to support - since we know there are a lot of .NET developers working on .NET 1.1 applications. However, it would have been significantly more difficult to go back and support .NET 1.1 which was a substantially different runtime.

Thus, to fit in this release, the decision ended up being either to not support multitargeting at all - or to support only targeting .NET2.0 and greater. Because we really wanted Visual Studio 2008 to be a great tool for at least both .NET 3.0 and .NET 3.5 - we decided to put in the most multitargeting support we could fit in this release.

Luke - Thanks for your response. Guess we'll have to wait for a hack like with VS2005 so we can integreate TFS 2008 with .NET 1.1!

System.Data replacement after install VS 2008

Greg — Sat, 22 Mar 2008 00:13:38 GMT

I've got some problems with VS 2008 Multitargeting feature. After install VS 2008, my .Net Framework 2 System.Data assembly was somehow replaced for a newer version. The assembly version is the same but the behavior. Since installation the enum System.Data.SqlDbType is the new one with DaTime2, DateTimeOffset, and so on (introduced in .NET Framework 3.5). May it be a bug?

re: .NET Framework Multitargeting in Visual Studio 2008 (aka Orcas)

LukeH — Sat, 22 Mar 2008 00:49:05 GMT

Greg -

It sounds like this is related to the "red bits" issue I mentioned near the end of the post. Installing the 3.5 framework also installs a service pack for the 2.0 framework, and this service pack does include a small number of new types/members. I believe the things you are seeing are in this category. Krzysztof has a blog post about some FxCop rules that can help ensure you are not accidentally using this new functionality - if you want to be sure your apps will continue to run on machines which don't have 2.0 SP1.

See http://blogs.msdn.com/kcwalina/archive/2007/10/02/Multi_2D00_TargetingAndFxCop.aspx.

About not targeting .NET 1.1....why couldn't you just supporting building to .NET 1.1 with no debug ability...I successfully got VS 2008 to compile in.NET 1.1 but I would like to find a way to add the .NET 1.1 framework tot he list and it could link to the custom MSBuild. Is that possible?

ADD SUPPORT FOR 1.1!!!

Grunion — Wed, 11 Jun 2008 18:15:13 GMT

.NET 1.1 needs to be supported as .NET Framework 1.1 is the only framework that majority of the existing computer today has by default. I understand you want people to use the newer better framework, but unless you make .net Framework 2.0+ a part of critical updates, Visual Studio 2008 will be *completely useless* to a huge percentage of developers.

re: .NET Framework Multitargeting in Visual Studio 2008 (aka Orcas)

Trevor Daniel — Sat, 09 Aug 2008 22:57:55 GMT

Yes, Please give support for 1.1!!

I back up the support of targeting v1.1 in VS2008, or otherwise we will need to install both VS2003 and 2008 to develop applications for different versions of .NET application.

"Websites are different in this regard - you cannot use the new language features in a web site targeting .NET 2.0 or .NET 3.0. This restriction is in place because Web Sites need to compile on the web server, and this requires that the new compilers be installed on the Web Server. Since these new compilers come as part of the .NET 3.5 framework, this framework is required on the web server to use new language features."

You should reword that section of your article because it's extremely confusing. You make it sound like the code won't compile if you use C# 3.5 syntax in a website. That is not true. You *can* use C# 3.5 syntax in website code and it *will* compile just fine in VS 2008 (I just verified this). It's just that when you deploy it to the server, you'll be in for a rude awakening if you don't have 3.5 framework installed on server.

I just returned to programming having never used any dot net platform. VB6 was the last one I used.

I have no problem with the languages, but the compatibility seems to be as big a mess as COM was.

I have downloaded dozens of code samples from MS site and elsewhere for (a) Outlook integration and (b) basic tapi programming.

Both areas I have done previously.

Not a single code sample will load and run in visual studio 2008.

They run through the conversion process and then 20 or thirty errors.

I fin things like the outlook object model doesn't support a particular object specified in the sample code etc. Although all the references are there, they are not recognised.

Am I missing some important piece of the jigsaw?

This all sounds nice and simple, but in practice:

1. Using VS 2008 Express Edition, the "new project" dialog does not give a choice regarding version.

2. If you open an empty C# project with 3.5 (the only option), without even typing a single line of code, then you change it to, say, 2.0, there are two errors - Could not resolve assumbly Sysmte.Xml.Linq and System.Data.DataSetExtensions.

Um. Great job?

So I'll pick around and try to find the old 2005 disks I had back in the day....

Hello. Thanks for the writeup.

Perhaps my current trouble is related...

VS2003/1.1 unable to reference a COM interface (DLL) built in VS2008/3.5. And interestingly the same work can be referenced by VB6 through the exported TLB file.

Is it possible to support multiple frameworks from a single assembly? How?

Thanks,

Adam
