In WPF .NET5 ClickOnce publish I have added an FileAssociation
i.e:
<FileAssociation Include=".text">
<Visible>false</Visible>
<Description>prosjekt text</Description>
<Progid>text</Progid>
<DefaultIcon>icon.ico</DefaultIcon>
</FileAssociation>
When clicking a file in FileExplorer my app launches fine.
Now I need the filepath for the file. Im not able to retrieve the file name in the application. Looking at threads on WPF, clickonce .net framework, they refer to doing this: AppDomain.CurrentDomain.SetupInformation.ActivationArguments.ActivationData[0]
But this is not available in .net5? Or maybe im missing a package?
Im not getting the file name via Environment.GetCommandLineArgs() or StartupEventArgs either.

I have a Silverlight app made in Visual Studio 2010 and I want to put it on a website but I don't have the slightest clue how.
I've looked at all the msdn documentation and they all mention a .xap file that is the file you use on the website but there is no .xap and I can't find out how to compile my code into a .xap file.
Also, when I run the App and look at the source in the browser, it has my code compiled into the .xap file, but there is no .xap file!
So my question is simply how do you go about getting a Silverlight app on a website because I've been trying for hours and I can't figure it out.
A sample html or aspx page is included when you create the solution. This is the page that the browser navigates to when you hit F5. You can take that page as a basic example of how to embed a Silverlight app in a page. You should find it in the project folder.
Silverlight projects are commonly built into a XAP file when you hit "Build" in VS. This file lives in the bin/Release or bin/Debug folder and basically contains your whole application.
Steps to create a silverlight application Hosted in a web site,
Select Silverlight Application Template while adding new project in VS2010
When you click Ok, ensure that Host the Silverlight application in a new web site is Checked.(It will create a new ASP.Net web application to host the Silverlight)
If you haven't checked the Host the Silverlight application in a new web site option, you can add a new ASP.Net Web application project and then go to its properties and select Silverlight Applications option in left pane. Then Click Add, select your Silverlight Application to be hosted and click ok. You are done now.
But If haven't selected the Silverlight Application Template, then you might have created a Silverlight Class Library. It wont generate any xap file. It just gives a dll. So you need to recreate a project as mentioned above.
I believe that in Silverlight whenever you create a project, right at the beginning, it will ask you if you want to create a web app automatically. If you chose yes, something like YOUR_PROJECT_NAME.web will be created, go into that folder, you will find a folder called ClientBin.
The .xap file will be inside that folder.
HTH
I'm new to WPF, and created a 1st simplistic WPF application that I want it to run in a webbrowser, IE or Fox.
1 - Within the Visual Studio project, I created a /Images folder with a few .jpg files
On the WPF xaml form I have 1 image and 1 button.
When application starts, the image displays /Images/img1.jpg
When User clicks the button the image must display /Images/img2.jpg
How can I force the VS publisher to include the Images folder? Apparently I can't see it in the ApplicationFiles ?
2 - Though I was able to program and run this small app on my local computer, I'm getting lost when it comes to deploying to my hosting ASP where I have a Windows hosting account that runs .NET 3.5!
From Microsoft WPF website they say I shall deploy 3 files:
"The Application Executable .exe
The Deployment Manifest .xbap
The application Manifest .manifest
The .xbap file contains the information that ClickOnce uses to deploy the application and has the .xbap extension."
But I can's see no .xbap files at all within the published stuff!!!
Any clue please?
To answer your first question:
The images will be embedded in the compiled application, so you will not see the images in the application files.
Note:
The build action of images added to your project is 'Resource' by default - leave this as is.
Do not use the resources tab in the Project properties window, just drop and drag the images into the Images folder in the solution explorer.
To help answer your second question:
Did you create the project as an WPF Browser Application?
In your .csproj file you should see the following:
<HostInBrowser>true</HostInBrowser>
<Install>False</Install>
<ApplicationExtension>.xbap</ApplicationExtension>
<TargetZone>Internet</TargetZone>
If not, just recreate the project as a WPF Browser Application and copy your files from the existing project to the new one.
