WPF密码箱-调试时出现内部错误？

Question

UPDATE:

Due to the help from Devid Farinelli I was able to sort it out myself. This link helps to point out the issue but the described Workaround doesn't fit to Visual Studio 2015. If you're having the problem there, refer to this link. In my specific case it was a line where I called a control property without invoking the thread before. Not a big thing but with the error it was. Hope this helps some others maybe.

Thanks and greetings

I'm using a PasswordBox in a UserControl. To detect the user has entered both his username and a password, I'm disabling the Login button as long as one of both is empty. So far, so good, all is working as expected, the button gets enabled if both are containing something.

The thing is: I wanted to debug the method in behind code where I'm changing the button state but I'm getting an "internal error" message like:

Event-ID=0x20c. Exception code=0xc0000005, Eip=0x7226b264.

That's not the usual exception message window.

My method code on this is just

        private void txtCheckLoginEnable(object sender, EventArgs e)
    {
        if (tbPassword.SecurePassword.Length > 0 && tbUser.Text != "")
            cmdLogin.SetValue(Button.IsEnabledProperty, true);
        else
            cmdLogin.SetValue(Button.IsEnabledProperty, false);
    }

The event gets called from one of both TextBoxes. And as said, if not placing a stop point inside the method, nothing pops up.

Someone an idea on this? I'm not sure if it's an issue functionwise but as said, I'm not getting other bugs from it.
