.NET Framework suddenly very slow! RRS feed

  • Question

  • Hello,

    since today all my .NET 3.5 Applications are starting up very slow, up to 15 seconds, and also my Visual Studio is getting slow or frozen while ending a debug session.
    Even if I start my project inside VS, is take many seconds to start, and after closing the application, it takes many seconds until I can edit my code. I tried to create a new WPF project in VS 2010 RC, and if I set .NET Framework to 4.0, all is fine, but downstepping to 3.5 the same problem. Does anyone has an idea what's the problem? I don't want to reinstall all on my computer...all applications works fine on other machines.

    I'm working on a Windows XP machine, both VS 2008 Prof. and VS 2010 RC installed

  • Does the same happen with a small HelloWorld-type app targetting 3.5?
    You can run it with xperf and see what is going on on your machine, or attach native debugger (e.g. windbg) and check out call stacks during the delay (make sure you are using MS symbol server), they could help you understand what is going on (for example if some part like .NET Framework or antivirus is waiting for network ...).

  • Some news! If I disconnect my network (no internet access), all is fine....really weird. Any suggestions?
