I just not sure about the performance of web application using vs.net 2010 & angularjs because has no any post or ideas from someone. Please someone share experiences.
Yes, you can use the two.
Were you thinking Web API and/or MVC and/or SignalR what for your server API calls? (I assume that was implicit - actually haven't used Web API or SignalR on 2010.)
My experience has been that the bottleneck when using Angular is having >2-3k watches, some of which are "deep" causing the whole app to run run slow on the client - MS server technologies are fine. (Of course you can structure your app so that it's really chatty and thus not be performant due to the way you used the underlying technologies but there's nothing wrong with .NET web technologies and AngularJS.)

Currently I'm working in a project which is a SharePoint 2013 sandbox solution, i.e. the custom code is deprecated, leaving with just the front-end JS development which we have implemented in using Angular.
In SharePoint I'm unaware of any server side coding.
So what should be my primary focus with career perspective SharePoint or Angular JS. Please help. Should I start learning SharePoint server-side concepts or invest my time in improvising my Angular concepts.
I think you should be aware of client side code and server side code both. As it depends on your project requirements. As now days client side technology is preferable as it has not much overhead on server also not so many round trips to server. but one should be aware of in both aspects.
Angular JS is a framework you should know JavaScript, jquery and any one JS framework to work accordingly.
There are many way that you can develop server side code and there are lots of tools given by different parties to do the server side code easily. But client side programming is more crucial these days as limited number of tools and knowledge on that area is not very good among the lot of programmers. So my opinion is to learn both but give more focus on client side programming. And make Anguer Js your specialty :)
we are developing an application using HTML/CSS and using the Angular framework. The problem is that we are quite a ways in to development and our client is switching to SAP, I have looked and looked and all I can find is information about SAPUI5 and Fiori. Is there a way we can still use our Angular app as a Fiori application or would we have to switch everything to SAPUI5, it sounds like a lot of work for a custom application that is practically done but I'm not an SAP expert so I was hoping someone could provide some insight around working with Fiori apps.
Thanks -
in general it is probably a good idea to choose either one of the frameworks. Changing to SAP is a bit general, i assume you do mean here SAP HANA cloud platform? If so there is no reason, why you would not be able to use angularjs to continue your application and just use the backend data services via for instance an odata service (which also should be present for a lot of other SAP applications, there is also SAP Gateway to enable this).
So all in all i think it will be possible to go ahead with angularjs, at the end also SAPUI5 is just a frontend framework.
Quick search on sdn.sap.com brings up some interesting articles that might be of help for you like the following.

