I am developing a winform app on VS2010 on my home PC . To test it on the computer of my university, I just changed its Target Framework from .NET Framework 4.0 client profile to .NET Framework 2.0. ( .NET Framework 4.0 client profile was selected by default). After this I run (debug) my app on my home PC and it runs slowly so i decided to change its target framework to previous one.
After changing target framework I cant debug my app ( upon pressing F5 "Build succeeded" is shown on the most left bottom). Although i can run my app by pressing ctrl+F5 but cant debug. I have restarted my VS 2010 but no success was achieved.
Check the msdn link,

I think, VS 2010 includes only the .NET Framework 4. To target earlier versions of the .NET Framework, you need to install the appropriate framework. If you change it to Framework 2.0, you need to install it to work properly.
Let us know, if this solves.
cheers

I am trying to build MSIX setup for my WinForms application built on .net6. I want to give auto-update feature when the user clicks the "Update" button. I think originally developer didn't have control over updating MSIX and there was only way it was updated automatically when the application is restarted.
But there is a recent article on taking full control over MSIX updates I tried to follow it but I am facing the exception 'System.InvalidOperationException' while running the below line of code.
Package package = Package.Current;
I am using visual studio 2022 & WinForms application running on .net 6. I have kept other configurations as described in the above article but it is not working as expected. (I have tried in .net core 3.1 and it is working with it)
Package.Current only works in a packaged context, so you need to make sure to actually debug/launch the packaging project. An InvalidOperationException indicates that you are running your project unpackaged.
Make sure to select "Set as Startup Project" on the packaging project, likely named "MyApp (Packaging)" in the Solution Explorer. Then you can launch/debug your project as you normally do.
I recently upgraded my WPF app from .NET framework 4.7 to .NET 6. But when I try to deploy my app on my client's computer, my app won't start because this new computer don't have .NET Desktop Runtime installed. So, how do I detect the absence of .NET runtime and promt a window asking the app user to download .NET runtime? Just like the below picture:
I'm not using any installer, just copy and paste my build folder to the new machine.
I remember that when I was using .NET framework, if the runtime was missing, the Windows system would automatically promt a window ask me to download the runtime.
Obviously your .NET 6 app won't be able to start and even less detect something unless the .NET 6 runtime is installed on the machine where you run the app.
To overcome this issue, you could bundle the .NET 6 runtime with your app by publishing it as self-contained:
dotnet publish -r win-x86
You will then copy the entire output of the publish folder, which includes the necessary .NET assemmblies, to the target machine.
Please refer to the linked docs for more information.
I am publishing a WPF (.NET 6) application with the following settings:
This works, but if my users want to launch the exe-file on their own PC they get an error message: ".NET 6.0 Runtime is not installed".
This makes sense to me because .NET 6 is quiet new.
But even after installing the runtime they still get this message (after restarting their PC).
Only if they install the SDK they can launch the app.
But the SDK should only be fore developers?
Am I publishing my app in the wrong way? How can I run .NET 6 apps with only the runtime installed?
My users are all using Windows 10.
I could resolve my issue with deploying my app as "Self contained". Now the framework is inside the published files.
Everything fine...
However, strange that the initial way did not work. :(
Make sure to get the .NET Desktop Runtime 6 from the Microsoft download page:
I am trying to build a setup-msi using visual studio for my wpf application.
The issue i am facing is that i force primary output from wpf project to the setup project
and the dependencies are calcaluted automatically.
I run the msi locally (on the machine i built the wpf app) and everything works fine.
The problems start when i try to install it on different machines.
On other machines i run the installation process and it finishes justfine
but when i try to run the application i get exceptions about assemblies that could not be found.(e.g System.Web , Version=4,0,0,0 could not be found etc)
I really suck building setup projects but can anybody give a hand?
P.S.: I also tried installShield... same results.
I would guess that the target machine only had .NET Framework 4.0 Client Profile installed. System.Web is in .NET Framework 4.0 Extended, which is installed with the full 4.0 Framework but not with the Client Profile.
Are you bootstrapping .NET 4 in your setup?
Check for the presence of "Microsoft .NET Framework 4 Client Profile" and "Microsoft .NET Framework 4 Extended" in Add/Remove Programs (XP) or Programs and Features (Vista/7) on the machines where the application ran fine and those where it gave that error.
Edit: .NET Framework Deployment Guide for Developers. That should help you figure out how best to deploy it.
I have deployed website using silverlight 3.0.40307.0. It is working perfectly in Local IIS. But when client will installs the newer version of silverlight like 3.0.40626 or higher, It wan't be able to view website.
How to get silverlight 3.0.40307 (old version of 3.0 beta)?
What is the possible solution to deploy silverlight website on IIS?
What silverlight component should be installed on server to view silverlight application on browser?
Can we install silverlight TOOL without VS2008+SP1? if yes, then how?
You need to upgrade your version of Silverlight to the released version. You can't expect users to run beta software because you would be forcing them to use software that is known to contain defects.
You need to download the latest version of the SDK and templates from here.
Clients need only the Silverlight runtime plugin for their browser. There's no way you can enforce the client to install the SL 3 Beta version of the plugin you want; and even if you do, there's no (easy) way to prevent it from self-updating to the RTM version. Not only that, but asking clients to install a Beta version of a released product is a security threat for them.
There's no official way to get the SL 3 Beta runtime installer.
An SL app is a client-side code; on the server side you only need standard IIS that serves HTML with an tag and the .xap file for the SL application.
There are no SL components required to be installed on the server for the client to run the SL app.
You can't install the Silverlight Visual Studio Tools without VS2008 SP1 - as their name suggests, the tools are intended to integrate with VS. However, you can install the SL SDK and build SL applications without having VS2008 SP1. (Alternatively, you could use MonoDevelop/Mono/Moonlight to develop SL applications)
If you have deployed your silverlight app that is compiled with Silverlight version 3.0.4.0307.0(i.e. Silverlight Beta), your app may work perfectly for the users with Silverlight 3(RTM).
However, if those visitors come across your silverlight app who doesn't have Silverlight installed at all(or maybe lower than Silverlight 3 Beta), they will be prompted to download Silverlight to view your app.
Once they wish to download Silverlight runtime by clicking on the "Get Silverlight" button, visitors will be redirected to Silverlight download location, and the most important part is
**They will get a message explaining that this app is made with Beta version of the Silverlight.
So this may hamper thier experience and impression about your silverlight app and because of this very few people can get to your app correctly **
It is my suggestion that you try to compile your project with Silverlight 3 as early as possible .
Regarding 2nd question What is the possible solution to deploy silverlight website on IIS?
Here is the Answer : You'll need to register the MIME types for xap on your server.
