I'm trying to use the DeploymentCatalog to load my service implementations by MEF. I have the implementation in a single xap. when I use the following code to download it , every thing is ok :
var catalog = new DeploymentCatalog("MyXap.xap");
catalog.DownloadAsync();
I put my xap on a remote server , say on http://ip:90/Myxap.xap, when I write the same code but with the uri , it throws a deployment exception:
var catalog = new DeploymentCatalog(new Uri("http://ip:90/MyXap.xap",UriKind.Absolute));catalog.DownloadAsync();
Any help .
Thanks in advance ...
If the XAP you are trying to download is hosted at a different domain (or different port, I think) than your Silverlight App is, you will need a cross domain policy file on the site that hosts your XAP to allow your Silverlight App to access it.
If that's not the problem, you'll need to provide more information. Edit your question to include the full text of the deployment exception you get.

I have a ASP.NET Core with Blazor website and I want to deploy it to Arvixe host. The website is very simple and contains only UI elements no database required. I published the website to a local file system and uploaded it using FTP to the Plesk.
When I am visiting the website, I receive this error:
500 - Internal server error. There is a problem with the resource you
are looking for, and it cannot be displayed.
I have tried to run it on the IIS and I received more details:
Configuration The configuration file cannot be read due to
insufficient permissions.
I tried to add IIS_IUSRS to the group and users for web.config but I am not able to find it because I am using a windows 10 connected to active directory.
Besides, I still don't know how to solve this problem at Arvixe. Does anyone know tips might help?
500 internal error is generic issue. Please kindly check the error message on the server and paste it here. Make sure that your provider has installed .net core bundled on their server and here are tutorial about publsih .net core using plesk https://windowswebhostingreview.com/how-to-publish-using-web-deploy-with-plesk-control-panel/. It should be working fine.
You need to give Full Trust permission (Read-Write-Execute) to your application folder and also to Application Pool and also check if the Runtime version supported by Arvixe matches with your Asp.net Core version.
Also enable the logs in web.config file by setting stdoutLogEnabled="true" to get detailed error so that you can investigate more about the error.
I'm using the web deploy API to deploy a web package (.zip file, created by MSDeploy.exe) to programmatically roll the package out to a server (we need to do some other things before we release the package which is why we're not doing it all in one go using MSDeploy.exe).
Here's the code I have. My question is really to clarify what is happening when this is executed. In the package parameters XML file I have the application name specified ("Default Web Site") but that's about it, there's no other params are specified in there. From testing the server it appears the package gets deployed successfully but my question is are any other settings on the server I'm deploying to getting changed without my knowledge, are any default settings published etc.? Things like security settings, directory browsing etc. that I might not be aware of? The code here seems to deploy the package but I'm anxious about using this on a production environment when I'm so unsure of how this API works. The MS documentation is not helpful (more like non-existant, actually).
DeploymentChangeSummary changes;
string packageToDeploy = "C:/MyPackageLocation.zip";
string packageParametersFile = "C:/MyPackageLocation.SetParameters.xml";
DeploymentBaseOptions destinationOptions = new DeploymentBaseOptions()
{
UserName = "MyUsername",
Password = "MyPassword",
ComputerName = "localhost"
};
using (DeploymentObject deploymentObject = DeploymentManager.CreateObject(DeploymentWellKnownProvider.Package,
packageToDeploy))
{
deploymentObject.SyncParameters.Load(packageParametersFile);
DeploymentSyncOptions syncOptions = new DeploymentSyncOptions();
syncOptions.WhatIf = false;
//Deploy the package to the server.
changes = deploymentObject.SyncTo(destinationOptions, syncOptions);
}
If anyone could clarify that this snippet should deploy a package to a web site application on a server, without changing any existing server settings (unless specified in the SetParameters.xml file) that would be really helpful. Any good resources on using the API or an explanation of how web deployment works behind the scenes would also be much appreciated!
The setparameters file just controls the value for the parameters defined in the package. A package might be doing much more than that. Web deploy has a concept of providers and any given package can have one or more providers.
If you want to make sure that the package is not changing server side settings the best approach you can take is to use the API but make the packages be deployed via Web Management Service. This will give you two benefits:
You can control what providers you allow through.
You can add users and give restricted permissions to them to deploy to their site or their folder etc.
The alternate approach is to:
In the package manually look at the archive.xml and look for the providers in the package. As long as you dont see any of the following providers that can cause server settings change such as apphostconfig or webserver or regkey (this is not a comprehensive list) you should be good. Runcommand is a provider that allows you to execute batch scripts or commands. While it is a good provider for admins themselves you need to consider whether you want to allow packages with such providers to run.
You can do the above mentioned inspection in code by calling getchildren on the deployment object you create out of the package and inspect the providers and the provider paths.
Our aim is to have Zero dependency from the client configuration files for WCF services.
