I suggest you read the following article and work through it since it gives you a good understanding of how the file system watcher is used:

Take your time to formulate a question; as it is now, I'd simply point to the documentation and answer "use it correctly".
What is it, specifically, that you need help with, or want advise on?

Hi, I recently found that knowing a .NET programming language itself isn't enough to become a pro .NET developer. So my question is where can I find best ebooks about knowing .NET framework structure, deeply and completely?

.NET developer is very a broad term; it does not imply that you lack in-depth knowledge of the for loops, but that there are "area's" that you could still explore.
.NET can be used to develop web-apps, cross-platform desktop-apps and mobile apps. Did you try all three of those? Desktop can be divided into various GUI-concepts, like WinForms, WPF and Gtk#. Besides that, .NET offers some various additional technologies that are interesting to learn, like serialization, the MEF-framework, WCF and WF.

Amazon, Manning, Google. Brownfield development[^] is a good place to start; even for greenfields 
If you seriously want to dive deeper in the way .NET works, I suggest you Google for some CodeProject-article's on IL.
If you can specify what area of development you're targetting, you'll get a bit more specific answer.

You have targetted the Client Profile in your project (take a look in the project properties). This doesn't include the web assemblies. You need to change your profile to the full .NET 4 profile to get access to System.Web.

See here[^] and here[^].
One of these days I'm going to think of a really clever signature.

For love nor money I cannot get the syntax right.
I want to return 3 x 2D arrays from a function but can't wrap my head around it - I suspect I have just failed to grasp some fundamental aspect of jagged arrays!
Public Function SVD() As Double(,)(,)(,)
Dim arS(,) As Double
Dim arU(,) As Double
Dim arV(,) As Double
...Fill the Arrays...
Dim arSVD(,)(,)(,) As Double
arSVD(0) = arS
arSVD(1) = arU
arSVD(2) = arV
Return arSVD
End Function
If I have it that way the error is on arSVD(n) and says 'Number of indices is less than the number of dimensions...'
If I change the return type and arSVD to Double()()() then the error is on the last arS and says 'Value of type 2D array cannot be converted to 1D array...'
If I change it to arSVD(0,0) for example the error is on the last arS and says 'Value of type 2D array cannot be converted to type 2D array of 2D array...'
Bash. Head. Brick. Wall.
Any help very gratefully received.

Wow, I'd forgotten just how horrible VB's array syntax[^] is! 
Try this:
Public Function SVD() As Double()(,)
Dim arS(,) As Double
Dim arU(,) As Double
Dim arV(,) As Double
Dim arSVD(2)(,) As Double
arSVD(0) = arS
arSVD(1) = arU
arSVD(2) = arV
Return arSVD
End Function

Thanks, Richard.
Quite why I couldn't work out ()(,) I don't know, so simple when you know!
I blame VB array syntax too
That link should be VB arrays[^]

Probably also worth noting, for posterity, that I solved this problem using a structure, 3 private members as double(,) and a constructor that takes the same as paramaters and off you go - quite a few advantages of doing it this way and I could also add a second constructor using just one parameter, the syntax Richard gave : ()(,) as double.

Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machinekey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.
iam getting the above error in my site please help me.

This exception generally appears because Controls using DataKeyNames require Viewstate to be encrypted. And the viewstate hidden field might not have been rendered to the browser with long-running pages, and if you make a postback before it does, the page doesn't know that Viewstate is encrypted and causes the aforementioned Exception.
The problem happens specifically when you postback before the EventValidation field has been rendered.
Workarounds:
1. Set enableEventValidation to false and viewStateEncryptionMode to Never OR
2. Mark the form as disabled and then enable it in script once the load is complete OR
3. Override the Render Event of the page to place the hidden fields for Encrypted Viewstate and Event validation on the top of the form
Have a look at this blog for full details: MSDN Blog: Validation of viewstate MAC failed error[^]

As you are running x64 windows and Microsoft.Jet.OLEDB.4.0 provider is not 64-bit compatible.
It seems to be version problem with the provider.
You can try this option and see if it gets ressolved:
1. From the solution explorer right-click your project then click Properties
2. Click the Build tab
3. Change Platform target from: Any CPU to x86
4. Re-build your solution
This may work.
Thanks
Soumen Mazumder
Happy Coding
