Delegates allow you to write code that can dynamically change what kills mealybugs on succulents methods that it calls. Set the name of the web form to index.

NET Framework directory. NoTracking option.

If you are using the Entity Framework EFthen you need to understand the best practices for improving its performance, or you will what is a meaning post mortem the consequences! My team has spent almost two years with the first version of the Entity Framework in an enterprise application including the beta.

NET 3. During development, we ran into significant issues with performance which we overcame by finding and following several best practices. The intent of this article is to explain those practices. This article assumes that you are familiar with what the EF is and how to use it. All of our Entity Framework calls were contained in our Web Service projects. Many of our EF calls took 8. Conhection making certain changes see the chart below to our Web Service projects, we were able to improve these calls to 3 seconds.

Second EF calls became almost instant. The chart below gives an indication of the overall performance impact srring respect to the EF and the level of refactoring it took us to implement the change. During View Generation, the store views are created. Fortunately, we can eliminate the expense of building the in-memory view by running the How to declare connection string in c# windows application generator EdmGen.

Running this tool will create a code file either. Having the view pre-generated reduces the startup time considerably. Every time the EF ObjectContext is created, the view must be generated, so pre-generating the view and deploying it with your application is important. The disadvantage of doing this is that you must keep the generated views synchronized with any changes you make to the data model.

The EdmGen. NET Framework directory. You can also access the EdmGen. In order to get the input. All options shown are required:. The Entity Framework can handle larger entity data models but you can run into performance problems if the data model is very inter-connected. In general, you should start thinking about breaking up a data model into multiple. The size of the. As the size of close relationship meaning in hindi schema files increase, the time it takes to parse and create an in-memory model for this metadata will also increase.

As stated earlier, this is a one-time cost incurred per ObjectContext applicatio and can be shortened by pre-generating the view. The designer cojnection starts to suffer from poor is it normal to argue every day when the number of entities gets too how to declare connection string in c# windows application. The disadvantage of paplication several smaller data models is that you must keep the individual.

Once the View Generation cost is eliminated, the most expensive operation is Object Materialization. When you are using the Entity Framework, you have objects that represent the tables in your database. These objects are created by an internal process called object materialization. This process takes the returned data and builds the relevant objects for you. The ObjectContext object will create an ObjectStateEntry object to help track changes made to related entities.

Objects are tracked when queried, added, or attached to the cached references inside this class. The tracking behavior is specified using the MergeOption enumeration. When updates to properties of the tracked objects occur, the properties are marked as modified and the original values are kept for performing updates back to the database. This enables users to write code against connfction objects themselves and call SaveChanges.

We can minimize the overhead of change tracking by using the MergeOption. NoTracking option. Doing so will increase the performance of your system in most situations. The loss of change tracking is irrelevant if you are sending your data across the network via a Web Service because this feature will not work in a "disconnected" mode. Even if you are not disconnected, you can use this option in a page where there are no updates to the database.

Take a look at the code snippet below for an example of how to disable change tracking:. It's unclear how much the MergeOption. NoTracking option connectkon performance because every query is different. In general, I would say it's certainly worth trying. Note, however, the following caveats exist when using the MergeOption. NoTracking option:. Some parts of the query are cached so that subsequent queries are faster than the first. However, not all parts of the query are cached, leaving some parts needing to be rebuilt each time the query is executed unless you are using eSQL.

We can eliminate the need for rebuilding now plans by using Compiled Queries. To compile a query for later, you can use the CompiledQuery. Compile method which uses a delegate:. You can direct the framework to eagerly load relationships by using an. Include statement as seen in the section above. With an eager load, the framework will construct a join query and the relationship data will be fetched along with the original entity data.

This can be avoided by using a. Load why wont my calls go through to one person to lazy load the relationship. With lazy loading, an additional query is constructed and run for each call to load to fetch the relationship information. Note that in certain instances, eager loading is better while in others, lazy loading is a better approach.

Include statement can result in a large amount of data being brought back, it can also result in complex queries because of the need to use many Join statements at the data store. In the code below, every table that has a relationship to the specified table will be loaded. The ObjectContext object retrieves connection information automatically from the application config file when creating object queries. You can supply this named connection string instead of relying on the connectionString parameter in the.

The Metadata property in the connectionString parameter contains a list of locations for the EntityClient provider to search difference between aggregation and composition relationship EDM mapping and metadata files the. Mapping and metadata files are often deployed in the same directory as the application executable file.

These mapping files can also be included as an embedded resource in the how to declare connection string in c# windows application which will improve performance. In order to embed the EDM mapping files in an assembly, you need to do the following:. To improve performance, always specify the assembly name instead of the wildcard. Applicatioh is an excerpt from a web. You can see the metadata property is specifying the assembly name MyApp. Special thanks to Alex Creech for crunching the numbers in the Visual Studio Profiler and writing much of our Entity Framework helper code!
