I would need to create some webpages that are using jscript and different jscript libraries heavily and I will need to write a littlebit of code and debug it through to see if that works. I would like to know if there is an IDE exists on Windows jsut to do this or there is a combination of tools that can be used for this purpose?
I'd suggest Visual Studio Web Express, which you can easily configure to be a JScript debugger: http://www.berniecode.com/blog/2007/03/08/how-to-debug-javascript-with-visual-web-developer-express/
Visual Studio
Since JScript Microsoft dialect of ECMAScript.
In my opinion hands down the best JavaScript debugger available for windows is Visual Studio, unfortunately its far from free however the link that naivists posted allows you to use Visual Studio Express - Web Developer Edition (which is free) to do the same thing:
How to debug JavaScript with Visual Web Developer Express
You could also look into using tools like Firebug (Firefox only) - these sorts of tools are very good at inspecting and tweaking the layout of the page, however I've always found the JavaScript debugger to be a little lacking.

We have few classic ASP web applications which are to be converted to ASP.NET Core. Few questions:
1) Are there any tools which can help in migration
2) I have Windows server 2016 - what version of Visual studio , edition and framework is required to be installed on the server ?
3) Are there any other software / NuGet packages which are required as pre-requisite ?
4) What should be the approach taken for such migrations ?
Thanks
ASP.NET and ASP.NET Core, despite both having "ASP.NET" in their names are fundamentally different things down to their core, no pun intended. As such, no, there is no "tool" to migrate for you, because it basically requires a rewrite. You should not look at moving to ASP.NET Core as a "migration". You are creating a brand new application. The way you structured your previous app, how you chose to do things, the very architecture itself, will all need to be re-evaluated, just as if you were starting from scratch, because you essentially are.
I'm actually in the middle of such a "migration" myself, but I've taken the opportunity to move to a microservices architecture. As such, I'm essentially just breaking off pieces of the old application and replacing them with microservices. This makes it relatively easy and straight-forward to start using ASP.NET Core while at the same time keeping your existing ASP.NET application working, limiting the scope of the changes required. Eventually, once all the core functionality is spun off, all you'll essentially have left is the UI, which is a rather simple replacement overall.
As far as tooling, you must have Visual Studio 2017, edition does not matter. 2015 can only work with up to .NET Core 1.1, and not well even then. 2019 will be a better option once it's generally available. Basically, just use whatever the latest GA version is always. There's some benefit with the Enterprise edition as you get things like Live Unit Testing with that, but you can develop full ASP.NET Core apps on even the free Community edition, just without all the Visual Studio extra bells and whistles you get for paying for higher versions.
NuGet packages are specific to your app, so you'll decide on those as you build. As far as other software goes, if you want to take the same microservices architecture approach, you'll want to have Docker for Windows installed. Generally, you'll of course also need the .NET Core SDK you plan to target installed, as well.

I have a system that runs on MSAcess and the client want to upgrade this to SQL Server. What version do I need to have on my development machine? If the client has SQL 2010 Enterprise will it be compatible with SQL Express on my development machine? What are the pitfalls of having these two different versions? Will I be able to backup my Express version and restore it to their 2010 Enterprise version?
All help will be greatly appreciated.
Regards
Mac
The best option is a Developer Edition. It has feature parity with Enterpise Edition but, as is only licensed for Developer work and not for production, it costs around $50.
Express Edition is also a feasible choice, as is free, but you'll miss some of the more advanced features and if your client(s) ask for these features you won't be able to test. Examples of useful features you'll miss are SQL Server Agent, Reporting Services, SSIS or Database Mail.
Will I be able to backup my Express version and restore it to their SQL Server 2012 Enterprise Edition?
Yes, as long as you make sure your version is at most the client deployed version and not any newer. You also need to ensure all your application is contained in the database (no dependency on logins, agent jobs etc), which is tricky. But you should absolutely do not do this. Your deliverable cannot be a database binary (mdf/ldf or backup), but it must be a script to deploy the database. If you fail to do this, your will have a big problem after one week when your client will ask for an update. Threat the database as code. See Version Control and your Database. Read about Rails Migrations for a good approach to this problem.
If you develop your application with an Express edition you should not have any problems if the user has a Enterprise edition running.
You can see the feature comparison sheet following this link: Features Supported by the Editions of SQL Server 2008 R2.
P.S. There is no SQL Server 2010. I think you mean SQL Server 2008 R2, thus the link provided links to that content.
If you upgrade your Access Database to a SQL Server Database you might have problems if you use Multiple Values in Access. For further possible incompatibilities follow this link.

Do I have to get the developer license for develop a basic sample application on windows 8? I tired open a windows store project with visual studio 2012 and it says get a developer licence. I can not see the design mode. I can not see anything how my application looks like? I can not run it. How can I run with debug on visual studio without a developer licence? I just want to develop a basic application and run it on my windows 8 system? Is this possible?
For a developer license you only need a live ID, so it's basically a 30 seconds act to gain one. After that you freely build&run projects on your computer.

I have been trying to install the Windows Phone 8 SDK on a Windows 8 (x86) machine. But to no avail even though I read somewhere on the site that it will install but I will not be able to run the emulator.
Is Microsoft serious that Win Phone 8 apps can only be developed on 64-bit machines?
They make it quite clear the x64 is required on the download page:
Windows 8 64-bit (x64) client versions
I can't say with any authority, but I suspect it is because the emulator uses Hyper-V, which also requires x64:
Hyper-V requires a 64-bit system that has Second Level Address Translation (SLAT).

I have downloaded the sample database for SQL Server 2012 Express but I am having the following error message whenever I try to attach it:
The database 'AdventureWorks2012' cannot be opened because it is version 706. This server supports version 655 and earlier. A downgrade path is not supported.
Sounds like the server you are trying to attach the database to is not SQL Server 2012. This may be the version of Management Studio / Management Studio Express you're using, but I suspect SELECT ##VERSION; will tell you something different. It may just be a connection string mixup if you have multiple instances of SQL Server installed, otherwise you should download and install SQL Server 2012 Express from here.
