相关疑难解决方法(0)

我在ClickOnce部署的应用程序中依赖于.NET 2.0 SP2(该ApplicationDeployment.CurrentDeployment.CheckForDetailedUpdate(false)方法仅适用于SP2).

    /// <summary>
    /// The SP2 bootstrapper does not allow HomeSite installation

    /// </summary>
    private void CheckDotNet2SP()
    {
        WaitHandle wh = new AutoResetEvent(true);
        try
        {
            wh.WaitOne(1); //this method is .NET 2.0 SP2 only
        }
        //NOTE: this catch does not catch the MissingMethodException
        catch (Exception) //change to catch(MissingMethodException) does not help
        {
            //report that .NET 2.0 SP2 is missing
        }
        finally …
