CLS Compliance

[Guest]

I have a number of classes, none of which use non CLS Compliant data types.
These classes are compiled into an assembly.
however when using this assembly a function (for example) that returns one
of these classes gives a compiler warning "Return type of MyFunction is not
CLS compliant"
this occurs with every class in the assembly.

why is this?

further to this, the project is VB2005, and has been upgraded from vb2003

got it!

its because the code is migrated vb2003!

if i create a new project and copy/paste the code in evertything is fine!

hi,
can someone explain why? Is it documented somewhere? because I plan on
migrating much much much code from VB2003 to VB2005 in a near future, so I
want to know if it's normal behavior or if there are precise cases where it
does that...

Thanks

Hi,
i cant explain it but...

Note The current Microsoft Visual Basic compiler intentionally does not
generate a CLS-compliance warning, however, a future release of the compiler
will issue that warning.

from:-
http://msdn.microsoft.com/library/d...rlrfsystemclscompliantattributeclasstopic.asp

wether this is significant i dont know.

basically what i did intitally was create a vb2005 project and add in a vb
2003 vb class file this project referenced some vb 2005 assemblies, all of
which then appeared as non cls compliant.

for the second attempt i created another vb2005 project, created an empty
class file and pasted in the code from the vb2003 class, then set up the
references and all was fine!

a colleague has experienced identical problems

it ***might*** be something to do with referncing the vb2005 assemblies, buy
i havent tried this.
looking at posts on the net this seems a common problem, but i havent seen
an explanation:-(

thanks a lot... it will probably save me some time to know at least one way
to solve the problem.
