I have created timer job and under execute method.i have added below statement to run sharepoint command.
runspace.RunspaceConfiguration.AddPSSnapIn("Microsoft.SharePoint.PowerShell", out snapInError);
but i am receiving error wherever this code is getting executed.
Cannot load Windows PowerShell snap-in Microsoft.SharePoint.PowerShell because of the following error: Could not load file or assembly 'file:///C:\Windows\Microsoft.Net\assembly\GAC_MSIL\Microsoft.SharePoint.PowerShell\v4.0_15.0.0.0__71E9BCE111E9429C\Microsoft.SharePoint.PowerShell.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
Please help my requirement is to create timer job which will run my custom powerShell script
