Linq to SQL DataContext Windsor IoC memory leak problem
- by Mr. Flibble
I have an ASP.NET MVC app that creates a Linq2SQL datacontext on a per-web-request basis using Castler Windsor IoC.
For some reason that I do not fully understand, every time a new datacontext is created (on every web request) about 8k of memory is taken up and not released - which inevitably causes an OutOfMemory exception.
If I force garbage collection the memory is released OK.
My datacontext class is very simple:
public class DataContextAccessor : IDataContextAccessor
{
private readonly DataContext dataContext;
public DataContextAccessor(string connectionString)
{
dataContext = new DataContext(connectionString);
}
public DataContext DataContext { get { return dataContext; } }
}
The Windsor IoC webconfig to instantiate this looks like so:
<component id="DataContextAccessor"
service="DomainModel.Repositories.IDataContextAccessor, DomainModel"
type="DomainModel.Repositories.DataContextAccessor, DomainModel"
lifestyle="PerWebRequest">
<parameters>
<connectionString>
...
</connectionString>
</parameters>
</component>
Does anyone know what the problem is, and how to fix it?
