Terraform (and AzureRM Provider) Version

Terraform version: 0.13.5
Provider AzureRM: v0.35+ (including latest v0.37)

Affected Resource(s)

virtual_desktop_workspace_application_group_association

Terraform Configuration Files

resource "azurerm_virtual_desktop_workspace_application_group_association" "workspaceremoteapp" {
  workspace_id         = azurerm_virtual_desktop_workspace.workspace.id
  application_group_id = azurerm_virtual_desktop_application_group.appgroup.id
}

Expected Behaviour

No modification on the existing azurerm_virtual_desktop_workspace_application_group_association

Actual Behaviour

terraform apply cause virtual machine replacement but no modification in tf file. This problem appear in 0.35 and is still present in 0.37. When reverting to 0.34 no modification found when terraform plan/apply
Here is the plan output with 0.35+:

Terraform will perform the following actions:

  # module.azurerm_virtual_desktop_test.azurerm_virtual_desktop_application_group.appgroup will be updated in-place
  ~ resource "azurerm_virtual_desktop_application_group" "appgroup" {
      ~ host_pool_id        = "/subscriptions/XXXXXXXXX-XXXX-XXXX-XXXX/resourceGroups/TEST-rg/providers/Microsoft.DesktopVirtualization/hostpools/SRVTEST-hp" -> "/subscriptions/XXXXXXXXX-XXXX-XXXX-XXXX/resourcegroups/TEST-rg/providers/Microsoft.DesktopVirtualization/hostpools/SRVTEST-hp"
        id                  = "/subscriptions/XXXXXXXXX-XXXX-XXXX-XXXX/resourcegroups/TEST-rg/providers/Microsoft.DesktopVirtualization/applicationgroups/SRVTEST-appgroup"
        location            = "eastus"
        name                = "SRVTEST-appgroup"
        resource_group_name = "TEST-rg"
        tags                = {}
        type                = "Desktop"
    }

  # module.azurerm_virtual_desktop_test.azurerm_virtual_desktop_workspace_application_group_association.workspaceremoteapp must be replaced
-/+ resource "azurerm_virtual_desktop_workspace_application_group_association" "workspaceremoteapp" {
      ~ application_group_id = "/subscriptions/XXXXXXXXX-XXXX-XXXX-XXXX/resourceGroups/TEST-rg/providers/Microsoft.DesktopVirtualization/applicationgroups/SRVTEST-appgroup" -> "/subscriptions/XXXXXXXXX-XXXX-XXXX-XXXX/resourcegroups/TEST-rg/providers/Microsoft.DesktopVirtualization/applicationgroups/SRVTEST-appgroup" # forces replacement
      ~ id                   = "/subscriptions/XXXXXXXXX-XXXX-XXXX-XXXX/resourcegroups/TEST-rg/providers/Microsoft.DesktopVirtualization/workspaces/SRVTEST-ws|/subscriptions/XXXXXXXXX-XXXX-XXXX-XXXX/resourcegroups/TEST-rg/providers/Microsoft.DesktopVirtualization/applicationgroups/SRVTEST-appgroup" -> (known after apply)
      ~ workspace_id         = "/subscriptions/XXXXXXXXX-XXXX-XXXX-XXXX/resourceGroups/TEST-rg/providers/Microsoft.DesktopVirtualization/workspaces/SRVTEST-ws" -> "/subscriptions/XXXXXXXXX-XXXX-XXXX-XXXX/resourcegroups/TEST-rg/providers/Microsoft.DesktopVirtualization/workspaces/SRVTEST-ws" # forces replacement
    }

Steps to Reproduce

1. Implement VDI hostpool and virtual machine. Use azurerm_virtual_desktop_workspace_application_group_association and update module to 035+
2. terraform plan
