We have downloaded and run DotNetCore.1.0.1-SDK.1.0.0.Preview2-003133-x64.exe. After having closed and reopened our command prompt, running dotnet gives the following output.
The term 'dotnet' is not recognized as the name of a cmdlet, function, script file, or operable program.
We have tried the following:
- Uninstall all versions of Visual Studio.
- Uninstall all versions of .NET Core.
- Repair C++ Redistributable 2015 x86 & x64
- Restart the computer.
- Then reinstall the .NET Core SDK.
This is the contents of C:/Program Files/dotnet

Microsoft .NET Core 1.0.1 - SDK 1.0.0 Preview 2-003133 (x64).swidtag
Our PATH includes C:\Program Files\dotnet\
回答1:
Also ensure that "C:\Program Files\dotnet" is part of the "path" system environment variable.
After uninstalling previous SDK versions, it had disappeared from mine.

After again coming across this problem, we found the answer here.
Open Programs and Features, choose Microsoft Visual C++ Redistributable (x86), click Uninstall and then choose Repair. After repairing it (and the x64 version if you have it), reinstall or repair the installation of the .NET Core SDK 1.0.1.

This error also occurs if .Net core is not installed on your machine. To verify it, please run the comman dotnet --help from Windows powershell or VS Code terminal. If .Net core is installed then you will see the output else same error. If you see the same error then:
- Please install it from here https://dotnet.microsoft.com/download.
- Then close whatever CLI or Code editor you are using like VS Code.
- Now open them again, run your command (dotnet new webApp -o aspnetcoreapp) and you will get rid of your problem.

In my case the issue had to do with the x64 vs. x86 discrepancy.
My path had x86 in it. I manually changed it to "Program Files" rather than "Program Files (x86) and it started working again.
