No it is not a good practice to use singleton for Linq2SqL because it is not very expensive to create and dispose the data context yet the data context has to be thought as a unit of work - do what you have to do and dispose it.

Hi,

Is it a good thing to make use a singleton for a linq context?
Or is this otiose?
For example:

mmbMainDataContext mainCtx;

private mmbMainDataContext MainCtx
{
get
{
if (mainCtx == null)
mainCtx = new mmbMainDataContext();

return mainCtx;
}
}

protected void btn_generateSiteMaps_Click(object sender, EventArgs e)
{
using (MainCtx)
{
foreach (var item in MainCtx.tbl_websites)
{
generateSitemap(item.dealerCode, “http://” + item.dnsName, item.languages);
}
}
}

Thanks for the interesting tips!

Very happy to see that this article is still useful to some after 3 years that it has been written and the product is nearly completely castrated by Microsoft to support EF.

Really helpful ideas! I used a combination of the tricks to help improve the performance of 6 LINQ queries I was working on.

One of the biggest improvements came from adding a “.ToList()” to the end of each of my LINQ queries before continuing to process them! I think it give me a performance increase of AT LEAST 50% which was excellent!

Thanks again,

Mark
