.NET 1.1 and .NET 2.0 compatibility question

[intrader]

Is it possible to run assemblies generated for .NET 1.1 under .NET 2.0?

I am not sure I am expressing the question properly. The situation is
that we have some developers using Visual Studio 2003 and others using
Visual Studio 2005. Both groups are generating Windows Forms and Web
Applications; the IIS for each group is configured appropriately with as
to the version of the framework. The clients are are also segregated as
to the version of the framework.

We would like to configure the clients and the servers with .net 2.0
framework. Will the clients and IIS run .NET 1.1 assemblies?

Thanks

First, you can specify the version of ASP.NET handler that IIS use
Second, you can specify the desired assembly version in your app config

As I understand your answers:
1. NET2.0 runs NET1.1 assemblies runwithout change except that the app
config must state whether assembly is 1.1 or 2.0. (by the way does this
affect the build?)
2. IIS must be configured for a virtual directory to use the appropriate
handler.

Is this correct? or am I still not understanding?

Thanks

Both version works fine side-by-side, in you 2.0 app u can just reference
to the desired 1.1 class library and to work without problems.
Redirect is required when u have the same library but build in different
versions

Yep, as I remember u need just specify the version of aspnet.dll for your
virtual folder