we are using ConfigurationChannelFactory() to create the channel and specify the ConfigSettings.
ConfigSettings is loaded using the following code
ConfigurationManager.OpenExeConfiguration(ConfigFilePath);
So we have to provide the ConfigFilePath here.
we have both windows and web clients.
we have used below approaches to find out the path
AppDomain.CurrentDomain.BaseDirectory + "bin\\" + executingAssembly.GetName().Name + ".dll"
Web client : AppDomain.CurrentDomain.BaseDirectory gives root folder of the
web applicaton so its works fine
Windows client : AppDomain.CurrentDomain.BaseDirectory gives path upto Debug/Release folder
so, its throws error
Assembly.GetExecutingAssembly().Location
Web client : Assembly.GetExecutingAssembly().Location gives path to the ASP.Net temp.
files , where we dont have the config files. So its throws an error.
Windows client : Assembly.GetExecutingAssembly().Location gives the correct location,
so its works fine.
In order to make it works in web clients, we have to add the following key in client's web.config files.
<hostingenvironment shadowcopybinassemblies="false">
but it adds a dependency to the clients.
Can you guys please help me to find the path without worrying about the clients?
have you tried this? I used GetCallAssembly() instead of GetExecutingAssembly() as this lives in a utility class in our project.
public static string AssemblyDirectory
{
get{
string codeBase = assembly.GetCallingAssembly().CodeBase;
UriBuilder uri = new UriBuilder(codeBase);
string path = Uri.UnescapeDataString(uri.Path);
return Path.GetDirectoryName(path);
}
}
Could you just probe both paths? In other words, check the Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "bin") folder and if you can't find the config file in there, check the Assembly.GetExecutingAssembly().Location folder instead? Since you indicate that the first approach works for web but not Windows clients, while the second approach works for Windows clients but not web, go with both!
I've made my first little workflow in sharepoint and I am trying to access it from the outside using a ReceiveActivity. I have created a WCF svc file with
and created a website in IIS with the same application pool as the sharepoint site.
Now I can start the workflow from my doclib, but when I try to reach the ReceiveActivity like below, I get the following error: "the workflow hosting environment does not have a persistence service as required by an operation on the workflow instance".
I think it has something to do with not using the Sharepoint persistence service in my own WCF website, but I'm not sure. Any idea's on this one???
DoMyThingContractClient proxy = new DoMyThingContractClient ();
IContextManager contextManager = proxy.InnerChannel.GetProperty<IContextManager>();
IDictionary<string, string> context = contextManager.GetContext();
context.Add("instanceId", myInstanceId);
contextManager.SetContext(context);
result = proxy.GetMyMethod(tb1.Text, tb2.Text);
Have you created the SQL tables that host the workflows? The ones at C:\Windows\Microsoft.NET\Framework\v3.0\Windows Workflow Foundation\SQL\en? If you did, you now need to add the required tags to your config (your WCF's folder with the svc file in this case) as explained at msdn.
Edit after comments: try to run a Persistance Service in your code:
SqlWorkflowPersistenceService ps = new SqlWorkflowPersistenceService("Initial Catalog=SqlPersistenceService;Data Source=localhost;Integrated Security=SSPI");
currentWorkflowRuntime.AddService(ps);
I have a silverlight project that calls into a wcf service. Everything works fine on my local machine.
However when I deploy to a virtual machine, with the exact same query the wcf service returns, but the result is empty.
I've tried debugging, but have not been able to get it to break in the wcf service.
Any ideas what the problem could be, or how I could go about debugging it?
Thanks
I figured out what the problem is, but am not sure what the solution is.
In my silverlight project the wcf service I am referencing is http://localhost/.../SilverlightApiService.svc
I used fiddler on my vm to see the request that was made and instead of trying to contact the above service, it was trying to contact:
http:///.../SilverlightApiService.svc
So, for some reason my machine name is getting inserted in there instead of localhost. Any thoughts on this would be appreciated.
I had this exact problem when deploying to amazon ec2 - The machine name for the service was being returned in the wsdl rather than the dns.
There were a couple solutions (one involved creating static wsdl - yuck!)
But the other was creating a sort of factory pattern for the service

The slight downfall with this is that although it works - if you change the location of the server, you will need to remember to update your config - Which although isn't hard, it's easy to forget to do.
Can you give us a bit more information? What kind of binding are you using? What does the service config and the client config look like? Where do you get your data from that gets returned? Could it be the service on the VM just doesn't get any data? (e.g. queries a database that just doesn't have the data requested?)

I have had that happen before. I would try this. Set you start page as the web service file and run the app. Then set the start page back to your default page. Then update all the server references in your SL project. Recompile everything and republish. This has helped me a bunch of times in the past.
I figured it out.
Basically my machine name was hard coded in my ServiceReferences.ClientConfig file in my silverlight project.
What I had to do was specify programmatically what url to use for the service reference when instantiating my service client:
System.ServiceModel.EndpointAddress address = new System.ServiceModel.EndpointAddress(new Uri
(Application.Current.Host.Source, "../WebServices/SilverlightService.svc"));
ServiceClient serviceClient = new ServiceClient("BasicHttpBinding_IService", address);
I figured out what the problem is, but am not sure what the solution is.
