Wel, I am rebuilding the VC# 2002 project that I have deployment problems
with the 2003 version, hoping this solves the problems, but now I encounter
this wierd bug???

If I have the project, and do not compile with "Allow Unsafe Code
Blocks=false" set to true, then the project compiles and no problems.
BUT if I compile with "Allow Unsafe Code Blocks=true" then I het the error
below. With unsafe {} of unsave{} removed it dos not solve the problem.
Maybe this is also related to thge installation problem I had?????

(In VC# 2002 this compiled without problems. )

------ Build started: Project: CtRepair, Configuration: Debug .NET ------

Satellite assemblies could not be built because the main project output is
missing.

Well, when it shows that error, does it show which attribute it's
processing?

Does it happen if you just start a new effectively blank project and
turn unsafe code on?

No, only this line in the output: "error CS1577: Assembly generation
failed -- Unexpected exception processing
attribute -- System.ArgumentException: Invalid directory on URL"..

And this line as task: "Assembly generation failed -- Unexpected exception
processing attribute -- System.ArgumentException: Invalid directory on
URL.".

Yes,I just tested.

This is VC# 2003 standard.
But on this machine VC# standard and VC++ 2002 standard are also installed
so is VC 6 professional.
Also .NET 1.0, .NET 1.1 (all English version) and any critical update from
Windows...
(All official versions!)

Maybe this is related to the installation trouble I have. ???
 
Yes,I just tested.

That sounds like your installation of VC# is a bit broken.

It certainly works fine if I just turn unsafe code blocks on for a
random project in my VS.NET 2003 installation.

I just installed it today. But I am going to try the repair function, maybe
it solves the problem.
I did uninstall the VC# 2002 to be sure that I do not have conflict between
installations.

But thanks for the replies. :-)

I just reinstalled everyting (VC# 2003 standard), but the problem persits
I create a new project, compile=ok, then turn on to allow unsafe code and
the dreaded "error CS1577: Assembly generation failed -- Unexpected
exception processing....."

The 2003 did not have problems with this.
Any tips would be welcome. :-)

I repaired everything. The unsafe option still gives this dreaded error:

No, only this line in the output: "error CS1577: Assembly generation
failed -- Unexpected exception processing
attribute -- System.ArgumentException: Invalid directory on URL"..

And this line as task: "Assembly generation failed -- Unexpected exception
processing attribute -- System.ArgumentException: Invalid directory on
URL.".

It doens't matter if I create a completely new class project or empty form
project.

Then I uninstalled the VC# 2003 and VC# 2002 completely, rebooted and
reinstalled VC# 2003.
Guess what? This error is back once I try to compile allowing unsafe code.
:-(

And I must use unsafe code since I need pointer typecasting to read in our
file formats. .

VC# 2002 did compile without trouble!

Anybody out there that have any idea why this happens?
Or what it means?

I have no idea what directory or URL it is refering to...

I finally managed to discover that the error occurs in the CSharp csc.exe
compiler itself, and seems to be not part of my the program.
I took a supidly simple console program.

And I compile using the command line compiler like this:

***D:\Source\Scratch\Managed\Testing\ConsoleApplication1>csc.exe /out:clas
:exe /r:MSCorLib.dll class1.cs***

This is the result that I get, and the exe is there and works fine:

*** Microsoft (R) Visual C# .NET Compiler version 7.10.3052.4
***
***for Microsoft (R) .NET Framework version 1.1.4322
***
***Copyright (C) Microsoft Corporation 2001-2002. All rights reserved.
***

Now I add one simple additional command "/unsafe+"

***D:\Source\Scratch\Managed\Testing\ConsoleApplication1>csc.exe /out:clas
:exe /r:MSCorLib.dll /unsafe+ class1.cs***

And here is the result I get from the compiler

***Microsoft (R) Visual C# .NET Compiler version 7.10.3052.4
***
***for Microsoft (R) .NET Framework version 1.1.4322
***
***Copyright (C) Microsoft Corporation 2001-2002. All rights reserved.
***
***
***
***error CS1577: Assembly generation failed -- Unexpected exception
proces***
*** attribute -- System.ArgumentException: Invalid directory on URL
***

So it seems that this *System.ArgumentException* is an error from the
csc.exe compiler???

One odd thing is that when I use "/unsafe-" (minus) then it compiles
without problems.

This works fine using the VC# 2002!!!!! And it also works fine using VC#
2003 at a different computer installed from the same installation disk.

Mysteries, mysteries,....
Anyone idea's what else to check?

One final test I did was using the C# csc.exe from framework 1.0 and this
one DID compile with "/unsafe+" !!!!!
See below:
