How to store a List<> object in WP7 Local Database?
List<CheckBox> lcb = myListBox.Items.OfType<CheckBox>()
.Where(c => c.IsChecked == true).ToList();
I used OfType instead of Cast because OfType will work even if there a single checkbox item or all items are checkboxes.
In case to Cast it will give error if even a single item is not checkbox.

How to check is a List entry is not e.g. 0.0?
I just know how to check if it is 0.0 like this:
MyList.Where(a => a.Equals(0.0))
but how to check it if it's not?
To check if a list contains a number: if (myList.Contains(0.0)) ...
To check if a list does NOT contain a number: if (!myList.Contains(0.0)) ...

How can I debug linq query? when query is too long
Debuggen is very limited with linq. See the link #JW shown in the comment.
But in you case you could split it up. It makes it's easier to see thats going on.
var tmpLst = panelInfo.AsEnumerable()
.Where(panelModel =>
panelModel.Field<string>(modelNumberColumnName) == solution.ModelNumber)
.Select(panelModel => panelModel.Field<int>(voltageListSupportedColumnName))
.Distinct()
.ToList();
foreach(var item in tmpLst)
{
voltagesSupported.AddRange(
ModelInfoController.VoltageInfos[(uint)item]
.Select(voltage => (int)voltage)
.ToList()
}

I need to check that a List contains or not values that are greater that a specific value. How could I doing so?
Using LINQ:
bool contains = yourList.Any(z => z.YouProperty > yourValue);
You can use Enumerable.Any<TSource> method. It returns boolean.
Determines whether a sequence contains any elements.
Return Value
Type: System.Boolean
true if the source sequence contains any elements; otherwise, false.
List.Any(a => a.Property > Value);

How can I turn these two bits of code into one?
comCtrList = (from i in genOutList
join f in genAccList
on i.Contract equals f.Contract
select i.Contract).ToList();
genOutList.RemoveAll(acc => comCtrList.Contains(acc.Contract));
Do you want something like this?
genOutList= (
from i in genOutList
where !genAccList.Any(x=>x.Contract==i.Contract)
select i
).ToList();
Or
genOutList.RemoveAll(x=>genAccList.Any(i=>i.Contract==x.Contract));

string last = url.Substring(url.LastIndexOf('/') + 1);
var provisionedSiteRequestRep = provisioningRequestRepository.SelectFirst(new WhereSpecification<ProvisioningRequest>(result => result.SiteUrl.Contains(last.ToString())));
Some time i am getting the null values of last.tosting() so i am getting exception for this code how to resolve this?
You are facing problem on this line
(result => result.SiteUrl.Contains(last.ToString());
Can you please check that SiteUrl is type of string otherwise it not going to work for you.
because last is type of string and Contains is method supported by string type ...
or
otherwise last need to be enumebrable collection and siteurl also enumerable collection than and only than Contains is supported
