If not set, the command will search for a main.bicep file in the current PWD. If the file is not found, an error will be thrown. .PARAMETER SpecificParameterFile Specifies the name of the parameter file to use. If not set, the command will search for a parameter file in the following order: [stage].json, parameters.[stage].json, parameters/[stage].json. If none of these files are found, an error will be thrown. .PARAMETER ResourceGroupName Needs to contain the name of the target resource group if the BICEP target scope is set to resourceGroup. .PARAMETER ResourceGroupLocation Needs to contain the name of the Azure region where to deploy to if the BICEP target scope is set to resourceGroup. .PARAMETER ServicePrincipalType Specifies the type of service principal to use.

The script must take at least Stage, ParameterFile and WhatIf without any other mandatory as parameters in. .PARAMETER PostScriptFile Optional path to a script which needs to be executed after the actual deployment happens.
