From what I have seen on the ormbattle.net, BlToolkit is the fastest ORM for .NET. I would like to test it in one of my projects, but I don't know how to generate entity classes. Should I do this by hand? I have 20+ tables in the database.
Is there any online tutorial or blog, where I can find more information about BlToolkit?
It looks like a library with great potential without community behind it.
you can use our project on bltoolkit code generation:
http://sogen.codeplex.com/
There are the following options:
T4 templates are available for some databases - http://www.bltoolkit.net/Doc.T4Templates.ashx
MyGeneration and template for BLToolkit.
Classes generated for Linq 2 SQL. BLToolkit can use L2S metadata.

The title says it all really. I've found several blogs with different ways (serializing the EF model to XML and then de-serializing again to the IEdmModel was one) but they're all based on old version of the OData package.
Serializing is the only way.
Example.
Relevant work.
I've ranted about this a few months ago. AFAIK nothing changed since then, and I personally don't expect them to change too much. The short story is that as of September 2012, there is no plan to use EdmLib in EF, nor is there to use EF's code in other projects.
How much should we align with OData’s EdmLib?
Not worth adopting code
Cost of implementing SSDL & MSL
Freedom to evolve our API independently
Look at aligning names of types and properties where appropriate
If your DbContext is being built from a database-first approach the given answer will fail giving this error:
Creating a DbModelBuilder or writing the EDMX from a DbContext created using Database First or Model First is not supported. EDMX can only be obtained from a Code First DbContext created without using an existing DbCompiledModel.
After some time messing with this I have found an appropriate solution. Basically you grab the CSDL resource from the assembly containing the DbContext in question and parse it using the Microsoft.Data.Edm.Csdl.CsdlReader.TryParse method. The resulting IEdmModel is valid containing the exact information given by EntityFramework when the model was built.
See here for an example with usage
I am new in entity framework and mvc3.how can i execute Stored procedure in Entity framework with multiple parameters in mvc3.
This depends if you are using code first or not. I do agree with the folks above you could've probably easily researched this but I'll provide an overview here so it's all in one spot to review as there are several options to consider.
With code first in the latest version of EF 6 Beta, you can execute stored procs as part of code-first as described in the docs here
Prior to EFv6 you could use the following to execute a proc in your code and map to an entitycontext.Database.SqlQuery<YourEntityType>
If you aren't using code first, you can map in the designer as explained by Julie Lerman many places, but one easy link is here
I am trying to get any DB queries that happen when using the SqlMembershipProvider to show in MiniProfiler but I can't think of any way to swap out the SqlConnection is uses with a ProfiledDbConnection as it seems to do everything internally. Anyone have any ingenious ideas?
You could download the source (freely avaliable) for the ASP.Net SQL Providers here, read more about it here, Scott Gu published tons of whitepapers in this article about the provider model.
internal to the assembly is a SQLConnectionHelper that you can update to use the ProfiledDBConnection instead. This would give profiling to all the providers using that class, all thats left is to change your .config file to use the new provider instead.
I am planning to use doctrine to write a module of my app which is built with codeigniter.
I have a very basic question :
lets say I have a table called "user", with doctrine generate-models from db, 3 classes are generated BaseUser.php, User.php and UserTable.php. Now as I saw in the examples they use User class straigtaway. Should I be doing this ? I need additional business functionality for the user objects. So should I create a codeigniter model user_model and then use User class inside it (aggregation) or somehow extend user class ( i dont know how this will be done as user_model extends model)
Am little confused on this one and cannot locate any appropriate literature for the same.
Any help would be appreciated.
thanks in advance,
For anyone who is interested - I’ve posted up a project starter on my blog - a dev ready incorporation of the following technologies:
ExtJS : client side JS library,
CodeIgniter : presentation + domain tier,
Doctrine : ORM data layer framework
Some features of this project starter are:
- CodeIgniter Models have been replaced with Doctrine Records
- Doctrine is loaded into CI as a plugin
- RoR type before and after filters….
- Doctrine transactions automatically wrapped around every action at execution time (ATOMIC db updates)
Basic Role based security (I think Redux may be in there as well?)
Simply extract, hook up the database.php config file and viola…. You can start coding your layouts, views and models. Probably a few things to iron out - but enjoy!
Hope it helps

Check out this info on Doctrine_Table class.
To your 3 generated files:
BaseXXX.php:
Holds the definition of your models so that Doctrine is able to handle the operations on the database. This class tells the ORM what colums are available, their types, advaned functions (like Timestampable,...) and more. You should not put your own data into this file since it will be over-written when re-creating the models from the database.
XXX.php:
Your actual model. This won't be re-created with each new generation process and this is were you keep most of your code. You can overwrite functions of the BaseXXX.php if you have to.
XXXTable.php:
Check my link from the top, This gives you access to the table itself. Personally, I do not use it that often since I put most of the code into XXX.php.
Of course you can create new classes and use them inside your XXX.php file. In order to actually do something with the data (save, read,...) you need classes that are connected (exteneded) from Doctrine's classes.
edit: also check this on a more infos with extending from the Doctrine_Table class
I have created a custom entity in MS CRM 4.0 and am trying to update a couple of the attributes via a custom worflow in .Net. I have read through several of the forums and blog posts and am still confused on how to access the custom entity and update some of their attributes.
I created a custom entity to replace how CRM was doing allotments as our company has some specific business rules that CRM wasn't doing. When a task is completed on an incident I want to update an attribute in the custom entity with the task duration. Any help would be greatly appreciated.
Thanks
When using the CRM web service in a custom workflow, you'll need to use DynamicEntity objects. The workflow context webservice is just an ICrmService so it doesn't know about your specific customizations. There's a pretty sample here: http://www.stunnware.com/crm2/topic.aspx?id=CustomWorkflowActivity
I imagine you could also add the CRM web services as a web reference to your workflow project. Then you'd have strongly types objects for your custom entities. I've never done this for my custom workflows, but it works for other custom apps accessing CRM.
Choosing Dynamic Entities over WSDL in favour is always the better choice.
When you develop a piece of code, you are more flexible with your classes. You could use your piece of software in different contexts for different systems. That's the reason Dynamic Entities were invented.
It's very easy and you dont'have to use DynamicEntity. You have to go to Settings -> Customization -> Download WSDL. Take the wsdl and use it in your project. Now you have all your custom entities strongly typed. All you have to do is to write something like this:
Guid entityId = getEntityId();
new_yourCustomEntity entity = new new_yourCustomEntity();
entity.new_yourCustomEntityid = entityId;
entity.new_customProperty = "value";
CrmService crmService = new CrmService();
crmService.Update(entity);
Maybe what you really mean is Custom Workflow Activity? This involves writing your own .NET class to add functionality to the standard CRM WF in form of new step types. If what you want to do is just to update an attribute you don't really need this, even if it is on a custom entity. The Update record step does just this and allows dynamic values (coming from other entities) to be specified.
Hope it helps
