Hosting App-Domain from Visual Studio - VS is Unloading silently

[debnarayan]

Hi, I am trying to create a Visual Studio 2005 Add in, that should call an Winform application to gather some info from user. I have hosted the Form code in a new AppDomain and have obtained the required fields back via AppDomain.SetData and GetData methods. Problem is, VS is unloading silently, even if the WinForm did not throw any exception. Here is the code for the Exec method:

public void Exec(string commandName, vsCommandExecOption executeOption, ref object varIn, ref object varOut, ref bool handled)
{
handled = false;
if(executeOption == vsCommandExecOption.vsCommandExecOptionDoDefault)
{
if(commandName == "TestVSAddIn.Connect.TestVSAddIn")
{

                AppDomain wizardDomain = null;
                try
                {
                    if (String.IsNullOrEmpty(this.applicationWizardAssemblyName) || !File.Exists(this.applicationWizardAssemblyName))
                        throw new InvalidOperationException("Installation error.");

                    if (wizardDomain == null)
                    {
                        AppDomainSetup wizardDomainSetup = new AppDomainSetup();
                        wizardDomainSetup.ApplicationBase = applicationWizardAssemblyPath;
                        wizardDomainSetup.PrivateBinPath = applicationWizardAssemblyPath;
                        wizardDomain = AppDomain.CreateDomain("WizardDomain", null, wizardDomainSetup);

                        wizardDomain.SetData("RunningFromVS", true);
                    }

                    wizardDomain.ExecuteAssembly(applicationWizardAssemblyName);

                    if (wizardDomain.GetData("OpenInVS") != null && wizardDomain.GetData("SolutionPath") != null)
                    {
                        bool openInVS = Convert.ToBoolean(wizardDomain.GetData("OpenInVS"));
                        string solutionPath = Convert.ToString(wizardDomain.GetData("SolutionPath"));

                        if (\_applicationObject.Solution.IsOpen)
                        {
                            \_applicationObject.Solution.Close(true);
                        }

                        \_applicationObject.Solution.Open(solutionPath);
                    }
                }
                catch (Exception ex)
                {
                    try
                    {
                        Logger.LogThis("Error
