Rookie build and deployment a dynamic library question

I had a request to write a dll library using C#, it should be build under .NET 3.5.

I've build the library (it's a simple TCP client) using Visual Studio 2005 with .NET 2.0.50727.

I'm assuming that I can not deliver this library since it's built against wrong .net I have more .NET versions installed on my development machine but it looks like I can't switch the .net in properties like JDK versions in eclipse for a particular project.

Is the only proper way of doing this is installing Visual Studio 2008 Express with 3.5 .NET?

Or some C# sdk with a开发者_运维知识库ppropriate compiler (the thing is that I don't know the syntax for the c# compiler and NANT would be pain in the ass at this stage)?

As jgauffin already mentioned your .Net 2.0 assembly will work fine in .Net 3.5.

And switching to another .Net Framework is just downwards possible.

• So with VS2010 you can built against .Net 4, 3.5, 2.0 and 1.1
• With VS2008 you can built against .Net 3.5, 2.0 and 1.1
• With VS2005 you can built only against .Net 2.0
• With VS2003 you can built only against .Net 1.1

So if you really need it just go and download it from here.

3.5 is just 2.0 with additional libraries. Your DLL will work fine from a .Net 3.5 application.

I might be wrong, but I think that 3.5 was introduced with Visual Studio 2008 and cannot be built against with 2005. That's why you can't switch version.
