Hi,
What is the benefit of using the Pure option over the Mixed one. Is there a
better performance?
We have a lot of stuff in c++ with mfc support en we want to use in our .net
apps. With mixed setting we can compile including the mfc part of our code.
We can get rid of the mfc code but it will cost us some effort so we can use
the pure setting in that case.
If there is not much benefit then we can leave it as it is (sparing us some
couple of days of work).
Thank you in advance.

with /pure option, you can't have unmanaged class or function.
You can't have native code but you have not to be conform CLS (you can
if you want of course).
With this mode, no MFC, no IJW ...
So, the code is faster (because no transition managed/unmanaged).
best regards,
Nico

Hi,

The primary benefit of using /clr:pure (or /clr:safe) is that you end up
with a verifiable assembly that can be deployed and executed in partial
trust scenarios.
You may (or may not) get some benefit by avoiding native/managed transitions
as well, but that's not really what /clr:pure is about.

Thanks Carl,
You mention the option safe but it looks like i can use some unmanaged code
which makes it not illegible for partial trusted scenario's or am i wrong?
Takes us much less effort to get to this stage of being instead of the pure
one.

If I understand correctly, /clr:safe makes the assembly verifiable, but it
will still require some elevated permissions to run. If you need to run in
the most restrictive environment, then /clr:pure is your answer.

/clr:safe is more restrictive than /clr:pure http://msdn2.microsoft.com/en-us/library/k8d11d4s.aspx

I get this error
error C3181: invalid operand for __typeof, expected a fully defined managed type

Is there any way so that I can perfom "Enum::GetName" on the Enum of unmanaged code?
Please suggest

The MSDN documentation says that the GetLastError function can give
undefined behavior when compiling with /clr:pure switch. Does this statement
apply to both C++ interop and P/Invoke? If yes, does it mean that we have to
use Marshal::GetLastWin32Error to check the last error code?

I have a small C++/CLI application which calls an unmanaged lib.
It seems like I can't use /clr:pure and link with the unmanaged lib (LNK1313
error).
The problem I have is that compiling with /clr adds a dependency on several
msvc*.dll:s which adds some unwanted complexity to the installation.
Is it possible to avoid the msvc*.dll dependency without explicit p/invoke?

hi all.
I was creating a program in c++ and have to use various libraries. the problem was that some libraries need the clr and one of them unfortunately need clr\pure.
I want to know if is possible to use the both (clr and pure) in the same program? if yes, how i do it?
i have to said that my level of programming is weak (basic).
