I am planning to migrate a project from asp.NET 1.1 to 3.5.

Which one would be the best approach?

I create new project and migrate project to new project or direct open in .net 2008?

I have 6 class library and one main project have 900 asp pages.

Open the Project in VS2008. It will take care fo the rest. I had taken the same approach for 1.1 to 2.0(VS 2005) and then 2.0 to 3.5 migration(VS 2008).

 I convert to 2005 . but I have some error.

Hello,

You can directly open the solution in VS 2008. It will ask you to select the framework and you can change the framweork to what ever you want (Say 3.5).

It will have some errors related to deprecated methods. Please manually fix these. Also do a google search on issues related to migration.

Hello,

I Convert my project to .net 3.5  Successfully. and execute without problem.

But I can't  debug. i make new breackpoint and compile , but have problem

 "no symboles loaded to current document "

thanks

 Hello,

I think the problem is you are not attaching the debugger properly or with build.

Have U tried building the solution couple times?I have not worked on 2008 so not able to guess the problem.
