Running 1.1 and 2.0 Side-By-Side

Is it possible to run a ASP.NET 1.1 site and a 2.0 side-by-side in the same web site or virtural directory? Since I'm not sure if the web.config can be shared so I don't know if this is possible. We need to do this to slowly migrate our site.

I had a similar problem. I have a web application (Framework 1.1) in production, and decided to develop the new tools for this web application using the new VS 2005 (framework 2.0). I had a few problems and solved them hosting the 1.1 webforms in different application pools than the 2.0 webform (also dlls, etc). This is on IIS 6.0 under Windows Server 2003
I posted it here:
If you have any doubt just ask me.

Same website: yes. Same application: no. Each application needs to have their own versions of ISAPIs registered, and much of ASP.NETs's integration in IIS is via ISAPI extensions. But, yes, they can run on same machine and/or site just fine.

Differences between .net 1, .net 1.1, .net 2.0 and .net 3.0 #2
Hi, This seems to be a common question, but i havent got an answer yet:(Can, any one please explain me the differences between these versions.If you keep your feet firmly on the ground, you'll have trouble putting on your pants! There are too many differences for one email - - from 1.0 to 1.1 (not a whole lot of real change, other than fixes, at least compared to 1.1 to 2.0) With 2.0, there were many new declarative controls, with many new ideas added in With 3.0, it's a superset of 2.0 - instead of replacing the installation completely, it just 'added on' new functionality - I would...

Running .net version 2.0 and 1.1 side by side
Hi there, I read a thread on this forum which suggested that it's possible to intall both versions 2.0 and 1.1 on the same server. Can someone please provide me more information on how this works. for example, how do you tell the application the use Version 1.1. instead of version 2? It seems to me that once you have version 2 installed it takes over version one and you can't go back but I'm sure I'm just inexperienced. One other thing, sometimes I need to compile C# classes to produce libraries (.dll). Right now in my command prompt I have access to the c# compiler for version 2. Surelly,...

From 2.1.2 to 3.1 or 2.1.2 to 3.0.13 to 3.1
I'm checking back in after being away for a couple of months and I missed the 3.1 release. I can't seem to find any info on what's new in 3.1 and also what the upgrade path should be. So, is the recommended path for upgrading from v 2.1.2 to go directly to 3.1 or do I need to go to 3.0.13 first? Are there any big issues in 3.1 that make it a "gotta have it" version?I did a couple of 2.1.2 to 3.0.12 upgrades but haven't upgraded to or tested 3.1 yet. I have one 2.1.2 site that is commercial and I need it to be down as little time as possible. It also has a lot of third party modules...

Running 1.X & 2.0 side by side guide
Hello, Does any one know of a good guide on how install and run .net 2.0 along side .net 1.X? (Windows Server 2000 / IIS) Thanks! Hi Scott, Here are a few quick notes below: 1) When you install ASP.NET 2.0 on an IIS6 server that has ASP.NET 1.1 already installed on it, all existing applications on the box will continue to run with ASP.NET v1.1. 2) The version of ASP.NET that a particular application uses is controlled by right-clicking on an vdir/application and pulling up its properties.  There is an "ASP.NET" tab in the properties dialog box that you can use t...
