I have created my windows application using .net 3.5 framework and now updated to .net 4.0. After upgrading to 4.0 my application is removing registry entries.
What I need to do to resolve this issue?

What is the correct pattern/ what packages to use for WPF click once deployment in .net core 3.0( earlier versions are okay too)?
I am currently migrating a WPF app from netframework 4.8 to .net core 3.0. I have been using click once deployment in in the previous version. I was using System.Deployment package which is not supported in .net core. Is there any substitution for the package and what is the correct way to implement click once deployment in .net core and is it even possible? Should it be done using MSIX, if so is there any good guide about MSIX click once deployment?
Support for ClickOnce is now available in .NET Core 3.1 and higher (you need Visual Studio 2019).
Source Microsoft Docs:
Starting in Visual Studio 2019 version 16.8, you can use the Publish tool to publish .NET Core 3.1, or newer, Windows Desktop applications using ClickOnce from Visual Studio
As we know,.net core 3.0 support WPF project now.
And now I want to migrate my .NET Framework WPF project to .NET Core.
I installed Visual Studio 2019 Preview 2.2 & .NET Core 3.0 Preview 2. However, it seems Visual Studio 2019 has no way to migrate old the WPF project to .NET Core. I googled and found nothing about this.
Is there any way for me to migrate it or I can only rewrite it all by .NET Core? Thank you.
Do you know if Windows Server 2012 can run .NET Framework 2.0 applications?
So far I tried to install .NET framework 2.0 (for running an application that's based on this version) but it fails.
Microsoft website informs that WS 2012 includes .NET FW 4.5 or 4.5.1 but does not say about .NET 2.0
Do you know?
Thank you
Yes it does, but you have to install the feature.
Click the start button, type Windows Features and click Turn Windows features on or off. That should bring up the Server Manager and automatically after a second or two bring up the "Add Roles and Features Wizard." Click next until it gets to Features. Check the box at the top that says ".NET Framework 3.5 Features." This includes .NET 2.0 and 3.0.
I have an existing project built in Visual Studio 2012 with VC++, which works fine on Windows 7 or higher versions. But when running on Windows XP, it gives an error that the application needs .NET framework v4.0 or higher to run. I am unable to install .NET Framework v4.0 on that system either.
So, the problem is that I want to downgrade my project's Target Framework Version, and I could not find any way to do it in Visual Studio 2012 - Windows Forms Application project.
Is there an alternate or better solution?
You must compile two applications, one for Windows 7 or higher and one for lower than Windows 7.
For changing your application .NET Framework follow the below address
[On Menu Bar]
Project -> "Your Application Name" Properties -> Application
And change
"Target Framework"
Do I need 4.5 hosting for a Visual Studio 2012 project? I am using 2012 SQL Server as well. Does this require 4.5 framework for hosting?
It depends on the settings of your project. In VS2012, in the Project --> Properties dialog, you can set the target framework version. Depending on what you're doing you may or may not need the full 4.5 framework.
No you do not require .NET 4.5 - You can choose what version of the framework you need by going to Project -> Properties. SQL Server seems to rely only on .NET 4 (NOT .NET 4.5)
No, unless your project is using .NET Framework 4.5
