  • Make IIS 7.5 application pools run as NETWORK SERVICE

    There is a break change in IIS 7.5 on Windows 7 and Windows Server 2008 R2. The default identity for running an application pool is "ApplicationPoolIdentity".  If you have a web application developed against application pools running with NETWORK SERVICE on IIS6/7, it might break after migrated to IIS 7.5 due to default application pool identity change.

  • Mixed mode assembly Error After Upgrading to DotNet 4.0

    After upgrading existing DotNet 2.0 or 3.5 application to DotNet 4.0, you might see following error message

    Mixed mode assembly is built against version ‘v2.0.50727’ of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

    To fix this issue, put a config file next to your exe called <exename>.exe.config with the following content:

    <configuration>
    <startup useLegacyV2RuntimeActivationPolicy=”true”>
    <supportedRuntime version=”v4.0″/>
    </startup>
    </configuration>

    Or if your exe already has config file, you can just append <startup> element section. To know more detail, check out Mark Miller’s post What is useLegacyV2RuntimeActivationPolicy for?

    Update – 2011/11/15.

    Just hit a similar issue today when I referrence SMO in a DotNet 4 Executable

    Microsoft.SqlServer.Management.Dac.DacException: Unable to install DacInstance. Please verify the components of the application. —> System.IO.FileLoadException: Mixed mode assembly is built against version ‘v2.0.50727’ of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

    The solution is same – in app.config file of the executable, add the following settings:

    <configuration>
    <startup useLegacyV2RuntimeActivationPolicy=”true”>
    <supportedRuntime version=”v4.0″/>
    </startup>
    </configuration>

  • Hyper-V VM Slow on Windows Server 2008 R2

    I recently upgraded my virtual machine hosting server from Window Server 2008 to Windows Server 2008 R2. There are some noticeable performance drop, especially on virtual machines that handles big log files, the automation script execution time can take 200% or more than it was in a VMHOST with Windows Server 2008.

    I have done some testing and the performance downgrade seem introduced by the new power management system in windows server 2008 R2. There are 3 build in power plan in Windows Server 2008 R2

    • Balanced (recommended)
    • High Performance
    • Power Saver

    The default power plan in Windows Server 2008 R2 is Balanced. After I change Power Plan to High Performance and the performance downgrade issue does no occur any more. My guess is when power plan is set to balance, applications might not full utilize all available hardware resources.

    You can also checkout this post for Set the power configuration to High Performance in scripts.
