I'm trying to install powershell 2.0 on winxp SP3 with .Net Framework 4.0 installed on my machine but I can't install it. It asks for .Net 2.0. It makes no sense to me at all, since I have an upgraded version of such framework. Here's the full message:
"Cannot Install windows powershell v2 because it requires an updated version of the .Net framework. Please, install .Net framework 2.0."
Anyone can lend a hand here? Tnx.
You need 2.0 installed. 4.0 is a side-by-side version of the .NET CLR. It's not an in-place upgrade, so something that demands 2.0 specifically will not accept 4.0. Confusingly, .NET 3.5 SP1 is the latest version of 2.0 and is what you want.
3.0, 3.5 and 4.5** are not new versions of the CLR (.NET's JRE) and are more like libraries/service packs to CLR2 and CLR4.
** well, actually 4.5 is a bit muddier than that but the comparison is sufficient.

Just installed VS 2019 Pro on a new system. When I open a solution with .net 4.0 project, I get this error: Project Target Framework Not Installed.
When I choose download it, it goes here but does not have option for .net framework 4.0.
In project settings there is no option for .Net Framework 4.0 in targeting framework:
https://dotnet.microsoft.com/en-us/download/visual-studio-sdks?cid=getdotnetsdk
I have tried installing 4.6.2, 4.5.2, etc.
How can I get this project to open? It opens on my other machine. It has these options for Target framework in project settings:
Please don't say change the framework version, we need this older version for very old computers running XP and Win 7 that cannot be upgraded.
thank you
You have to go directly to their download site. As shown in another correct answer that was downvoted, it's still available even though it's past end-of-life.

You can package the install files with your app just in case, although most likely your installer will see that it's missing and download it anyway.
You can try downloading .Net 4.0 here: https://dotnet.microsoft.com/en-us/download/dotnet-framework/net40
Mandatory warning: Installing an old, unmaintained .Net framework comes with security risks. It's up to you to determine how much those Windows XP PCs are vulnerable and manage said risks.
i am new to development with Xamarian platform.Now i just want to run application to targetFramework 4.5. but there diff targetframework listed as below. how i resolve that please help me out.
See https://learn.microsoft.com/en-us/dotnet/standard/net-standard - in the table, note that .Net Framework 4.5 supports the newer net-standard up to 1.1. So choose .NET Standard 1.1. Or if you can require .Net Framework 4.5.1 and newer, choose .NET Standard 1.2.
Or better, whatever dependency is forcing you to use Framework 4.5, talk to the vendor, get them to rebuild for .NET Core 3.1 or the new .NET 6.
If you really must support .Net "Framework" APIs, see https://learn.microsoft.com/en-us/archive/msdn-magazine/2017/connect/net-introducing-the-windows-compatibility-pack-for-net-core, for a (no longer being updated) solution that allows your newer code to be "Net Core", yet work with legacy .net APIs.
Be aware all this is "legacy" - Microsoft's goal is to move everyone to .NET 6.
I have a VB.NET Windows Forms project targeting the .NET Framework 4.7.2:
I am trying to install Microsoft.EntityFrameworkCore.SqlServer of which the latest stable version is 5.0.8:
However after clicking install and accepting all terms I get an error:
Could not install package 'Microsoft.EntityFrameworkCore.SqlServer 5.0.8'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.7.2', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.
Does anyone know what the heck its moaning about version for?

EF Core 5 requires .NET Standard 2.1. .NET Framework only supports .NET Standard 2.0. So it will never work.
EF Core 3.1 is the last version to support .NET Standard 2.0, and so it's the last version of EF Core compatible with .NET Framework.
But .NET Core 5 supports Windows Forms.
So the options are:
upgrade everything to .NET Core 5
downgrade EF Core to version 3.1
switch from EF Core to EF 6, which is mature, stable and supports .NET Framework
The official documentation does not work.
Do I need VS 2017 Preview?! Or to restart my pc every time I install "Latest stable 2.2.3" SDK's? Perhaps its not so stable? Should I try 2.2.1 lol
VS 2015 will work up for up to .NET Core 1.1 (now EOL). VS 2017 will work for up to .NET Core 2.2. .NET Core 3.0+ requires VS 2019.
It's not clear what your exact issue is, but the process is basically this:
Download the appropriate .NET Core SDK version. Be careful because the SDK version is somewhat independent of the .NET Core version. Pay attention to specifically what version of .NET Core the SDK supports, not the version number of the SDK itself.
Edit your project file and change the target to the new .NET Core version. This will be the minor version, not patch releates. In other words, for any .NET Core 2.2.X, you'd use netcoreapp2.2 as your target.
That's it. After you save, any NuGet dependencies of your project, such as Microsoft.AspNetCore.App will update to the latest version within that target, i.e. 2.2.X. However, note that some packages may not always have new versions. Most of the major parts of ASP.NET Core, for example, change enough with each version that the NuGet packages get bumped as well. However, it is possible that you may still use a 2.1.X package if nothing changed in that for 2.2. In any case, you'll be able to see in Visual Studio if it's fully updated or not.
I would like to update my PowerShell from v2 to v3 but when installing, I get a message "Update not applicable to your computer". I tried to install the Windows6.1-KB2506143-x64 Windows Management Framework 3.0 - RC because I am practicing scripting but I can not use the scripts that I am learning in v2.
I do not have a virtual machine.
What is the problem?
Make sure you meet the system requirement of .net 4.0
Windows Management Framework 3.0 requires Microsoft .NET Framework 4.0"
The full release of PowerShell and the Windows Management Framework 3.0 has been released, I would suggest using it instead of the release candidate version you mentioned. You can find download links here: http://go.microsoft.com/fwlink/?LinkId=251995
The supported systems matrix is tighter than previous releases - you have to be running one of the following operating systems with the correct service pack level as well:
Windows 7 Service Pack 1 (32-bit & 64-bit)
Windows Server 2008 R2 Service Pack 1 (64-bit only, includes Server Core)
Windows Server 2008 Service Pack 2 (32-bit & 64-bit)
Also note, if you have any of the pre-release builds of v3 installed, you will have to remove them before installing the officially released version.
