'.NET SDK's Not Installing Correctly

I am getting an issue with installing the .NET SDK, at first when I went into visual studio 2019 it said that I was missing the dotnet runtime sdk so I installed it like it asked and restarted my computer. I then went on to visual studio 2019 again, and the same issue arose, I went into my command prompt and typed dotnet --list-sdks and it displayed no sdks. I have all of the runtimes installed, but it says No SDKs were found. image . I tried re-installing the sdks but the same problem stuck. I even went as far as to re-install IIS. I can't do anything without this being fixed please help soon!

Before you try a manual install, I'd check if the Path in the system's environment variables is correctly configured for your system.

Given that there's always one shared host that moves forward, it will either pick the x86 or the x64 version on your machine. This issue of not picking the right one might happen if you install multiple/different versions.

Run the where.exe dotnet command to see where the host is looking for the SDK (it's the first entry returned). If you're on a x64 machine, you want to have C:\Program Files\dotnet listed first.

If it's not, edit the Path system's environment variable to have the location you want showing up higher. Doing that should fix the issue of the SDK versions you installed not showing up when you run dotnet --info.

See The latest installed .NET SDK not found for complete instructions.

Answer above by Maira is correct and fixed the issue however for those that need a little help go to start menu, type "path" and select "Edit the System Environment variables". When that opens, under the "Advanced" tab click "Environment Variables". Under System Variables find the "Path" variable and click "Edit". Find "C:\Program Files\dotnet" and click "Move Up" so that it is above the (x86) variable.

dotnet do not seem to match well with SDKs / runtimes with 32-bits and 64-bits. If you have both variants and want to only use the 64-bits (or generally, cant list up any SDK-s), you can try this :

  • Inside folder : C:\Program Files (x86)
  • Rename folder 'dotnet' to 'dotnet_x68'
  • Inside a shell (remember to either run command 'refreshenv' from Chocolatey for example to refresh your environment, if you have choco installed.. )
  • Enter now this command :
  • dotnet --info List of Dotnet Runtimes and SDKs
  • Also list the SDKS :
  • dotnet --list-sdks
  • List sdks

This fixed up my development environment. Note that if you want to use dotnet against x86 system, you might consider to instead uninstall x64 variants of dotnet runtime and sdks as dotnet do not seem to work very good from command line with a mix of them both (and avoid renaming the x86 folder of dotnet of course as suggested above.

I found that I had two program files, One called Program Files (x86) and one called Program Files. I went to Settings, About and looked at my System Type. I have a 64-Bit operating system and so I went into Program Files (x86) and found another dotnet folder. I deleted the dotnet folder and restarted Visual Studio. It Worked after that.
