I just installed visual studio 2010 but when i create a new project Framework 4 does not appear in the options for target framework. I know framework 4 installed correctly because the new app pools set to v4 were created in IIS. For some reason it's just not showing up in visual studio. I tried repairing dotnet 4 and reinstalling visual studio but still no luck. Anyone else have this problem or know how to fix it?
First of all you shoul use the .NET Framework Setup Verification Tool to check the .NET 4 have been properly installed.
I also recommend you to check the both products language, sometimes it could be the problem.
If everything is ok, i guess you have registry problem, so you would have to check the installation keys or use .NET uninstall tools.
More info:
Detection keys for .NET Framework 4.0 and Visual Studio 2010
Uninstall .NET Framework Tool
Visual Studio does not detect .NET Framework 4
Hope helps!
I had the same problem and it turned out to be that I needed the Microsoft .NET Framework 4 Multi-Targeting Pack. No other combination of actions would fix this.
I tried all the ways but no success,
According to this link,you can solve this problem by copy frameworklist.xml file from another computer and paste it in your system.
I had the same problem and I resolved it. I found out that there were no file FrameworkList.xml in folder C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\RedistList.
But I noticed this file in machine where .Net Framework 4 is accessible from VS
2010. Then I copied this file to my computer and restarted VS 2010. And .Net Framework 4
appeared from drop down list.
I attached frameworklist.xml file from my system :Download frameworklist.xml
Changes which lead to missing .Net4 problem:
1.
I changed some registry settings in
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
CommonFilesDir
CommonFilesDir (x86)
CommonW6432Dir
ProgramFilesDir
ProgramFilesDir (x86)
ProgramW6432Dir
All those were moved from C: drive to another drive (E: in my case)
2.
I changed the location of some user folders:
C:\Users\<name>\AppData\LocalLow
C:\Users\<name>\AppData\Roaming
Those were moved (via Properties->Path->"Move" button) from C: drive to F: drive.
After reverting 1. back to drive C:
and creating symbolic links in C:\Users\<name>\AppData to the new locations,
it worked again (note: I uninstalled VS before reverting the changes, and installed again afterwards)
(Create link with: mklink /d C:\Users\<name>\AppData\LocalLow E:\Data\LocalLow)
I can not say if both changes are really needed, because I changed both at once.
But finally it works again ;)

I'm seeing the same problem. We were using my build box to test installs of a WinForms app on a machine without 4.0. We bundled 4.0 in the manifest and the app works, Framework 4 Client Profile and Framework 4 Extended show up in add/remove programs, but there is still no 4.0 Framework in the VS2010 options.
BTW, reloading SP1 was no help.
I finally got this working by running the VS2010 setup in repair mode. I now see Framework 4.0 options in VS2010.
That was a long and tedious process and now I have to patch to SP1 again. MSFT should fix this behavior in a SP soon.
Had the same problem. Numerous uninstalls and reinstalls of visual studio 2010 and the .NET 4.X frameworks didn't fix it.
Manually uninstalling the "Microsoft Visual Studio Macro Tools" item and then doing a repair install of VS2010 seems to have done the trick.
I had the same problem this week and it got resolved by installing Visual Studio 2012 RC.
Removing and reinstalling .NET Framework 4 didn't help and I couldn't reinstall Visual Studio 2010. After installing the 2012 RC the Framework 4
I had installed .NET 4.5, which ended up breaking something, so decided to uninstall. VS 2010 could not longer see .NET 4.0. I tried using the .NET cleanup tool and reinstalling, but no go.
Eventually what worked was what is posted at http://social.msdn.microsoft.com/Forums/eu/netfxsetup/thread/3dede142-82ce-430c-bbe6-d824f0fb94a4. I installed Windows Phone Developer Tools (http://www.microsoft.com/en-us/download/details.aspx?id=13890) up until the multi-targeting package, at which point I canceled installation.
