I'm attempting to use the MediaUriElement in the custom (WPFMediaKit).

I've added it into the namespace like so;

xmlns:controls="clr-namespace:WPFMediaKit.DirectShow.Controls;assembly=WPFMediaKit"

and then I have tried to access it;

<Grid>
    <controls:MediaUriElement x:Name="mediaUriElement" />
</Grid>

however I just get an error: The name MediaUriElement does not exist in this namespace. VS does give me a suggestion to use it when I am typing though;

enter image description here

How can I correctly add this into my project?

  • @un-lucky unfortunately none of the answers seem to have fixed my issue – CBreeze Apr 11 '16 at 08:31
  • Is is because your project cannot compile or does it just bother you with the blue underline ? I have exact same scenario in some of my projects, but the project is compiling just fine, so I assumed that there was some bug in VS. – Nawed Nabi Zada Apr 11 '16 at 08:42
  • @NawedNabiZada It wouldn't bother me at all, however the project won't compile which is the issue here – CBreeze Apr 11 '16 at 08:50
  • Sometimes, if you have errors somewhere else in your code you will face same problem. Even if the problem isn't here, VS will indicate it as a problem here. Clean your solution, and rebuild it. Check the Error list, and fix all other errors, sometimes this kind of errors disappear when other errors are fixed. – Nawed Nabi Zada Apr 11 '16 at 08:55
  • Have you added `WPFMEdiaKit` dll to your project ? – StepUp Apr 11 '16 at 08:57
  • @StepUp I have added it as a reference yes – CBreeze Apr 11 '16 at 09:05
  • so, just do it as Nawed Nabi Zada said. Sometimes red rows happens, but it is not a reason to be scaried:). Just write your code without `IntelliSense`. – StepUp Apr 11 '16 at 09:08
  • @StepUp the program will not compile it isn't just a designer error – CBreeze Apr 11 '16 at 09:10

I've tried and it is worked. What I've done:

  1. Switched project from Framework 4.5 to Framework 4.0

  2. Added references such as DirectShowLib-2005.dll and WPFMediaKit.dll to the project

  3. Declared xaml namespace xmlns:controls="clr-namespace:WPFMediaKit.DirectShow.Controls;assembly=WPFMediaKit" like that:

    <Window x:Class="ExcelExportWpfApplication.MainWindow"
    ... The code omitted for the brevity...
    xmlns:controls="clr-namespace:WPFMediaKit.DirectShow.Controls;assembly=WPFMediaKit"
    xmlns:vm="clr-namespace:ExcelExportWpfApplication.ViewModel"        
    mc:Ignorable="d"
    Title="MainWindow" Height="550" Width="525" 
          WindowStartupLocation="CenterScreen">

  4. And just written in xaml:

    <controls:MediaUriElement Grid.Row="2"/>

  5. No errors
