.Net CF Versions?

[CWKJ]

I have some questions on .Net CF.

Currently my O2 XDA Flame is having v1.0.

Many Apps using v2.0 and even v3.5 Beta cannot be used.

I have download them both v2.0 & v3.5 Beta, but not sure which to use,

1. Can I jump from v1.0 to v3.5 Beta and v2.0 Apps will still work with v3.5 Beta?

2. Each version normally comes with PPC & WM Version, which should I use?

3. For O2 XDA Flame, should I use the ARM version or which version?

4. I cannot find the cab of v1.0, I am looking for it in case I want to downgrade. I only found the Sevice Pack 3 for developer version. I know I can also do a uninstall or a hard reset or do a restore from backup to get back v1.0.

You can have multiple versions of the .NET CF installed if you want. When a program runs, it will attempt to load the version it was compiled against. If that version is not available, it will attempt to load the highest version that is available, and hopefully it will be compatible with the app.

For example, if you run an app that was designed for framework version 1.1, and you have 2.0 and 3.5 installed, 3.5 will get loaded.

As for locating and installing the different frameworks, I can't be much help, except to suggest that, if an app you have didn't install the version it wants, you might be able to download the correct version by looking at the microsoft mobile website.

I thought there was only ONE COMPACT NET Framework and thats 2.0 SP1.

Do you have an answer for Q2 & Q3?

Took the courage to install NetCfV3.5Beta WM Version and manage to get downloaded Apps (SimpleOS) to work.

Without installing NetCfV2, direct from Flame's NetCfV1 to NetCfV3.5Beta, download Apps (TouchFlo3D, needed at least NetCfV2) works with NetCfV3.5Beta.

but with beta's it's not always the case
.net2 had issues with some .net1.1 stuff
