c# - The name "XYZ" does not exist in the namespace "clr-namespace:ABC" -

-

i working on creating markup extensions , started weird vs behaviours. have extracted , pinpointed issue in separate solution. problem vs can't create clr object in xaml.

here is:

view:

<window x:class="wpfapplication4.mainwindow"         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"         xmlns:wpfapplication4="clr-namespace:wpfapplication4">     <window.resources>         <wpfapplication4:dog x:key="doggy" />     </window.resources>     <grid /> </window>

code behind:

using system.windows;  namespace wpfapplication4 {     public partial class mainwindow : window     {         public mainwindow()         {             initializecomponent();         }     } }

dog class:

namespace wpfapplication4 {     public class dog     {      } }

app.xaml (no code in app.xaml.cs):

<application x:class="wpfapplication4.app"              xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"              xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"              startupuri="mainwindow.xaml">     <application.resources>      </application.resources> </application>

project settings

exception getting:

error   1   name "dog" not exist in namespace "clr-namespace:wpfapplication4". \\hopr1\folders$\vxk\documents\visual studio 2012\projects\wpfapplication4\mainwindow.xaml  6   9   wpfapplication4

i able run solution, designer fails "invalid markup" error ideas?

edit

i running vs 2012 update 2 same solution work in vs 2012 update 1

your solution running on network share. .net (and visual studio) applications can run permission / access issues when running on network share.

copy solution local drive (with full trust) , should fine.

it possible network drive working full trust - can find answers on stackoverflow , other places - in experience keep running obstacles when this, try avoid unless it's absolutely critical problem @ hand.

e.g. question gives instructions how this:

give fulltrust unc share visual studio 2012 , .net 4.0

i've ever tried vs2010 (as indicated in link) might have better joy 2012.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
