Hi ,

From last two days i a facing one issue. I have windows 2003 64 bit server . I installed MOSS 2007. With the same I installed Vs 2008.

Now when I create a webservice application on VS 2008 and refer Sharepoint dll . It builds properly .

but as soon as i try to run it thorws an exception

Attempted to load a 64-bit assembly on a 32-bit platform. Use ReflectionOnlyLoad() instead if trying to load for reflection purposes

It seems your program is referencing a 64-bit only assembly. That should not be a problem on a 64-bit operating system, unless you haven't installed the 64-bit version of the .NET framework or you are forcing your app to run in 32-bit mode. I assume it is the latter.

Hi Hans,

I just installed the VS 2008 . I think VS alwyas run on 32 bit only. Do you want to say that VS should be of 64 bit .

can you please let me know how to debug the .net application using 64 bit assembly ?

when i open the task manager it shows me devenv32*, it means .net runs with 32 bit.

so how can I resolve the issue. I have IIS 6 . but i dont think i am using IIS as rt now Ijust want to run my applicaton from VS run

Yes, the IDE is only available as a 32-bit process. The debugger is however available in both flavors. Necessarily so, you couldn't debug a 64-bit process otherwise. You'll find it back in Taskmgr.exe as msvsmon.exe

HI Hans ,

Do you mean that I have to install the 64 bit debugger. If it is so, then can u please let me know is there any downloadable availabe on MS site or it by default comes with VS 2008.

I am still pulling my hairs. I am not able to get the things resolve and still searching for the perfect solution .

Please let me know is there is any setting I have to change to debug the 64 bit assembly in VS 2008.?

Thanks in advance

Anil

No, it is not a problem with your tools. Your 32-bit program is trying to load a 64-bit assembly, that's not possible. You'll have to find out which one. I suspect you'll find more help in a Sharepoint forum.

Hi Hans,

Thanks for the reply. Just i want to know can we develop an application which will use 64 bit assembly on VS 2008 and will be able to debug it.

It is a generic query not specific to Sharepoint. So if I want to create a application on VS 2008 (which is installed on win 2k3 64 bit) which refer a 64 bit assembly and I want to debug it. Is this possible ? If yes , what setup is required.

Thanks

Of course, it is a well supported scenario for both VS2005 and 2008. Nothing special is required.

We seem to be going around in circles. A 32-bit program cannot use 64-bit code. Without you telling us anything about the 32-bit program and why it isn't a 64-bit program or why it is trying to load a 64-bit assembly, we can't help you.

Hi I am new to 64 bit OS. Till now i Develop everything on 32 bit.
I had not made any program as 32 bit. I just open the VS2008 IDE and there I select new project as Web Service Application . In webservice application I refer SharePoint Dll.
