.NET framework version missing

Question

.NET framework version missing

Vasiliki Anagnostatou 0

Hallo,

I am quite new to VS.

I installed the Community version 2022 recently but I cannot run my script.

I get the error which I copied here below. I checked in my registry editor and I can see that I have the version 4.8.04084 (even though in the warning the "0" is missing). I am not sure what is going on there. I have intalled the .NET framework 4.8. Do you know what it might be happening ?

Severity Code Description Project File Line Suppression State

Error MSB3644 The reference assemblies for .NETFramework,Version=v4.8.4084 were not found. To resolve this, install the Developer Pack (SDK/Targeting Pack) for this framework version or retarget your application. You can download .NET Framework Developer Packs at https://aka.ms/msbuild/developerpacks C:\Users\Elekta\Sample_Scripts\AutoDicomImport\AutoDicomImport.csproj C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Current\Bin\amd64\Microsoft.Common.CurrentVersion.targets 1241

Hallo Jiachen,

It seems like the VS is now successfully installed, however, I still need to test that by using my scripts to see if finally everything works. Could I contact you again in case I encounter installation issues ?

Thanks very much,

Hi @Vasiliki Anagnostatou ,

The error message suggests that you can resolve this by installing the .NET Framework 4.8 Developer Pack (SDK/Targeting Pack) for the specific version mentioned.

You can download it from the link provided in the error message: https://aka.ms/msbuild/developerpacks

Best Regards.

Hi Jiachen,

Thanks very much for your message.

I believe that my installation includes that. I did an offline installation by using the command vs_enterprise.exe --layout c:\localVSlayout which should download a complete package. Is that right ?

Hi @Vasiliki Anagnostatou ,

Use dotnet --list-sdks in the command line to check if the .Net Framework 4.8 SDK is already installed.

Hi Jiachen,

I can see that I have the 7.0.400 [C:\Program Files\dotnet\sdk] version.

Is that the 7.0 .NET version ?

Actually my scripts require a .NET greater than the 4.5 version. I guess that with this version they would work too.

In order to try whether my scripts work with the existing version, do I need to define the version within the app.config file ?

I now have: <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />

Do I also need to define the version I have within the Visual Studio itself ?

Best Regards,

Vassia

Hi @Vasiliki Anagnostatou ,

. NET and the .NET Framework are different, so your .NET 7 SDK will not work for your application, consider installing it. NET Framework 4.8 SDK.

You can also consider install it from Visual Studio Installer.

Hi,

It seems that I had this one installed. I also re-installed it. However when I click the command dotnet --list-sdks it still does not show me the 4.8 (it still shows me the 7.0.400 only. Is there another way to see if I have installed the individual components 4.8 SDK and targeting packs ?

I also re-tried the script but I now get only the warning:

Severity Code Description Project File Line Suppression State

Warning MSB3270 There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "MonacoScripting", "x86". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project. C:\Users\Elekta\source\repos\MonacoScripting Console App1\MonacoScripting Console App1\MonacoScripting Console App1.csproj C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Current\Bin\amd64\Microsoft.Common.CurrentVersion.targets 2364

Let me know what you think.

Hi @Vasiliki Anagnostatou ,

Try modifying your project's Target CPU, and then rebuild your project.

Project Properties → Compile → Target CPU.

Hi Jiachen,

Thanks very much, I did that on my Console Application (it should be on "Build") and I now cannot see the warning ("MSIL" and x86 incompatibility).

I have some scripts to run (which I should run on "Release"). However, when I open my Folder (I launch the Folder from the installer), I do not see the "Debug" or "Release" Buttons on menu, and I see the following (I attach the screenshot).

I am supposed to see the "Release" Button and "Any CPU" (next to) it according to the instructions, but there are not there. Is it a matter of visualization or could something still be missing ?

Additionally, do I have to somehow connect my Console application to this script ?

Thanks in advance,

Vassia

I forgot to add that if I click on the "Play" Button then I get the following error message

Severity Code Description Project File Line Suppression State

Error MSB3644 The reference assemblies for .NETFramework,Version=v4.8.4084 were not found. To resolve this, install the Developer Pack (SDK/Targeting Pack) for this framework version or retarget your application.

Even though I installed the 4.8 SDK and targeting pack (screenshot), I still cannot see it when typing the command dotnet --list-sdks

Thanks,

Hi @Vasiliki Anagnostatou ,

Please check if your application's target framework is set to .NET Framework 4.8.

Hi Jiachen,

Thanks very much.

I think I was missing the .sln file (provided together with the script). I was only opening the script therefore the buttons "Release" or "Debug" were not appearing.

Do I only need to open the .sln file with visual Studio, right ? And not just the script ?

Hi @Vasiliki Anagnostatou ,

Yes, .sln file allows Visual Studio to recognize it as a Visual Studio solution.

Hallo,

Sorry, I am not sure if you received my last answer, I mentioned that I had to do an offline installation and used the following command

vs_Community.exe --layout C:\localVSlayout

I believe that this command should install all packages (including the .NET. )

Is that right ?

Do you know how can I see which version of .NET have I installed ?

Thanks in advance,

Vassia
