Sitecore Microsoft Dependency Injection error "Service has been disposed, cannot create object" - dependency-injection

Question

I am using Sitecore 8.2 Update 4 with Helix framework also using Microsoft Extension Dependency Injection. I have performed few steps for DI:
1. Created DI project in Foundation layer.
2. I have created on pipeline with name Habitat.Foundation.DI.RegisterControllers inside
App_config/Include/zFoundation
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/"><sitecore> <services> <configurator type=" Habitat.Foundation.DI.RegisterControllers, Habitat.Foundation.DI" /></services></sitecore></configuration>
namespace Habitat.Foundation.DI{ public class RegisterControllers : IServicesConfigurator
{
public void Configure(IServiceCollection serviceCollection)
{
serviceCollection.AddMvcControllers("*.Feature.*");
}
}}
namespace Habitat.Foundation.DI.Extensions{
public static class ServiceCollectionExtensions
{
public static void AddMvcControllers(this IServiceCollection serviceCollection, params string[] assemblyFilters)
{
var assemblies = GetAssemblies.GetByFilter(assemblyFilters);
AddMvcControllers(serviceCollection, assemblies);
}
public static void AddMvcControllers(this IServiceCollection serviceCollection, params Assembly[] assemblies)
{
var controllers = GetTypes.GetTypesImplementing<IController>(assemblies)
.Where(controller => controller.Name.EndsWith("Controller", StringComparison.Ordinal));
foreach (var controller in controllers)
serviceCollection.AddTransient(controller);
controllers = GetTypes.GetTypesImplementing<ApiController>(assemblies)
.Where(controller => controller.Name.EndsWith("Controller", StringComparison.Ordinal));
foreach (var controller in controllers)
serviceCollection.AddTransient(controller);
}
}}
public static class GetAssemblies
{
public static Assembly[] GetByFilter(params string[] assemblyFilters)
{
var assemblyNames = new HashSet<string>(assemblyFilters.Where(filter => !filter.Contains('*')));
var wildcardNames = assemblyFilters.Where(filter => filter.Contains('*')).ToArray();
var assemblies = AppDomain.CurrentDomain.GetAssemblies().Where(assembly =>
{
var nameToMatch = assembly.GetName().Name;
if (assemblyNames.Contains(nameToMatch)) return true;
return wildcardNames.Any(wildcard => IsWildcardMatch(nameToMatch, wildcard));
})
.ToArray();
return assemblies;
}
/// <summary>
/// Checks if a string matches a wildcard argument (using regex)
/// </summary>
private static bool IsWildcardMatch(string input, string wildcards)
{
return Regex.IsMatch(input, "^" + Regex.Escape(wildcards).Replace("\\*", ".*").Replace("\\?", ".") + "$",
RegexOptions.IgnoreCase);
}
}public static class GetTypes {
public static Type[] GetTypesImplementing<T>(params Assembly[] assemblies)
{
if (assemblies == null || assemblies.Length == 0)
return new Type[0];
var targetType = typeof(T);
return assemblies
.Where(assembly => !assembly.IsDynamic)
.SelectMany(GetExportedTypes)
.Where(type => !type.IsAbstract && !type.IsGenericTypeDefinition && targetType.IsAssignableFrom(type))
.ToArray();
}
private static IEnumerable<Type> GetExportedTypes(Assembly assembly)
{
try
{
return assembly.GetExportedTypes();
}
catch (NotSupportedException)
{
// A type load exception would typically happen on an Anonymously Hosted DynamicMethods
// Assembly and it would be safe to skip this exception.
return Type.EmptyTypes;
}
catch (ReflectionTypeLoadException ex)
{
// Return the types that could be loaded. Types can contain null values.
return ex.Types.Where(type => type != null);
}
catch (Exception ex)
{
// Throw a more descriptive message containing the name of the assembly.
throw new InvalidOperationException(string.Format(CultureInfo.InvariantCulture,
"Unable to load types from assembly {0}. {1}", assembly.FullName, ex.Message), ex);
}
}
}
As I am using Glass Mapper so I want to use ISitecoreContext, for that I have register ISitecoreContext in Foundation/ORM for that I have performed these actions:
1. Created patch file inside Foundation/ORM
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/"><sitecore><services>
<configurator type="Habitat.Foundation.ORM.DI.RegisterContainer, Habitat.Foundation.ORM" />
</services> </sitecore>
public class RegisterContainer : IServicesConfigurator
{
public void Configure(IServiceCollection serviceCollection)
{
serviceCollection.AddTransient<ISitecoreContext, SitecoreContext>();
}
}
Accesssing in controller like this
private readonly ISitecoreContext _sitecoreContext;
public TestController(ISitecoreContext sitecoreContext)
{
_sitecoreContext = sitecoreContext;
}
I accessing in two classes one way is _sitecoreContext.GetItem(Context.Site.ContentStartPath) and another way is _sitecoreContext.GetRootItem() then it started throwing error “{"Service has been disposed, cannot create object"}” in _sitecoreContext.GetItem(Context.Site.ContentStartPath) but working for
_sitecoreContext.GetRootItem()
When I update AddTransient to AddSingleton then it works for some time for both but for after some time it started giving me null value of _sitecoreContext.
Please help me.
