Hi @Polachan Paily ,

The following methods will help you, you can try it.
1.Clean-up obsolete .NET Core versions: Go to Control Panel and uninstall previous .NET Core SDK/Runtime versions (as long as you don't use them anymore).
2.Create a Global.json file: Add a new global.json file to your project's root with the following content (replace the .NET Core version build with the one you want to run the project with):

   { "sdk": { "version": "2.0.5" } }  

3.Rename the SDK reference: Open your .proj file and replace <project sdk="Microsoft.NET.Sdk.web"> with <project sdk="Microsoft.NET.Sdk"> .
4.Check your PATH: Verify that both C:\Program Files\dotnet and C:\Program Files (x86)\dotnet are in the PATH environment variable.
