'System.AccessViolationException' occured in Oracle.DataAccess.dll

869869Jun 19 2011 — edited Feb 12 2013

Hi everyone,

I've just moved my development environment to a new machine and oddly I cannot run my .NET 4 app in Visual Studio 2010 any more. Whenever I run the .NET 4 app - no matter if it's in debug mode or not - I get the error "A first chance exception of type 'System.AccessViolationException' occurred in Oracle.DataAccess.dll" and WebDev.WebServer40.exe crashes at the point where it tries to connect to Oracle. My environment is

WinXP, Oracle 11gR2 client, ODAC112021 (same ORA_HOME as full client), Visual Studio 2010 SP1, .NET 4

I've already googled for this problem but couldn't find anything helpful. Can anyone point me in the right direction?

thank you
Oliver
