Would it be a good choice for use within a WCF service written in C#? I'm currently using FirebirdSql, but that's giving me way too many problems. Documentation and support is also horrible.
edit: Sorry, I should have been more specific when asking the question. What I meant was whether or not SQLite is a good choice for an embedded database within C#. MS SQL is out of the question for this one.
SQLite is a great platform for any language, however there are small concerns I've had with it under .NET.
It is natively compiled. This breaks .NET's AnyCPU Implementations of .NET (i.e. you have to explicitly distribute a 32bit & 64bit version of your app, and have some hand-written rules in your .csproj (MSBUILD) file to select the different dependencies based on what you select.
It has some sticky threading issues. You're going to run into trouble if you're trying to use the same DB from multiple places (multiple instances of your app) etc. It's doable, but it basically uses a simplistic form of database/table locking to achieve this, which could be a major concern based on your program.
All In all i really like SQLite, but if I could find one that didn't require a redistributable (*cough*SQL Express*cough*), I would use another embedded DBMS for .NET Apps. To date I havent found one aside from Raven DB but that's a document DB.
Edit: Note, Raven DB Is also only free for open-source applications. It's not suitable for proprietary applications unless you're willing to shell out for a licence, so when looking into it please be sure to factor it into your budget.
SQL Express always works well

Is there any way to configure mySql as a database server with concurrency access?
I want to develop a windows application with a open source database where multiple access at the same time. as per the research I did on the internet, Mysql is the best but just want to make sure that Mysql capabilities in the above scenario.
any help appreciated.
I believe that you're misunderstanding something, but I'm not sure what, so I'll just explain stuff a bit :-)
MySQL's single and sole purpose is what you describe. It's to store data and allow it to be accessed concurrently without too many problems.
Your question is a bit like asking "Is there any way to use a hammer to hit a nail? I have a large amount of nails here, and I need to fix some pieces of wood to each other, and I need something to slam them in. Will a hammer do?"
That said, besides MySQL, there's also nice alternatives like PostgreSQL. PostgreSQL is a bit more full-featured, and has recently been taking over MySQL in popularity. Also, "MariaDB" is, effectively, the new name of the latest MySQL version, so you might want to google for that.
Finally, since you want to develop a Windows application, maybe neither of these databases are a good choice - if every user needs to install a database server in order to use your application, installation will be difficult and error-prone (believe me - I have once, maintained the installers for a Windows application that depends on a MySQL server on the user's computer, and it's hell). You could also look into SQLite, a database (which also supports concurrent access) that you can bundle immediately with the program you're making. It's really just a library that you link into your program, so it's not a server at all. But it's a full-featured SQL database.

I need to develop an evaluation tool using C# that will run on the system for hours and then will show the overal performance of the system.
The system is supposed to run a service and we want to evaluate how this service is affecting the performance of the system. Will be great if I could use the performance counters that are available in "Windows Performance Monitor"... I'm not sure if there is any API available for developers to use them.
I was just looking for suggestions...
Thanks
If it were me, I'd use perfmon. The advantages are:
Well known data archiving model that offers multiple formats.
Existing tooling to slice and dice the data, including visualization.
Integrates with other systems if the client cares (ie lets them suck the data in to other performance tooling).
Someone else's code. :)
You can wrap perfmon and invoke it programatically if you want. Worst case just invoke it via the command line and start/stop collection that way.
Of course you can also expose your own performance counters for app specific stuff too. There are loads of APIs for this for just about every programming environment I can think of on Windows, including of course C#.
I would strongly suggest you use an existing option like automating the collection of WPM statistics.
otherwise C# may not be the best choice since hardware is almost completely abstracted away from the code by the runtime. additionally the application may require sufficient resources and time to contaminate your results. usually the performace cost between C++ and C# is neglible, but in this case could be a problem.
Good luck.

