How to distinguish if message is from ReSharper or Visual Studio - visual-studio

The text is in Italian, but the literal translation would be: the member wasn't fount in the data context ClustersManagementTabDesignViewModel.
<UserControl x:Class="ClustersManagementTabAdapterView"
xmlns:clusters="clr-namespace:Clusters"
d:DataContext="{d:DesignInstance Type=clusters:ClustersManagementTabDesignViewModel}"
mc:Ignorable="d" Background="White">
<telerik:RadGridView SelectedItem="{Binding SelectedItem, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
ItemsSource="{Binding ItemsCollection, Mode=OneWay}">
<telerik:RadGridView.Columns>
<telerik:GridViewDataColumn Header="Nome Cluster" DataMemberBinding="{Binding ClusterName}" Width="auto"/>
</telerik:RadGridView.Columns>
</telerik:RadGridView>
</UserControl>

This is not from ReSharper - it does not support any other languages except English. Easy way to check if an inspection is from ReSharper is to press "Ctrl-Alt-Shift-8" to disable all ReSharper's analysis in the opened file. Don't forget to press the combination again to enable the analysis.

Xamarin Forms XAML Image control has quit working

I have a working app that displays images. I started a new app and copied the code but this new app does not display images. Puzzled, I have tried many, many things to debug it. I eventually made a plain vanilla new project with only an Image control. As usual, I added the picture to the project using Add Existing Item. I confirmed that the image is there. It does not display the image. I noticed something different in Solution Explorer. Under the Solution, the first project has Dependencies listed under it. This is new. My previous apps have never had that. Now every new project I create has it. I also noticed that the Properties of the image was Build Action of None. I tried changing it to Content but that did not help. At this point, I am baffled and stuck. Did something change in Visual Studio? Here is the image test XAML.
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:local="clr-namespace:ImageTest"
x:Class="ImageTest.MainPage">

<!-- Place new controls here -->
<Image Source="gr8oz.png" />
<Label Text="Welcome to Xamarin.Forms!"
HorizontalOptions="Center"
VerticalOptions="CenterAndExpand" />
</StackLayout>
</ContentPage>
As I said, I have a working app that has been released. I copied this code into a new app and it does not work. In my investigation, I have found that the Image control does not work for me anymore.

I have searched and read everything that I can find (and yes, I have read the Microsoft doc about the Image class).
I am also curious why Dependencies suddenly appeared in the Shared Project folder. This is new too. How do I resolve them? See screenshot.
Dependencies under OFamV2.
I uninstalled Visual Studio, deleted the folder, reinstalled Visual Studio Community 2017 Version 15.8.8 and the problem is still there, even with a new project.
For Options, I select Cross Platform/ Mobile App/ Platform: Android and UWP/Code Sharing: .Net Standard.
Set image show you can see here , i think you have used that.
So reload your project,and rebuild it,you can try this.
More info:
Here is a similar disscussion about image show.
Suggest that better not copy code from other project about view,they may result some problems where you do not know.

How to (or why can't I) add a plain .xaml file to my Visual Studio solution and edit it within?

Status
I have the following (Visual Studio 2017) solution configuration:
created a new solution with one .csproject for post-build commands
added several other .csprojects to the solution via add existing project
now I want to add a plain .xaml file, which works via add an existing item to the solution, but throws the error:
Object reference not set to an instance of an object.
Problem
The item still appears, but a double-click to open it throws the same error and does not let me edit it.
Unwanted fixes
I can prevent this error by two ways (which I do not want):
rename the .xaml files to e.g. a .xaml.txt file ending (and name them back within the post-solution-build commands)
put the .xaml files into an own .csproj folder with a .cs file only defining the empty namespace ThisIsMyGraphicsElement { } and a Properties\AssemblyInfo.cs file
So my question is
How can I add and edit a plain .xaml file to my Visual Studio solution?
Edit
Here is an example code:
```
<UserControl
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

mc:Ignorable="d"
d:DesignHeight="410" d:DesignWidth="800">

</Grid.RowDefinitions>
<StackPanel HorizontalAlignment="Left" Height="200" VerticalAlignment="Top" Width="500" Margin="150,140,0,0" Grid.RowSpan="2">
<TextBox x:Name="textBox1" HorizontalAlignment="Center" Height="100" TextWrapping="Wrap" VerticalAlignment="Top" Width="366.865" Margin="0" Background="{x:Null}" FontSize="24" Text="Live happily ever after...
" BorderBrush="{x:Null}"/>
</StackPanel>
</Grid>
</UserControl>
```
As mentioned in comments/answers, adding a new (empty) .xaml file and pasting the code did not work as well.
Not sure what is happening here. You could try to create a new XAML within your project and then paste the XAML from the file you want to include. That's what I would try.
Edit: Not being able to comment.... I'm not the first to suggest this.

