c# - PowerShell Commands Adding EF Migration by Code -

wondering if can me solve this.

i able use package manager console enable-migrations, add-migrations etc etc. want able using c# code via powershell object

what have far is:

var ps = powershell.create(); ps.addcommand("set-executionpolicy"); ps.addargument("unrestricted"); ps.addcommand("import-module"); ps.addparameter("name"); ps.addargument(@"'.\packages\entityframework.6.1.3\tools\entityframework.psm1'"; ps.addcommand("add-migration"); ps.addparameter("name"); ps.addargument("migration21sept"); ps.addparameter("projectname"); ps.addargument("context1"); ps.invoke(); 

but when execute code error stating: "the term 'add-migration' not recognized name of cmdlet, function, script file, or operable program"

browse entity directory, shift + right click select "open powershell window here"

dotnet ef migrations add "migrationname"
