Can .net 2.0 app access/load .net 4.0 assemblies/dll's. Hi Eric, What a coincident just came online to update.
Eric thanks a lot for timely advice. I had decided on two options 1. run .net 2.0 project under .net 4.0 CLR 2 . I almost lost hope on the first option and end up doing the 2nd one, luckly the second option worked for me but still neede official document/links on WSE 2.0 support on .net 4.0. looking at eric's reply i started working on 1st option from scratch and guess what? Here are the details For .net 2.0 exe projects (windows/GUI & windows services) simply create/update "app.exe.config" file with note: after we add from VS studio config file we need to manually edit to append ".exe" to the file, by default vs creates "app.config" which does not work not sure why????
For more details check this link IIS7.0 for IIS 6.0 Setting Application Mappings in IIS 6.0 (IIS 6.0). all above changes where done manually but i need to figure out doing them programmatically i am hoping this is quite possible.

Practical ASP.NET Moving the Web.Config to Production in ASP.NET 4.0 Microsoft has another solution for managing your Web.config file as you move your site to production.
And, no matter what the name of this feature suggests, you don't have to learn XSLT to use it. The Web.config provides a central point of control for those few, but critical, items that change between the development/test environment and the production environment. Of course, it also means that if you deploy your Web.config file incorrectly, your production system ends up updating your development database and running in debug mode.
In many ways, the best solution to managing the Web.config file is the simplest: set up your Web.config on your production server and never change it again. With ASP.NET 4.0, Microsoft has another solution: Web.config transformation. There is really only two pieces of bad news here. Which config file's changes are applied is driven by the current setting in Build | Configuration. Extending Client-Side Programming in ASP.NET 4. Practical ASP.NET Extending Client-Side Programming in ASP.NET 4 ASP.NET 4 adds a wealth of features for client-side developers, including new ways of instantiating controls, a new infrastructure for managing libraries and some minor but much-needed tweaks.
Code-First Development with Entity Framework 4. .NET 4 ships with a much improved version of Entity Framework (EF) – a data access library that lives in the System.Data.Entity namespace.
When Entity Framework was first introduced with .NET 3.5 SP1, developers provided a lot of feedback on things they thought were incomplete with that first release. The SQL team did a good job of listening to this feedback, and really focused the EF that ships with .NET 4 on addressing it. Some of the big improvements in EF4 include: POCO Support: You can now define entities without requiring base classes or data persistence attributes. Lazy Loading Support: You can now load sub-objects of a model on demand instead of loading them up front. Visual Studio 2010 also includes much richer EF designer and tooling support. Code-First Development with EF In addition to supporting a designer-based development workflow, EF4 also enables a more code-centric option which we call “code first development”.