Windows phone ads not working

I am trying to integrate ads into a already successful deployed app. However no matter what I do, I cannot seem to get the ads working. I have tried using both the code version and the drag n' drop gui version. Neither of which I can get to work.
This is what I see: When it starts up it may flash for a split second white, where the ad is supposed to be, but none the less, no adds. It recognizes that it is where I place it, when I place it over a button, the button becomes unclickable. All being said, no default "microsoft advertising" image pops up. I have installed the ad SDK and have successfully been able to make the ads display in other project with ease.
What gives? This is very simple page and I cannot figure out what is wrong. It also seems that I cannot place an ad on any of the other pages either... I do have the Microsoft.Advertising.Mobile and Microsoft.Advertising. Mobile.UI included in the project and my internet is working (I have an project open at the same time with ads and it works)

I had the same issue and wrote a blog post about it. Here's the important stuff:
The symptoms of a problem with the SDK's AdControl seem to be pretty consistent: The page loads, the control flickers briefly, showing the hint of a 1 pixel frame, and then, poof. It collapses into nothingness, leaving only a black hole of dispair.
In theory, setting up the AdControl is simple. The documentation from Microsoft outlines the basics:
Download and install the Microsoft Advertising SDK.
Add a reference to Microsoft.Advertising.Mobile.UI.
Drag the control onto the page in the Visual Studio designer.
Set the AdUnitId and ApplicationId properties to either test values or actual live values, which you can obtain from Microsoft pubCenter.
But it couldn't be that easy. I followed the documentation carefully, but nothing was working. I couldn't even get test ads to show up, which seemed really weird. I even reverted to an older version of my app (yay source control!) and dropped in the new .dll. Failure.
Finally, I found a clue in an obscure forum post.
The Microsoft documentation neglects to mention several important details. You need to pay particular attention to the following if you're upgrading an existing project to the Mango ad SDK, as I was:
You must specify a height and width for the AdControl. Failing to specify the Height and Width attributes, or setting them to auto, will cause tears of frustration. I'd recommend 80 pixels high and 480 pixels wide, as that's the native size of the ads that Microsoft serves up.
It seems that you can't have two AdControls on the same page, or at least not in the same parent element. The second one will collapse. There might be a way around this, but I discovered it while building my demo app and didn't care to pursue a solution.
You must must must specify certain capabilities in your WMAppManifest.xml file. Since I was upgrading my app, I didn't have some of the newer capabilities declared. The one that was causing all the trouble was ID_CAP_IDENTITY_USER. The following capabilities are all required for the control to function correctly:
<Capabilities>
<Capability Name="ID_CAP_IDENTITY_USER"/>
<Capability Name="ID_CAP_MEDIALIB"/>
<Capability Name="ID_CAP_NETWORKING"/>
<Capability Name="ID_CAP_PHONEDIALER"/>
<Capability Name="ID_CAP_WEBBROWSERCOMPONENT"/>
</Capabilities>
Hope that helps!
I think your problem could come from (if you didn't remove it for posting it here):
<my:AdControl AdUnitId="Image480_80" ApplicationId="test_client" Height="80" HorizontalAlignment="Left" Margin="-12,458,0,0" Name="adControl1" VerticalAlignment="Top" Width="480" />
</Grid>
You have to use AdUnitId and ApplicationId which you get from pubCenter.
One more think to note for those still struggling
xmlns:ads="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI"
<ads:AdControl Height="80"
Width="480"
AdUnitId="Image480_80"
ApplicationId="test_client" />
As in example. Declaring ads and the namespace is super important.
In my project i just inserted the adcontrol part alt + enter for resharper to do the rest of the work which he didnt. He replaces ads with UI and there was no error compilation still the ads wouldn't show. When i declared ads myself and changed the adcontrol namespace. Everything worked fine.

WPF control frozen in Visual Studio 2010

I did a custom button control in WPF and I am trying to implement it in WinForms (c#). Now, the control is working and it compiles well, but I can't seem to access the elementhost - the control was not shown in the toolbox, and afterwards I saw it's frozen, i.e. I can't add it to the form. Since the project build process went without errors or warnings, I don't know what is causing the problem. Any help would be appreciated, thanks.
EDIT: Here's the code of the xaml file:
<Button x:Class="proba4.UserControl1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
d:DesignHeight="120" d:DesignWidth="300" IsEnabled="True">
<Button.Template>
<ControlTemplate TargetType="{x:Type Button}">
<Grid>
<Image Name="Normal" Source="C:\stuff\off_button.gif"/>
<Image Name="Pressed" Source="C:\stuff\on_button.gif" Visibility="Hidden"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsPressed" Value="True">
<Setter TargetName="Normal" Property="Visibility" Value="Hidden"/>
<Setter TargetName="Pressed" Property="Visibility" Value="Visible"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Button.Template>
</Button>
May be it is because you inherit your control from non-usercontrol class? In WPF the first rule is avoiding control inheritance. Try to use composition

How to get intellisense when doing XAML data bindings?

It would be nice if in XAML when I define ItemsControl/ItemsSource="{Binding AvailableContracts}" that Visual Studio would be smart enough to go find the property AvailableContracts on the ModelView which the DataContext is bound to, reflect it, and then when I type:
<TextBlock Text="{Binding Path=
it would pop up intellisense of the bindable properties that are available to me in my ContractModelView since AvailableContracts is a List collection.
I don't see why Visual Studio can't go follow this logical path and give me the needed intellisense. Can anyone explain what the disconnect here is? Or surely there is some way to "give it some help" so that it could provide intellisense. Any third-party tools to do this? Perhaps in VS2010? I hear MEF is going to make intellisense much better in VS2010, hope so.
This lack of databinding intellisense when writing my XAML views just feels like notepad. :-(