You can reinstall the targeting pack using this command, this solved my issue:
Microsoft .NET Framework 4 Multi-Targeting PAck
WCU\MTPack
COMMAND--> NetFx_DTP.msi EXTUI=1 /log "%TEMP%\dd_netfx_dtp.txt"
I think it's because you installed higher version of .net framework, such as .net framework 4.6, Which caused the mistake of missing .net framework 4.0.
For me using Arash's fix worked "there were no file FrameworkList.xml in folder C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\RedistList".
I noticed I had other .NET versions and just copied the FrameworkList.xml from one of those to 4.0 RedistList folder and it worked.
Problem:
VS2010 ->Right Click on Project -> Property Pages - > Build->Target Framework
is showing up to .NET 3.5 only. I have installed up to .NET 4.5 framework.
Solution:
I tried many solutions and decided to take a drastic step to format. The following way I got the solution without formating o/s.
Removed all .NET installations
Installed one by one from 1.0 to 4.6 with sps available.
VS2010 setup with repair option selected.
Opened vs2010 project and .NET framework up to 4.0.3 found in the list.

It's weird.
If I create a new project and choose DotNet 6 framework by Visual Studio 2022. I will get the NETSDK1045 error code.
But create a new project from the console, everything is Ok.
Run dotnet --list-sdks and see if the expected .NET6 version is installed.
My guess is that you might have x86 issue. If you have installed x64 version, install x86 version and vice versa and test if the issue is gone.
You can also try to repair your VS 2022 instance and/or upgrade to latest official version.
There is also a small probability that you select a project type that does not supports .NET 6 (for example .NET Framework Web App project type).
Also you may check your path contains the dotnet folders in the correct order for your architecture.

VS2017 : Target framework drop down does not show .NET Core 2.1 option
I'm using Visual Studio 2019 and just created a new .NET Core 3.1 web api project.
I noticed, that an option "use remote machine" is missing from the debug tab of project's properties.
However, when I open my old project, created in older versions of VS using .NET Core 2 (and then migrated to 3.1) - the option is present.
I've only recently started needing it and this inconsistency is strange to me.
This ticket on Microsoft website https://developercommunity.visualstudio.com/t/use-remote-machine-option-in-debug-settings-is-not/757921 suggests that it should be fixed in the latest version of VS, but I use the latest version and the problem still remains.
I figured it out, was my mistake. I needed to explicitly set launch option to executable. Then it becomes available. I should close the question.
Trying to run an old project in Visual Studio 2015. It was created in 2012 or 2013, I cannot remember which. I have uninstalled both programs as I was running out of space, and i think that is what caused this. I get the following options:
And I do not want to change the target, so clicking on the second option brings me to https://www.microsoft.com/net/targeting which I can't seem to find anything there that remedies the situation. Is there a way around this without reinstalling the old version of Visual Studio again? Will that even fix my problem? Thank you.
Just Reinstall Visual Studio. When you uninstalled previous version it caused this problem.
You could try doing a repair reinstall of Visual Studio 2015.
Another point to consider is that Windows 7 (the oldest version of Windows still supported by Microsoft) includes a Windows Update for the .NET Framework v4.6.1 categorized as an "Important" update. I have not confirmed with Windows 8, but I suspect it, too, includes a similar update. Windows 10 comes with .NET 4.6 to start with. That means that any up-to-date supported machine today will be able to run apps targeting any .NET version up to and including 4.6. I recognize that there may be other reasons to continue targeting an older .NET version, but I bring this up just in case the concern is support on client workstations.
Downloaded and ran SQLite setup.
Added dll reference to my project
In Server Explorer, added new connection, clicked 'Change' for data source and SQLite was one of the options.
Connected and used my tables.
Then...VS 2010 crashed.
When I reloaded my project, my connection wasn't in Server explorer, so tried to add it again.
SQLite was not in the list of options.
Re-ran SQLite setup, deleted/re-added reference, restarted project...still no SQLite in the list.
How can I get SQLite connected in Server Explorer???