I added a Silverlight application to my ASP.NET website. Visual Studio made a new silverlight project and added its xap to the ClientBin folder under the project of my website. So both the projects are under one solution.
My Silverlight app is supposed to read an xml file and I was unable to make it access the file from the client bin folder under the website project. Adding a reference to that project does not work since it says only references to other silverlight applications can be added. Right now its working when the file is under the silverlight project but not when it is under the website project.
how can I make it read the file from website project?
The project structure is
WEBSITE1 (solution)
-WEBSITE1 (project)
-ClientBin
-file0.xml
-silverlightchart.xap
-SilverlightChart
-file1.xml
I can access file1.xml using
XDocument document = XDocument.Load("file1.xml");
I want to access file0.xml but no path works for me, for e.g,
XDocument document = XDocument.Load("~/ClientBin/file0.xml");
and WEBSITE1 is the startup project
You should be able to read a file from the ClientBin folder simply enough without needing to do anything special. At a guess I would say the you have accidentally set the Silverlight application as the startup project. In this scenario you want the website to be the startup project then either have the Silverlight apps test page marked as the start page or to navigate to the silverlight page once the browser has started.
Edit
The problem you have is that the Load method is synchronous but Silverlight does not support synchronous access to web resources. Hence passing a Uri to the Load method will only work if the that Uri can be fulfilled by content in the Xap. Thats why an Xml file in the silverlight project works because it ends up in the Xap.
To fetch Xml from the site you need to do this:-
WebClient client = new WebClient();
client.DownloadStringCompleted += (s, args) =>
{
XDocument document = XDocument.Load(args.result);
SomeFunctionToContinueWithDocumentProcess(document);
}
client.DownloadStringAsync(new Uri("file0.xml", UriKind.Relative);
// code exits here but _document won't be loaded yet
I want to use localization feature for Validation messages, for eg-
[Required(ErrorMessageResourceName = "RequiredField", ErrorMessageResourceType = typeof( ))]
public string someText
{ get... set...}
I'm using MVVM pattern so this property is in my model(its a differnt project inside same solution of silverlight) and all my localization resources are in the App.current.Resources. How can I set the ErrorMessageResourceType to my App resources?
Please suggest.
Thanks in advance

Well apparently Localization of error messages isnt as straightforward. You are supposed to add a resource file to the MyApp.Web project, that is the asp.net site that hosts your silverlight app, then add that resource to the silverlight app, then you will be able todo the code you stated in your question after some tweaks, follow the instructions below
This section explores how error
messages can be localized by storing
them in resource files and sharing
them across tiers.
The example uses .NET RIA Services
walkthrough project as the base
project and builds on top of it.
Let's say we want to add a validation
error as a resource for LoginID field.
Create a new ‘Resources' folder in the HRApp.Web project
(server project)
Add a new resource file to this folder and name it
ValidationErrorResources.resx
Double click on the .RESX file to bring up resource designer
page
Add a new string resource with Name= LoginIDValidationError and
Value= "LoginID field is required"
Change the access modifier to ‘Public' by clicking on the ‘Access
Modifier' drop down UI and selecting
‘Public' and save the project. This
generates a ValidationErrorResources
class in the HRApp.Web.Resources
namespace.
Open ‘OrganizationService.metadata.cs' file
and add the following ‘Required' field
validation to LoginID member. Specify
the error message resource name and
resource type values by setting the
corresponding attribute members as
shown below.
