[Mono-dev] 2.0 profile version of Mono tools ?

[Gert Driesen]

Hi,

Why is there no 2.0 profile version of all Mono tools (such as resgen, xsd,
...) ?

Right now, it's not possible to use any of these tools when you want to
build 2.0 applications.

If you have, for example, a resx file for which you need to reference a 2.0
assembly, then it's not possible to compile this resx file on Mono.

Any attempt to do this results in the following error:

** (resgen.exe:444): WARNING **: The class
System.Collections.Generic.IDictionary`2 could not be loaded, used in

This is because resgen is a 1.1 (1.0 profile) assembly (which loads some 1.1
system assemblies) and hence you end with a 1.0 runtime, which ofcourse
can't deal with 2.0 assemblies.

Why not just build all Mono tools in both 1.0 and 2.0 profile ? Even if the
source code is exactly the same, you still need these profile-specific
assemblies.

We would then have, for example, a resgen.exe in $prefix/lib/mono/1.0 and
$prefix/lib/mono/2.0. You can then even have a small wrapper script (named
resgen) that executes one of these assemblies based on some environment
variable (MONO_PROFILE) or something.

Isn't this better than having wsdl, wsdl2, wsdl3, ... ?

Any feedback is appreciated ...
