SharpRepository in a concurrent system

First off thanks for the compliment.
You need to tell SharpRepository what IoC you are using if you want it to create the DbContext with the Windsor rules you setup. This might be the issue but I’m not sure. Try adding this and seeing if it helps:
RepositoryDependencyResolver.SetDependencyResolver(new WindsorDependencyResolver(container));
It also sounds like it isn’t creating a new IRepository for you each time. I don’t use Windsor, so it’s possible that the logic in the container.RegisterSharpRepository isn’t setup properly.
Here is what it is doing and it should be setup for IRepository to be transient and not a singleton but maybe I implemented it wrong and my understanding of the Windsor container is incorrect.
container.Register(Component.For(typeof(IRepository<>)).UsingFactoryMethod((c, t) =>
{
var genericArgs = t.GenericArguments;
return RepositoryFactory.GetInstance(genericArgs[0], repositoryName);
}));
container.Register(Component.For(typeof(IRepository<,>)).UsingFactoryMethod((c, t) =>
{
var genericArgs = t.GenericArguments;
return RepositoryFactory.GetInstance(genericArgs[0], genericArgs[1], repositoryName);
}));

If that is the default behavior for Windsor then that would explain what is happening. Let me know if that works out and if so it would be great if you could send a pull request for that. I think it is a really nice enhancement.
And that makes me think it would make sense to provide similar overrides for the other IoC extension methods as well in the future.
Thanks.
Jeff

"The operation cannot be completed because the DbContext has been disposed"
error after the site runs for a short period of time. It seems like the repositories are not being created upon every request. I'm using StructureMap 3.0.3.116. Could this be because the controllers are not being created upon every request?
Our StructureMap configuration looks like so:
public static class IoC {
public static IContainer Initialize()
{
ObjectFactory.Initialize(x =>
{
x.Scan(scan =>
{
scan.TheCallingAssembly();
scan.WithDefaultConventions();
});
x.For<IEventLogRepository>().Use(c => new
EventLogRepository("efLoggingRepository"));
});
return ObjectFactory.Container;
}
}

I usually setup SharpRepository to share the DbContext using StructureMap. Checkout the section title "EntityFramework and Sharing The DbContext" here for some more info: http://fairwaytech.com/2013/02/sharprepository-configuration/
Not sure if that is the issue or not, but you could try it.
You need to use the SharpRepository.Ioc.StructureMap NuGet package and call this code:
RepositoryDependencyResolver.SetDependencyResolver(new StructureMapDependencyResolver(ObjectFactory.Container));
As well as configured StructureMap with how you want it to handle creating a DbContext. I usually do something like this:
For<DbContext>()
.HybridHttpOrThreadLocalScoped()
.Use<CustomEfEntities>()
.Ctor<string>("connectionString").Is(entityConnectionString);