Basically I wanted to know which technology and languages should I use if I wanted to build a windows application. My requirements are:
my application must be able to store data entries.
a simple GUI.
I should be able to distribute my application as an .exe file
I did some research and found out that I should use C# and wrap a mysql db in my application. Is this the correct way or is there any other and better method than this?
I am a newbie developer and have worked only with java, so please bare if its a silly question.
Aside from learning C#, as you know Java already, you can also develop a Java app and use a wrapper tool like launch4j and jsmooth to distribute it on Windows and have it configured to automatically install JRE if there's none.
There will always be arguments over the 'correct way' and whether one method is 'better' than another. Threre are also a couple of 'it depends' aspects to your question.
Having said that, yes, C# is a well recognised technology for developing windows applications, and mysql will provide a means to add database abilities to the application, so you are well on the way. (Trust your research :).
Do you intend to develop a multi user application that takes data from different sources? For this, you will need to think about deploying the database separately to the application and network/internet access etc etc. Also, if this is the case, you may want to think about a more robust database solution like sql server. There are a number of versions of this database (see here for some info: http://www.sqlmag.com/article/sql-server-2012/sql-server-2012-editions-142261).
If your application is going to be standalone, then deploying an instance of mysql within the application will work, but you may want to consider something with a smaller footprint (sql server compact, or sql lite maybe).
hth
for a newbie for such a nice and clear question. Yes you can use C# with windows form to build up your app. But You cannot pack you db inside an exe. It must be an external resource. Better go for C# with SQL Server as Sql Server is its native and has far better support than any database available. Also you have express edition of the same to use upto 10GB and most important its free....
As per my concern you can go with c# application. But nobody can tell whether it is simple to you or not. It depends on how you understand the concepts and syntax of the language. I recommend you to go with C# and MS SQL Sever Express Edition.

We have a software which we use in-house for our day to day work.
It is like a customize CRM (sort of) and Bug Tracking software. We had a small team of 3 developers who had developed this software. Now this team is also working on other assignments.
Recently we are receiving a lot of request for adding functionality from users (who are our employees and all of them are developers working of different projects) in our firm. The original team that created this software does not have enough time to work on enhancing this software. So instead of spending a lot of time in updating as per request and the updating the executable of software for each user, we want to implement a programming/scripting solution that is if possible free and open source.
I was thinking of adding support for a language which is similar to C# to our application. This way the developers will add the features that they require on their own in their spare time if they really need a feature!
Can anyone point me to some such implementation already existing?
I don't know if I am taking the right decision or not regarding C# I would like to get opinion of experts on this also.
TIA
The framework already comes with a C# compiler you can use at execution time via CSharpCodeProvider.
You might want to look at the source code to Snippy, a small tool I wrote for C# in Depth - that compiles code on the fly, and can act as a reasonably simple introduction to CSharpCodeProvider.
I think I'd look at a scripting solution here; probably IronPython is the easiest to bundle and host, but others are available (including Javascript.NET, IronRuby, IronScheme, Boo, F#, etc)

I mainly develop Java EE webapps so I don't have any experiences with desktop application at all. Now a friend of mine needed a little tool for daily business which I've build with Seam and a MySQL db in the background. In case of my experience this was done really fast.
Now I want to go further and produce a real small desktop app for him. I've looked at various options and developing a gtk# application with Mono seems my way to go for this little project. The application should be small and fast so I was thinking if a whole MySQL server is needed for my solution here.
What options I could evaluate instead of a database server which has to run as a service on the workingmachine? Storing data as XML?
To clarify the application has now 6 entites (Products, ProductTypes, Colors, Sizes, Orders, Production). On daily basis orders and production are added to a ProductType, very simple stuff.
XML would work for small sets up data, but if you are going to have larger sets I would recommend something like sqlite.
http://www.sqlite.org/
I have looked at various options and I tend to like SQLite
for client applications on .NET. It is a file based solution that does not require a database server to be installed on the machine, much like using an Access database but better.
Try SQLite
Can be other DB will interest, for example, Db4o or SQL CE 4.
