• When are response headers created in ASP.NET web forms?

  - by Jones

  I read somewhere the you can't remove response headers once they've been added. Given that, I'm wondering where in a standard ASP.NET web forms application do response headers get added initially. For example, these: Date Fri, 23 Apr 2010 16:25:56 GMT Server Microsoft-IIS/6.0 X-Powered-By ASP.NET Cache-Control private And can I stop it from happening? Do subsequent headers override old headers? Does my question even make sense? Thanks.

• Flex and .NET - What's a good way to get data into Flex, WebORB? Web Services?

  - by JC Grubbs

  Ok, I asked a question earlier about Flex and ADO.NET Data Services but didn't get much response so I thought I'd rephrase. Does anyone have any experience building Adobe Flex applications with a .NET back-end? If so, what architecture did you use and what third-party tools if any did you employ. I've read a little about doing Flex remoting with WebORB but it seems more complicated than it should be, are web services an adequate alternative?

• Can Visual Studio 2010 Test .net 3.5 SP1 Projects?

  - by Michael Stum

  I have some projects in a solution that are running on .net 3.5 SP1 (and can never ever be updated to 4.0 as they are SharePoint projects). When I try to create a new Visual C# Test Project in VS2010 Premium, I have to choose .net 4.0 which is apparently intended. Now I don't care about what my Unit Test project is (don't have to care about VS2008 users), but I do care if I can safely test 3.5 Projects in it due to the different CLRs and slight C# language differences?

• Git/SVN for asp.net development instead of VSS?

  At work, we are using ASP.net 2.0 and VSS. VSS is a beast, we are continually having issues with people checking out files and there is no branching - makes it crazy. I know SVN/GIT is mainly used by open source developers, are there any downsides to ASP.NET developers using it? I have been pushing for SVN internally, but am thinking GIT might also be a great option. Our team is spread across 3 continents.
