A quick round-up of some useful LINQ to SQL related resources that are available for developers. I’ve not used everything on this list myself so don’t take this as personal endorsement.
- Entity Developer
Add-in for Visual Studio that provides a replacement designer with code templates. Commercial ($99.95)
- LLBLGen Pro
This ORM templating and design tool has a set of LINQ to SQL templates available for generating C# code including file per entity that can be used in conjunction with their designer. Templates are free but require LLBLGen Pro licence (€179-249).
My templates use Visual Studio’s built in T4 engine and provide a great starting point to customizing the code generation process. Everything that SQL Metal/LINQ to SQL designer can generate is handled including C# and VB.NET generation and are freely licensed under the MS-PL.
These templates for Eric Smith’s ever-popular CodeSmith templating environment include a whole host of extra functionality beyond the standard generation including entity clone & detach, enum’s from tables, data annotations, batching, auditing and more. Templates are free but require CodeSmith licence ($79-$299).
- T4 Toolbox
Oleg Sych has put together a suite of useful T4 templates including ones for producing LINQ to SQL entities, data contexts as well as SQL scripts for altering the schema to reflect changes. C# only, MS-RL.
Note: While the T4 templating language is built-in to Visual Studio 2008/2010 it does not come with syntax highlighting or IntelliSense. Check out either:
- Clarius Visual T4
Basic ‘community’ version available for free, commercial ‘pro’ version with IntelliSense, sub-templates, preview, user preferences etc. is $99.
- Tangible T4
Free version available with limited IntelliSense, commercial ‘pro’ version with UML modelling etc. available for $99.
