First, What do you mean by "I have done", does it mean you having nothing else to learn in .Net?
Now, to your question,
Go back 10 years (may be to the year 2001)and recall how the .Net and C# was doing. Visualize the changes since that.
however, in next 15 years or so, the changes is going to be further sharp. No one can predict this.
Best ways are to,
1. Not only learn a language or technology, Learn the technique "How to learn and adopt"
2. Learn to travel with the time

We are now in the planning stage of the next web based project using C#, MVC 5 and Entity framework 6. We are discussing about framing the project using the Repository pattern. We already have the full database ready. So, it is going to be Database first.
Now, my question : Is it feasible / worth using Repository pattern with database first approach? I got this doubt because, many sources and examples found in internet are Code first approach. If it is possible can you please provide me any advice or online/article sources to refer. Thanks.
I welcome any ideas or suggestions on Repository pattern.

Of course you can. Mind you, I would suggest that you don't just concentrate on this one pattern. I find that it goes hand in hand with the Unit Of Work pattern to help simplify things.

As Pete O'Hanlon said, you can. We use the Repository pattern + Unit of Work on the project I'm on right now. While we do use Code First, there is no reason it can't apply to Database First as well. Someone can correct me if I'm wrong, but I don't think the purpose of the Repository pattern was designed specifically for Code First. One advantage of using Repo is testing, another is dependency injection. It's simple to test using a Repository, from what I can tell here.

How do I compare two tables and get the difference?
Dim dtBenefitsCurrent As New DataTable
dtBenefitsCurrent = objDB.GetPlanBenefits(groupID, planID, SequenceNumber)
Dim dtBenefitsPreviousYear As New DataTable
dtBenefitsPreviousYear = objDB.GetPlanBenefits(PreviousgroupID, PreviousplanID, PreviousSequenceNumber)
Dim dyDifference ????
|
|
|
|
|
Do you want to compare their structure, or their data?
The most obvious way is looping through the data, and looking whether the second table has the same. Exit as soon as they are not, or loop until the end and return a list of differences.
AFAIK, there's no built-in functionality to compare datatables and get a diff.

Please help me...
objCreateMasterBenefit.CreateMasterBenefitDocument return SpreadsheetDocument how can I output so users can choose to save/open doc in web apps...
Dim MemoryStream As New MemoryStream
Try
Response.ClearHeaders()
Response.ClearContent()
Response.Clear()
Response.Buffer = True
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet.main+xml" '"application/vnd.openxmlformats-officedocument.spreadsheetml.worksheet+xml" '"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" '"application/vnd.ms-excel"
Response.AddHeader("content-disposition", "attachment; filename=" & lblEditedPlan.Text)
Response.Charset = ""
Me.EnableViewState = False
objCreateMasterBenefit.CreateMasterBenefitDocument("Master_Benefit_"".xlsx", MemoryStream, groupID, planID, SequenceNumber)
MemoryStream.WriteTo(Response.OutputStream)
Response.Flush()
Catch ex As Exception
Throw
Finally
MemoryStream.Close()
MemoryStream.Dispose()
End Try
Response.End()
Response.End()

Are you asking how to put something in a MemoryStream? Or why your code doesn't work?
If the latter then you are going to need to explain more what it does do (versus what you want it to do.)
Also, but just guessing, your content type values seem much more complex than I would expect.
|
|
|
|

Try
MemoryStream.Position = 0
MemoryStream.WriteTo(Response.OutputStream)
Next to that, you'd want to rename that to have some other name than the class! Call it "MyCoolMemoryStream", but don't copy the name of the class and use it as a variable - makes stuff hard to read.
Also, you'd like to give that method that creates the file an enum, denoting "Excel XML" - the method itself should find the proper file-extension that should be used therefore.

I just notices most of the blogs I used to follow are no more updated by they creator.
What are the good .NET / C# / Application Lifecycle blogs with RSS feed of this moment. I prefer to follow people than organizations. I like blogger that write one article, news or tutorial by weak or month.
Thank you,

You have to go and look for them. There are many here on CodeProject, but if you want others then they could be anywhere.

I found the technical blogs on this website but I don't know how to subscribe to a RSS feed of these blogs

Whilst prototyping a console app the other day, it stuck me that the dynamically linked library seemed somewhat redundant in .NET and that was nothing I could do with one that could not be achieved by creating an executable. I can add a reference and reuse publically declared types whilst with both. But an executable has some obvious benefits, yet I've always created DLLs because I've been told 'it's best practice' or just followed other's examples.
Can anyone think of a technical reason why you'd choose to build a library over an executable? Is a DLL an artefact simply for some legacy backwards compatibility that I'm unaware of?
Thoughts?

Like what? 
The only "benefit" an executable has over a library is that it can be executed directly. For the vast majority of class libraries, executing them doesn't make any sense.
For example, what would you expect to happen if you executed mscorlib? System.Data? Etc.

What if you required that they tested and verified themselves?
|
|
|
|
|
What do you mean by "tested and verified themselves"??
|
|
|
|
|
Say, main() by default was required to call a bunch of test suites that executed unit tests. I once worked somewhere where they did this btw.
|
|
|
|
|
Soooo, you're going to ship your unit tests with the code to the customer? That sounds stupid. That's like shipping the Paint Shop from the assembly plant with the car that it built.
|
|
|
|
|
Sounds more like including the diagnostic reader device with the car rather than requiring a visit to the shop when the check engine light comes on.
|
|
|
|
|
When was the last time you executed unit tests on customer site?
I've written seperate tools to diagnose database problems, but never to verify "the code". If the .EXE gets corrupted, chances are good it won't even run, and if it is corrupted, chances are good you've got hardware problems.
