VS 2008 Compiling to .NET 2.0 With Errors   

Hi there,

    I've discovered quite a disturbing attribute of VS 2008.  I *had* a 
perfectly working 2.0 application compiling under VS 2005, all worked 
excellently.

    I then upgraded to VS 2008, all went as well as you would expect, with 
the exception of C++ libraries that needed updating to be compliant with VS 
2008, but those parts are irrelevant at the moment as the code in issue is 
VB.NET.

    So anyway, I have the application working on 2 Vista machines, it works 
great.  During a test session I was notified by the tester that the 
application crashed on startup, and just wouldn't start, even after 
uninstalling / reinstalling, this was since compiling to 2008, but targeting 
.NET 2.0.  The error in the system event log merely gives one piece of 
useful information "System.MissingMethodException".

    http://msdn2.microsoft.com/en-us/library/zk1a255s(VS.80).aspx

    So after racking my brains for a while and going through several 
different attempts at debugging this issue I came to one possible solution. 
I will also point out that this error is *non* trappable, it just slips 
right under the net and crashes the application, so no debug information for 
me.  As for the possible solution?  .NET Framework 2.0 SP1, which I 
downloaded and attempted to install.

    Error!  You can't install that on Vista, you must install .NET Framework 
3.0 which has the service pack built into it.  Anyway, I opted for .NET 3.5 
instead, just incase, which took roughly an hour to install, much to my 
amazement.

    Anyway, it fixed the problem!

    So the bug, VS 2008 compiles to .NET Framework 2.0 Service Pack 1, yet 
lets you call a function which apparently doesn't event exist without the 
service pack.  What is this function?  I have no idea yet, as far as I know 
I'm not calling anything new, I've merely got the application compiling and 
deployed as normal but under VS 2008.

    Any input or ideas on this would be greatly appreciated.

    Oh the joy of joys! :)

Nick.

Re: VS 2008 Compiling to .NET 2.0 With Errors   

I found the cause of the problem

Visual Studio 2008 exposes the property "AutoUpgradeEnabled" for the common 
dialogs, this isn't availanle on .NET 2.0 pre SP1.

Basically, if you are using 2008 and compiling to .NET 2.0, *don't use this 
property*!!
