Updating dbml files dating a pilot in hong kong

One such tool is my add-in, Huagati DBML/EDMX Tools.

It adds a bunch of features to the L2S designer in VS2008 and VS2010, including update/sync, comparison, mass-renaming, name rule enforcement, documentation from extended properties/indexes/etc, multiple 'views' per dbml diagram etc. I did it by opening the cmd prompt, and directing the path equal to the Sql path.

Though this is manual process but it really helps you a lot.

Really stupid question, sorry, but I can't find it on google (I'm sure it's in a screencast or something somewhere).

It does not support Xml Serializer or Binary Formatter. This approach eliminates the name/namespace collision. I get an error when I drag tables out of a SQL Server Compact 3.5 database. The Object Relational Designer does not support SQL Server Compact 3.5, although the LINQ to SQL runtime does. You must provide information such as the discriminator column, base class discriminator value, and derived class discriminator value.

Code generation in LINQ to SQL supports Data Contract Serializer serialization. When I have multiple DBML files that share some tables in common, I get a compiler error. Set the Context Namespace and Entity Namespace properties from the Object Relational Designer to a distinct value for each DBML file. In other cases, you should manually set Is Db Generated= Q.

I have a DBML (linq2sql classes) diagram and I've changed the underlying database. There's no View--That doesn't update the DBML file with database changes.

It triggers the code generator that generates C# or VB code from the DBML file.

curious if there is a better way, but this works quick so that's what we do.

Note also that LINQ to SQL requires the Named Pipes protocol to be enabled. If you expect to take time to process all the results and are not opposed to caching the results, apply To List to the query. LINQ to SQL provides several tools for inspecting the SQL code it generates.

Make sure your connection string is correct and that your SQL Server instance is running. A connection typically remains open until you consume the query results.

The only workaround I have found is to delete the stored procedure, then delete the table that the stored procedure returns, add the table then add the stored procedure (all in the . You could either investigate a third-party tool like the DBML Tools by Huagati to solve this, or switch to Entity Framework 4 which has much better support for updating your existing model from the database when the underlying database has changed.

Thanks in advance The DBML visual designer is very much a "one shot" thing - there's no update functionality of any kind.

I have a stored procedure whose return value is calculated by For more information, see Customizing Operations By Using Stored Procedures. When I try to serialize, I get the following error: "Type ' System.
