How does the ThreadStatic attribute work?
... all the cases (multi-threading, web app multi-threading with async/await, etc) so that a single piece of work (e.g. a single web request, the processing of a single queue message, etc) get its own version of the variable, no matter what?

What is a git topic branch?
...ed in your own repository. You periodically update this branch (using git fetch) to track what is happening elsewhere. When you are ready to catch up with everybody else's changes, you would use git pull to both fetch and merge.
I have also seen another kind of branch which is essentially a complet...
Using a bitmask in C#
... mask I did Mon=Math.Power(2, 0), Tues=Math.Pow(2, 1), Wed=Math.Pow(2, 2), etc. so the bit position is a little more obvious for those of use who aren't used to binary to decimal conversion. Blindy's is good too since it turns into a boolean result by shifting the masked bit.

What is the maximum size of a web browser's cookie's key?
...ou read about is for the entire cookie, including name, value, expiry date etc. If you want to support most browsers, I suggest keeping the name under 4000 bytes, and the overall cookie size under 4093 bytes.

Why no ICloneable?

new T Clone();
}
public abstract class CloneableBase&...

How does a Breadth-First Search work when looking for Shortest Path?
... experience.
When the (undirected for me) graph has
fixed distance (1, 6, etc.) for edges
#1
We can use BFS to find shortest path simply by traversing it
then, if required, multiply with fixed distance (1, 6, etc.)
#2
As noted above
with BFS
the very 1st time an adjacent node is reached, it is sh...
Get the generated SQL statement from a SqlCommand object?
...n improvements :)
This does an OK job on data types and output parameters etc similar to using "execute stored procedure" in SSMS. We mostly used SPs so the "text" command doesn't account for parameters etc
public static String ParameterValueForSQL(this SqlParameter sp)
{
String re...
What is the difference between C# and .NET?
...must be defined and rules governing them e.g. inheritance, object lifetime etc. C++/CLI, C#, VB are all languages conforming to these types (you could in violate this but I wont get into it). .Regardless of what language you use to construct the type, behavior will be same when executed by .NET CLR....
Disabling browser caching for all browsers from ASP.NET
...
This is what we use in ASP.NET:
// Stop Caching in IE
Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);
// Stop Caching in Firefox
Response.Cache.SetNoStore();
It stops caching in Firefox and IE, but we haven't tried other browsers. The following response headers are added...
