CF version after CF 2.0 install

[Peter Hartlén]

Hi!

Using C# I use System.Environment.Version.ToString(); to find the version of
Cmompact Framework. It works fine with CF 1 but after installation of CF 2 I
still get 1.0.4292.0.

I am also using WM2003 and VS 2003.

Should I use the technique described here instead:

You need to use VS2005 to use CF2.0.

I know I need VS2005 to develop applications that use CF2.0 specific
resources, I actually have VS2005 but have to wait for some device
manufacturer specific SDKs before I can start using it. Right now my only
interest is to deploy Compact Framework, I asked about this in a previous
post "CF 2.0 etc.".

Am I wrong to say a VS2003 developed application could run on a device with
CF2.0 installed?

The more interesting question here would be if the VS2003 developed
application can benefit from an installation of CF2.0 (otherwise I could
wait with this as well until we migrate to VS2005).

1. CF 1.0 assemblies (which is what you're building in Studio 2003) cannot
use CF 2.0 assemblies.
2. If a device has both CF 1.0 and 2.0 installed, then your 1.0 assemblies
will run fine, but they will use the 1.0 runtimes by default.
3. If a device only has CF 2.0 on it, you can try a version coercion, which
should work. You might gain perf benefits by doing so, but you'll want to
re-test everything for stability:

Aha!

I've missed this totally, been bogged down in terrible Delphi code for quite
a while now...

Thanks for the information!

Does this mean there are two totally seperate file sets installed for the
two framework versions?

So if I have a WM2003 machine with pre-installed CF1.0, I will add an
additional amount of files and the space they require by installing CF2.0?
The cab file is ~5.4MB, but what is the actuall install size?

Thanks,

Peter

CF2.0 is will set you back about 6 Mb, and 1.0 is around half of that.

Is it possible to de-install a ROM-installed CF?

Preferrably de-install CF1 when installing CF2

No. Not if the files are part of the OS-image. The files are most likey
located in a read only area of the file system so is not possible to
reclaim or reuse the space anyway.

That's about 5 MB uncompressed (e.g. on WM 5.0) and about 2 mb compressed
(e.g. on WM 2003).

What was terrible there? The fact that it was Delphi (I hope it wasn't
or can't see why) or the way the code was written?

Hello,

can VS2005 write CF 1.0 apps?
Otherwise if you don't needed some CF 2.0 specific features you would
require (at least on WM 2003 devices) to waste valuable memory with CF
2.0 runtimes you don't need.

Yes, Markus, VS2005 supports the creation of CF 1.0 apps on WM5.0 and
WM2003 platforms.