This is an old question but for someone, like me, who finds this before there is a newer answer:
missing SQLite data provider in VS 2013
Basically for the latest versions of SQLite you can download an installer that includes the components
http://system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki
Choose the right setup for you, for me was:
Setups for 32-bit Windows (.NET Framework 4.5.1)
sqlite-netFx451-setup-bundle-x86-2013-1.0.94.0.exe
I have Windows 7 x64 with Visual Studio community 2015 and this solution worked for me.
Basically you need install SQLite bundel and check the "Install the designer component for Visual Studio 2015".
If you have different version from 2015 (2010/2013 etc.) just search for the bundle the suits your version.
1. Go to:
http://system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki
2. Download "sqlite-netFx46-setup-bundle-x86-2015-1.0.104.0" (download the most updated, this is the one I found).
Or by a direct link:
http://system.data.sqlite.org/downloads/1.0.104.0/sqlite-netFx46-setup-bundle-x86-2015-1.0.104.0.exe
3. Run the setup:
4. Result:
You can find installers on the System.Data.SQLite Dowload Page. Seteps files will suit your needs.
For example, the description of the Setups for 64-bit Windows (.NET Framework 4.0) states:
This setup package features the mixed-mode assembly and will install all the necessary runtime components and dependencies for the x64 version of the System.Data.SQLite 1.0.81.0 (3.7.12.1) package. The Visual C++ 2010 SP1 runtime for x64 is included. The .NET Framework 4.0 is required.
None of answers worked for me. in addition to #E235 answer
i added sqlite nuget package
updated ef to 6.1.3
then it worked i was able to see datasource
I've been upgrading some Silverlight 3 apps to Silverlight 4 in Visual Studio 2010. My Silverlight 3 apps open fine in Visual Studio, but SL4 apps don't, with the following error:
C:\Path\To\MyProject.csproj : error : Unable to read the project file 'XNTVOD.AdminClient.csproj'.
C:\Path\To\MyProject.csproj(593,3): The imported project "C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v4.0\Microsoft.Silverlight.CSharp.targets" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.
I had a problem with older VS Silverlight components and recently uninstalled most of the SL components, and right now in Add/Remove programs I have:
Microsoft Silverlight
Microsoft Silverlight 3 SDK
Microsoft Silverlight 4 Toolkit April 2010
The <import> declaration looks like this for the SL4 project:
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\Silverlight\$(SilverlightVersion)\Microsoft.Silverlight.CSharp.targets" />
That folder, C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v4.0 only has two files in it:
Microsoft.Ria.Client.targets
Microsoft.Ria.Client.VisualStudio.targets
What Silverlight development component am I missing in particular? I see a bunch of different options, from Silverlight 4 SDK Beta to VS Tools for Silverlight 4 and a bunch of others. I don't want to install stuff that will get me right back to the situation I had before this one with outdated components.
Looks like this is the missing piece...
Silverlight 4 Tools for Visual Studio 2010
The file that's missing ships in the Silverlight 4 SDK. You can either install just the Silverlight 4 SDK, or re-install the entire Silverlight 4 Tools for VS2010 package (which will re-install the developer runtime, SDK, a hotfix for VS2010, the Silverlight 4 Tools package, and WCF RIA Services).
You may get this with Silverlight version 4 projects when trying to open in version 5 if version 4 bits are not on that machine. What has worked for me (after several hours of trying everything) is to edit the csproj file and change the silverlight target version
<TargetFrameworkVersion>v4.0</TargetFrameworkVersion>
From 4 to 5
This worked well for me...also had to install Silverlight 4 Developer runtime
Afer many tries, what worked for me was:
1. go to add or remove programms
2. remove all silverlight versions installed (4, 5 or even if version is not specified remove it too!)
3. install Silverlight 4 SDK
4. install Silverlight 5 for developers
Finally opened the project in VS 2010 SP1
A previously working installation can break when you install a new version of TFS on the server (or whatever it was that messed with my MSBuild).
My 'targets' files had disappeared from C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v5.0 on Server 2012 and reinstalling the tools.
I believe it may be possible to just copy the targets files from another machine but not 100% sure.
