Question

How can I add LINQ to SQL class (.dbml file) to Visual Studio 2017 RC. I can\'t find it. Please help, thanks.

By default VS 2017 installer doesn't provide LINQ to SQL tools while installing we have to select that and modify.

Follow easy steps from here:

Open VS2017 installer.

Go to Individual Components.

Select he LINQ To SQL tools from code tools.

and just modify.

SuperUser.com also contains a nice answer

Basically you need to modify your VS2017 installation and add the standalone Linq-to-Sql component.

Answer 3

Open Vs 2017 installer, go to individual components and check LINQToSQL component then click modify button.

Answer 4

​If, you use the DotNetCore. Linq to SQL doesn't show the option. To use Linq to SQL, you need to select DotNetFrameWork then you'll have an option to select Linq to SQL. It worked for me.

Answer 6

You need to opt in to enable the designer during installation, it is not enabled by default: https://developercommunity.visualstudio.com/content/problem/4616/linq-to-sql-dbml-designer-in-not-working.html

"Editing .dbml files with a designer surface requires the LINQ to SQL tools which are not installed by default as part of any of the workloads of Visual Studio 2017. It can be installed by selecting the 'LINQ to SQL tools' item under the 'Code Tools' category in the 'Individual Components' tab of the Visual Studio installer."