[Required(ErrorMessageResourceName =
"LoginIDValidationError",
ErrorMessageResourceType =
typeof(ValidationErrorResources))]
public string LoginID;
Now we want to share this resource
file in the Silverlight project
(client project). To do this,
Create a folder Web\Resources in the HRApp project
(folder structure must match the
resource file namespace on the server
side)
Select Resources folder and bring up Add Existing file dialog,
browse to the server side resource
file folder location
Select ValidationErrorResources.resx and
ValidationErrorResources.designer.cs
files, and add them as link files to
the Silverlight project. Save the
project file
Open HRApp.csproj file in notepad , locate the section where
.designer.cs file is included and add
the highlighted 3 lines to this
section
<Compile
Include="..\HRApp.Web\Resources\ValidationErrorResources.Designer.cs">
<AutoGen>True</AutoGen>
<DesignTime>True</DesignTime>
<DependentUpon>ValidationErrorResources.resx</DependentUpon>
<Link>Web\Resources\ValidationErrorResources.Designer.cs</Link>
</Compile>
Save the project file and reload the project in Visual Studio
Build the solution and run
Now whenever the validation fails for
the LoginID field the error message
from the resource file is shown to the
user. The resource file can now be
customized to store locale specific
error messages.
This solution almost worked for me. I had to made some arrangements to work with a data model (edmx) located in one project, DataDomainService (Ria) in other and the Silverlight access layer in other project.
When i compile the HRApp equivalent in my situation, the metadata containing the validation info for some property is not generated. It says that the client has no access to the ValidationErrorResources type. But after following all the instructions mentioned above plus some others to get a correct resource namespace, the client CAN access ValidationErrorResources.
It works if i write it myself to the generated Silverlight class.
So seems like this kind of project separation is not quite supported by the class generator...
But thanks anyway, this post was quite helpful and maybe i'll make it all work in a couple of days.
:D
When I did this recently this thred helped alot: http://forums.asp.net/t/1433699.aspx
In particular "...the resource file must be converter to a class before being able to reference it in the typeof of the ErrorMessageResourceType in the data annotation..."
Also there are a few other useful hits from the main search engines: http://www.liquidjelly.co.uk/supersearch/?q=silverlight%20dataannotations%20localization&lang=en-GB
I'm working on a Silverlight project with the WCF RIA Services beta. I'm using the BlahDomainService.metadata.cs file to validate a field by adding validation attributes, e.g. [RegularExpression]. It was working so I'm trying to put the Error message in a resource file and now it isn't working. The RegEx validation isn't being run on the client, though it is being run on the server.
Any idea what might be causing this?
In the generated code file on the client, I see this error:
// Unable to generate the following attribute due to the following error(s):
//
// - The validation attribute 'System.ComponentModel.DataAnnotations.RegularExpressionAttribute' declared ErrorMessageResourceName='RegExError' which was not found on declared ErrorMessageResourceType 'Blah.Web.Resources.SharedResources'.
// [RegularExpressionAttribute("yawn", ErrorMessageResourceName = "RegExError", ErrorMessageResourceType = typeof(Blah.Web.Resources.SharedResources))]
How I got where I am
I created the SharedResources.resx (and Vs created SharedResources.Designer.cs) file in the .Web project in a folder called Resources. In the Silverlight project, I created a Web folder and in that a Resources folder. To this Resources folder, I did Add > Existing Item and then added the SharedResources.resx and .Designer.cs using the Add as Link option. The idea was that this would keep the namespaces the same for the two resources classes. I then edited the .csproj file to make the .Designer.cs file a dependency of the .resx file, using the Silverlight Business Application template as a reference.
I built the solution and tested it and the RegEx validation throws no error, which is bad. Then I found the message above. To verify that my linking was working, in Home.xaml.cs, I typed:
System.Diagnostics.Debug.WriteLine(Web.Resources.SharedResources.RegExError);
and saw the error in the Output window in VS. I also submitted the changes to the service and in the EntitiesInError, on the VaidationErrors, I can see the error message, so I know it's working server-side. It's just the client-side that isn't. Any idea why it's not working?
You also have add a resources (.resx) as a link in the client silverlight project for the web project.
See template Silverlight Bussiness Application in VS 2010. It has a very good sample.
Everything was okay except that I hadn't set the AccessModifier for the .resx to Public. Once I'd done that and Rebuilt All, it worked.
