Microsoft.Win32.OpenFileDialog dosn't show while debugging?

Question

I'm building a application on Visual Studio 2015 in C#. I'm using Microsoft.Win32.OpenFileDialog to get a file from machine, but while debugging the code stands still at "dlg.showDialog();" and the dialog box dosn't shown up.

public static void OpenDialog()
        {
            Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();
            dlg.Title = "ABC";
            dlg.ShowDialog();
        }

Please suggest if there is any other way?

I have tested your code in my side and I did not face the error as you described and I can open the dialog successfully. So please try these suggestions:

1) make sure that your project is a desktop project rather than a console project.

2) reference PresentationFramework.dll under Add Reference-->Reference-->Assemblies-->select PresentationFramework .

3) disable any third party extensions under Tools --> Extensions and Updates to check whether an extension caused this behavior.

4) then close VS Instance, delete .vs hidden folder under solution folder, bin , obj folder, then restart your project and then test again.

Then you can set breakpoint to test whether it runs successfully.

5) try to create a new project to test these code and if it still does not work, please repair your VS(run the vs2015 installer program and click Repair ).
