Question

I’m going to maintain an existing .NET 1.1 app for my client. VS.NET 2008 seems not to be able to build .NET 1.1 projects out-of-the-box but I don’t want to install VS.NET 2003 just for this particular project. Is it possible to use VS.NET 2008 for .NET 1.1 development? How?

Answer 1

According to Luke H’s blog, no:

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.
