I have built a C# WPF Application in Dot Net Framework 3.0 and published thru Click Once Application via localhost IIS in my system. My system placed in FileServer1 Domain and all the systems under FileServer1 can able to install the application. But we can not able to install it under different domain FileServer2.
While clicking the Install button, it will show that Installation file was missing. Please help me out how to proceed with this issue.
While publishing the file, I have given as http:\10.xxx.xx.xx instead of localhost. Now its working in all the domains.

We're making a new application using WPF .Net Core. To use the auto update function we decided to pack it with the MSIX Packaging Tool as a UWP App in VS2019. I was able to host the appinstaller File on an IIS and to Install the App over a link to that file over the web. Auto updating is also working fine.
Now to the problem:
When I run the installed App it's icon is not showing in the task bar but it is shown in the Task-Manager using a lot of cpu. In the Process Monitor it shows that the App tries to access its dependencies (like PresentationFramework.dll) but is not successful as the result is always "File locked with only readers". The DLL itself is present in the WindowsApps/xxx/ Path. Also I can not start the EXE manually as my user do not have the rights. What am I missing here?
Edit: Also I realized now that my app is only starting as a background process in the task manager and not as an app. When I go to the app directory under WindowsApps/xxx/MyApp I can not start the EXE directly because of no rights as mentioned before. But when I copy the whole folder I can start the EXE, the GUI appears and the app is an app again in the task manager.
We found an answer. As the GUI is a WPF .Net Core Project and we make the setup with a Windows Application Packaging Project to generate a UWP App from it the technology used seems to be the so called Desktop Bridge.
In the process monitor it seems that it tries to access the files under the correct path but somehow it does it not in the right way as long as the application path is not set correctly in the WPF Projects App.xaml.cs.
To fix this use the solution from Andrew Leader
I have a client WPF app that uses NativeMessagingHost feature in Chromium browsers.
I've packaged my WPF app into Windows Store Package (.appx) via Desktop Bridge using VisualStudio to publish it in Windows Store in the future.
My app works correctly from Store package. Creates ChromeManifest.json file. But cannot link manifest to chrome NativaMessagingHost name via registry.
Desktop Bridge Apps cannot modify HKCU\Software\Google\Chrome\NativeMessagingHosts\. This is allowed but it's modified in sandbox (proof), so chrome do not see the registry value.
Result: chrome extension cannot find NativeMessagingHost.
NOTE: If I change the registry value to valid value manually via regedit.exe - everything works fine!
So, is there any way/workaround to modify registry key or link ChromeManifest.json from Desktop Bridge App? Maybe on package install?
This is not allowed from a Store app. You would also need to take care of the Chrome-specific registration when the user installs/registers the app as Chrome extension.
I have developed a WPF application and deployed it using Click Once Deployment. I installed it on another pc it works fine but the problem is that the application's root folder is being created in a temporary folder in app data/local. I want to give user the flexibility of installing the software wherever he/she wants. How do I do this?
You simply can't change the installation folder using ClickOnce. If you want to do this you need to choose a different installer technology.
ClickOnce application require no administrative privileges and are always installed per user in the user application cache.
It seems that DNN is undergoing an upgrade and I cannot access the forums or many of the docs. Needing an answer soon, and Google providing too many varied types of hits (none of which are helpful or most of which post to the DNN site that is undergoing that upgrade), I had a few questions about setting up DNN.
First, I am coming from Orchard. There I was able to use Webmatrix - I downloaded the web version, opened as administrator, created modules, messed with themes, etc. Using the Orchard Docs, I was able to set up a multi-tenant site and run it on local host (IIS express through Webmatrix) - this included modifying the host/config files to view the multi-tenant sites. I could then publish to my own server running IIS 7. On the server I set up the landlord site then bound the tenants with no problem.
Being new to DNN (and things not being readily available at the moment on their site), I was hoping I could get some guidance on how to set up DNN similar to what I did with Orchard.
First question is obviously whether or not that is possible (i.e., no IIS, only IIS Express (Webmatrix) on my local machine).
Here would be my other questions:
If I can run it locally, can I just download the 7.1.0 new install package, and open Webmatrix (as Admin) on the folder I unzipped it in?
Assuming I just "Run" the website, I will then set up the "Landlord" instance of DNN on the following screens, correct? (i.e., where it asks for credentials and what DB setup I can use)
Can I then go ahead and create sub-tenant sites (alias/portal)? If so, do I go about manually updating my host/config files to run those tenants (depending on the port)?
Assume all of the above is correct, do I have to "reinstall" the 7.1.0 package on my webserver, or will a simple publish from Webmatrix do (with the proper credentials in Settings)? If so, I can handle pointing to the landlord on my server and then binding my subtenants in IIS.
Sorry for the n00b questions. Thanks!
On the Download page on dnnsoftware.com, there's a link to click which will start the install process within WebMatrix: http://www.microsoft.com/web/gallery/install.aspx?appsxml=www.microsoft.com%2fweb%2fwebpi%2f2.0%2fWebApplicationList.xml&appid=106
When you create a new portal, you can specify that it uses a URL which is a subdirectory of the current URL (i.e. a child portal alias), so that you don't have to use different ports. I'm not especially familiar with IIS Express, so I would expect that you could point multiple ports to the site, and map those as different portal aliases, but not sure exactly how you could do that, if you don't want to make use of child portal aliases.
To publish a site, you should just need to push the file system and database, and setup IIS.
I just lost 5 hours looking for a answer which i haven't been able to find :p
First, I'd like to force a trusted application (i need to access the file system) to display into the browser. Based on what i found on google a trusted application must be installed and launched as a desktop application (also called out-of-browser application).
So, i want to have an installed application on the client side but meanwhile, the user must also be able to start this same application into a browser window when he goes on my web site. Is this possible ?
Second, I'd like to give to the user the possibility to start the application from the browser. To be clear, the application is installed on the client computer but i want a button on my web site which starts the desktop application. How can i do that ?
Thanks
The answers are sort of and no.
Yes you can run an application that has been installed on the client also in the browser. However, not all of the installed application features will be available. Anything that requires elevated trust will not work inside the browser.
No you can't launch the installed application programmatically from within code running in the browser. The best you can do is display a polite message to the user to the effect that they have this app already installed and in order to access all of its feature they will need to launch it.
Yes, it is possbile since Silverlight 5, see my answer on silverlight-4-elevated-permission-inside-the-browser