In addition to what is mentioned in AirBorne04 answer, if you continue to build AngularJS application consuming oData services provided by SAP backend, you will loose all the features provided by Fiori Launchpad (which are many btw). See the link https://help.sap.com/saphelp_uiaddon10/helpdata/en/f9/51b50a07ce41deb08ced62711fe8b5/frameset.htm
Technically, this is not an issue but suppose if your customer wants to implement Fiori Launchpad then it will be an issue. So I suggest that you inform the customer about this in advance so that there are no surprises later on.
I am creating a website with a friend to try and make some money. Basically, we want to let users aggregate data from different social networking site's APIs (FaceBook, Twitter, etc.) and do some cool things with the data.
My non-developer friend is sold on the Google App Engine because it costs nothing at first, and then you pay as your traffic/data increases. I am torn. I like being able to bootstrap the business like that and have no startup costs (other than time) but I am worried about learning a whole new "programming world" as Joel Spolsky would put it.
I am so comfortable with C#, ASP.NET MVC and SQL Server that I think moving to something like Java or Python on top of BigTable would end up taking about 3x longer to develop (if not more).
Can anyone give me some guidance on this? Basically, I am wondering if there is any way I can have the following with the Microsoft stack:
Free hosting up to some limit of traffic
Ability to scale out at a cost similar to what Google offers with GAE (maybe the hosting service would need to have support for a good scalable persistence solution--like Couch DB?)
For #1, I am OK if that means hosting it on my own server for the ALPHA/BETA phases. For #2 I am hoping that there is a good hosting service out there who can put me on shared hosting servers and charge by the traffic. Does that exist? Thanks!
Unfortunately when it comes to a similar platform then you won't find a MS Stack version. Windows Azure comes close but this is more akin to Amazon's EC2.
The python stack in GAE is really easy to use and was able to make the transition quite quickly. Django is a MVC that is really popular and quite simple to use. It also gives you a ORM to write to BigTable which means you don't actually have to care about it.
The Java implementation is very similar and you can use really well know MVC frameworks for creating your app like Spring
I am also a .NET expert, but I have been using Python-AppEngine for hobby/entrepreneurial purposes specifically because it allows me to bootstrap an new web application at no initial cost. That is critical for me, as I have no budget at all for side projects, and so far, with many deployed AppEngine applications, I haven't spent a penny on it.
Learning a new language can seem like a drag at first, but I have come to find my new expertise in Python to be invaluable. Remember that the best and most employable developers are usually generalists with a broad and flexible palette of skills. My resume features C# and .NET as well as Python and Ruby/Ruby on Rails, and I have gotten very positive reaction from potential clients and employers.
Learning Python was dead easy. Getting a handle on WebOb and Django templates took more effort, but nothing extraordinary. Over time, I built up my own framework layer on top of those things that incorporates the best ideas from Rails and ASP.NET MVC that I missed. You can take a look at it on Google Code, and you will see a number of ideas that specifically borrowed from ASP.NET MVC.
I have an asp.net web app which holds its data in an sql server 08 r2 db.
I have a silverlight admin interface on the same web app, and I will have a win forms app which will need to add/retrieve data from the sql db. Is there a way I can use linq in both clients?
I mean something like linq2twitter, where in the silverlight or in winforms app I can use linq to query and update the data.
Currently Im thinking of just using web services, but the data objects are complicated and they're connected to so many other data objects, it would be very convenient to work with them in linq, especially because the asp.net app itself uses a linq data context for its operations. Is there a way to expose this context over http or something?
Thanks
I think you probably want to look at WCF Data Services - which does pretty much exactly what you suggest i.e. it exposes a data context via web services (see also OData) and provides tools to consume and work with same via Linq
I tried WCF Data Services, its freaking amazing but it was a little hard to get up to speed with it, and difficult to diagnose what went wrong where, just for anyone else in my position here is what I did:
I watched this really fun scott hanselman video on OData
Landed on this msdn page after 1 hour of meandering. (Note all the snags like loading related entities, also, there is a list of unsupported linq operations on wcf ds)
Went crazy looking for some examples.
Tried my own stuff with lots of problems--> Got fiddler and then fixed all of them =)
Hope that helps!
Background:
I have basically no experience in Silverlight, i was asked to start reading up on the tech and provide some insight for client which may want to rebuild the UI of their .Net Desktop application in silverlight. So my experience is what i have been able to google (which surprisingly is not easy) and the few tutorials i have done.
I am aware Silverlight could use ASMX Web Service , WCF Services or REST to do communications with the server.
Question:
Are there any other official or non-official mothods of communication anyone knows of?
Thank you in advance,
David

I am somewhat biased having worked on the technology :), but I would urge you to consider WCF.
This method gives you great usability: It literally takes a few minutes to "Add New... Silverlight-enabled WCF Service" to your project and have everything up-and-running. In Silverlight 3, this uses a very performant binary XML protocol under the covers, which can be easily switched to regular text XML for debuging with just a 2-line config change. And it integrates nicely with most authentication models that you would want (see the security section in the doc link above).
Of course, you can roll-your-own communication using HttpWebRequest, WebClient, or even sockets. Using WebClient is probably best if you want to go with REST on the server. Keep in mind that some things that are normally possible in REST (such as using PUT and DELETE HTTP verbs) are not possible in browser plugins such as Flash and Silverlight due to browser restrictions.
Finally, there's .NET RIA Services. It's a bit too heavy-weight for some scenarios and doesn't have some of the WCF features (like binary and duplex), but it's more than just a way to communicate with the server: It gives you a whole perscriptive framework for building SL apps with server-side data, and gives you a lot of nice features like validation, paging, etc. for free.
