Check your .NET component very carefully, I found my .NET CLI component at the very end of .NET framework component, remove it and remove the RC2 component and re-install the RC2 component, when running HelloWorld sample app, delete the old "hwapp" if you have it, create a new one and follow the steps on MS RC2 download page will work.

Global.json..... Version needs to match, sdk installed

I got these error after I uninstalled old version of SDK. For me removing SDK folder from program files solved it.

The folder in 'C:\Program Files\dotnet\sdk' for the particular SDK version didn't get deleted when I uninstalled SDK. I think I saw error 'file in use' when I was uninstalling.

It works fine after deleting the folder. For example, I deleted folder 'C:\Program Files\dotnet\sdk\2.1.300'. This was folder for RC release. I think 'dotnet' cli looks for dotnet.dll in SDK folder.

The sdk dll file may be corrupted or lost you can try this on debian to reinstall dotnet core sdk sudo apt-get install dotnet-sdk-2.1 or for latest version see https://www.microsoft.com/net/download/linux-package-manager/debian8/sdk-current

This is still a problem. Removing 2.200-preview via Programs/Features does not remove the folder in ProgramFiles/dotnet/sdk. I had to remove the folder manually for this to work.

[robert-skarzycki]

FYI - same thing after uninstalling preview on 3.0.100 - I had to manually remove preview version folders from sdk folder.

[n-develop]

I had the same problem after uninstalling SDK 2.2.401. Removing the empty folder made it work again.

[suadev]

Same problem for removing sdk version 3.0.100

Yes after removing the folder of uninstalled version, solved the problem. Thanks

I was getting same error and was unable to delete the folder as it kept saying its being used. Killing dotnet process from Task Manager did not help. But the same from powershell helped free it and I could delete it.

gps -Name dotnet
spps #id_of_dotnet process
ri 'C:\Program Files\dotnet\sdk\5.0.100-rc.1.20452.10'

Same here. Uninstalled 5.0 rc, and folder is left there and I can't delete it. And no dotnet process is running, so it's held by something else. 😠

Since the release of netcore 3.0 I only used release versions of VS 2019 and now that 5.0 SDK introduces breaking changes for projects targeting 3.1.x I wanted to apply a global.json file but only got DotNet.DLL not found.

No wonder none of 3.1.400, 3.1.402, 3.1.403 work:

Since the release of netcore 3.0 I only used release versions of VS 2019 and applied updates every 2 weeks or so.

I got this, in my case I had: C:\Program Files\dotnet\sdk\5.0.103 C:\Program Files\dotnet\sdk\5.0.201

The earlier was empty and removing it fixed it. This was giving errors both in the command line and in VS.

[springy76]

Happened since with each new NET SDK VisualStudio installs. Each time some empty Razor sub directory is present.
