Using ASP.NET 1.1 on a machine with 2.0 installed

[Jon Skeet [C# MVP]]

I've recently run into an issue with a webapp running under ASP.NET
2.0. It runs fine under ASP.NET 1.1, and everything still works with
both versions installed so long as I manually select ASP.NET version
1.1 in the MMC. However, I'd rather do it in a configuration file or
something similar - is there any way of programmatically selecting
ASP.NET 1.1 rather than 2.0? Obviously in the future I'd like to make
the webapp work with 2.0, but fixing the working state in the first
place is more urgent.

I've looked for answers in various places, but they only seem to
mention the MMC. Is the version property available from scripting,
perhaps, if web.config doesn't help? (I can't find anything in
web.config which looks appropriate.)

Note that I don't want to configure the whole web site to run ASP.NET
1.1, just the single webapp.

Thanks,
Jon Skeet

Isn't it always the way? A colleague found this while I was posting the
question:

Basically, it looks like you can run the appropriate aspnet_regiis -sn
<path> to specify that that version of ASP.NET should be used for that
webapp.

Is that the best way of doing it?

Jon,

I believe you have discovered the two more straightforward ways to configure
a web application for a particular version of .NET. To be honest, while I'm
not that much of a GUI guy, I like the configuration tab in IIS. (The
jury's still out on the web.config configuration button however.)
