• You misspelled a built-in dotnet command.
• You intended to execute a .NET Core program, but dotnet-ef does not exist.
• You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH. Running update-database... Could not execute because the specified command or file was not found. Possible reasons for this include:
