XAML Parse Exception - xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

I was working on a WPF project on my PC last night, using VS 2010 Ultimate.

I have just opened it up on my Netbook with VS C# 2010 Express.

When I try to run it, it I am thrown an XAML Parse Exception which tells me that the line:

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Is the problem. I can't see a problem with it, I have never changed it and it looks like it is what it should be.

The Error:

'The invocation of the constructor on type 'WpfApplication1.MainWindow' that matches the specified binding constraints threw an exception.' Line number '3' and line position '9'.

Full XAML:

<Window x:Class="WpfApplication1.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

I had this error and changing exception reporting did not seem to help

I noticed that I was trying to call: 

var processClass = new ManagementClass(@"\server.domain1.co.uk\root\cimv2:Win32_Process");

Where \server should be \\server

Changing this fixed the issue but it is pretty annoying having an error message that doesn't tell you anything about your error.

I have actually noticed this error in a few places when a string has not been properly formed in wpf, so that could be a good place to start.

Try this one from reference

"Ur needed dll"->properties->copy to local->true (change it from false)

save & clean solution & then rebuild it. I think it will work(worked for me).

that xaml looks ok. there shouldnt be any problem with that. i think you try to get some data. are you trying get some message with your application? if so the default message size is 65536 bytes. increase that number in your app.config. also open the output windows while running you program and check if there are binding errors.

XAMLParseException is a common exception thrown in WPF. Unfortunately it isn't very helpful.

To help find out what the real error is, you can turn on exception reporting much earlier in Visual Studio. Default key combination is Ctrl + Alt + E. From there, check all the boxes.

Now the exception that is thrown in your code will be highlighted in the debugger.
