Framework 2.0 and 1.1

Framework 2.0 and 1.1

• VBScriptor

  We are having similar issue. We have an application developed in framework 1.1. Now in the field, one of our customers installed framework 2.0 runtime. After its installation, our application has stopped working. As I understand, we can have different versions of .NET runtime on the same computer. In this situation how can we explicitly tell the application to use framework 1.1 only Is there any thing that we configure in the computer I see this also as on-going potential problem, if the customer installs another application that requires framework 2.0.
  
  In this particular case, the application was installed on Windows 2003 server which has .NET 1.1 as a default component. We uninstalled 2.0, but it does not allows us to re-install 1.1. Any suggestion as to how to repair/re-insall the 1.1 again
  
  Will appriciate any help. Thank you very much

  Can you point me to a FAQ or more information on running 1.1 and 2.0 in parallel. Also, this thread should probably be pinned or something. I know a lot of developers - who aren't necessarily dummies, they are just too busy working - who believe that only one or the other of the frameworks can be installed at a given time. This will be a huge issue for you guys (MS) as most of us are putting off the move until dictated to do so by clients -- who themselves do not have the knowledge and are scared to pay for all the work to migrate everything at once -- a bit like Y2K.
  
  I myself want to move to ASP.NET 2.0 for example, but I am worried that I cannot imstall the 2.0 framework without ruining my 1.1 framework and hence my applications... I think that this is the same worry that Emu, and millions of others worldwide are having.
  
  Can I install Visual Studio 2005 and develop ASP.Net 2.0 applications and still have my Visual Studio 2003 on the same machine running against the 1.1 framework. Can you please point us to information about doing this, if possible. Thank you very much.

  Hi,
  
  1.It won't crash your system even if you have more than one .Net framework 
    installed. It will do side by side execution.
  
  2.Sometimes it needs to have both version to support the old applications b'coz
    some of the APIs are deprecated and obsoleted from .Net2.0
  
  thanks,
  Kedar

  Hey Emu -- I am not sure excatly what you are getting at about the support of 1.1, but we to plan to support 1.1 for several more years.   We have also worked to make sure that 2.0 is as compatable as possible with 1.1 such that you can move applications to take advantage of 2.0 features.

  Brad - great news that you plan to support 1.1 for several more years.  Does this mean that the 1.1 redist will remain on Windows Update alongside 2.0 (and later) for a number of years

  Thank you Kedar,
  the dependency is a very bad thing,
  i would like to hear reply from MS about 1.1 future , in win2003 its by default , and there no merging 1.1->2.0 .

  I haven't seen an FAQ specific to 2.0 come out online just yet (a lot of the docs are still getting published) but I haven't heard of any reason or changes that would prevent side by side execution from working the same way as is supported for 1.1 and 1.0.  VS 2003 and VS 2005 both will continue to function as normal if installed on the same machine.
