Sorry for my poor English.
I’m learning how to make a plugin.
I Try to get content browser and add some menu,here is the code:

auto ContentBrowserModule = FModuleManager::LoadModuleChecked<FContentBrowserModule>(TEXT("ContentBrowser"));
	ContentBrowserModule.GetAllAssetViewContextMenuExtenders().Add(FContentBrowserMenuExtender_SelectedAssets::CreateLambda([=](const TArray<FAssetData>& SelectedAssets)
	{
		TSharedRef<FExtender> Extender(new FExtender);
		if (SelectedAssets.Num() > 0 && SelectedAssets[0].AssetClass.ToString().Contains("Material"))
		{
			
			Extender->AddMenuExtension("MyFirstPlugin", EExtensionHook::After, nullptr, FMenuExtensionDelegate::CreateLambda([=](FMenuBuilder& MenuBuilder)
			{
				MenuBuilder.AddMenuEntry(
					NSLOCTEXT("NSLT_MyFirstPlugin","MyFirstPlugin_Menu","MyFirstPlugin_Menu"),
					NSLOCTEXT("NSLT_MyFirstPlugin", "This_is_my_Tooltip", "This is my Tooltip"),FSlateIcon(),FUIAction());
				MenuBuilder.AddMenuSeparator();
			}));
		}
		return Extender;
	}));

when I try to compile it I got this Error:

I Try to Add “ContentBrowser” to Build.cs but it doesn’t work:

you are trying to use auto container for a FContentBrowserModule class.
u cant do that.
you have to use specific type.
just replace auto with FContentBrowserModule&.

FContentBrowserModule& ContentBrowserModule = FModuleManager::LoadModuleChecked<FContentBrowserModule>("ContentBrowser");

unresolved external error will be gone

that

It works, thank you!
Why it can’t be used with auto?
