Well, actually, if you compile with NET_2_0 defined for use with .Net 2.0, it uses System.Net.Mail.
However, the ASPNetTraceAppender does reference the System.Web namespace for access to the HttpContext class. In both versions 2.0 and 4.0 of the framework, this class is in System.Web.dll so there should be no difference from current development. ---------------------------------------------------------------------- Roy Chastain -----Original Message----- From: Ron Grabowski [mailto:rongrabow...@yahoo.com] Sent: Tuesday, December 01, 2009 21:26 To: Log4NET User Subject: Re: .NET 4.0 and Log4Net Well, its a known issue in the sense that its had that dependency for 8+ years: System.Web.Mail ________________________________ From: Tiernan OToole <lsmart...@gmail.com> To: log4net-user@logging.apache.org Sent: Tue, December 1, 2009 9:12:55 AM Subject: .NET 4.0 and Log4Net Good morning all. when trying to use Log4Net (1.2.10) with .NET 4.0, i am getting an error about Log4Net needing System.Web... is this a known issue? -- Tiernan O'Toole blog.lotas-smartman.net www.tiernanotoolephotography.com www.the-hairy-one.com
