The namespace "TypeProviders" is not defined (open Microsoft.FSharp.Data.TypeProviders)

Question

I'm walking through Visual Studio's F# tutorial project. When I uncomment the "OData" module (which is very simple, similar to this MSDN walkthrough), the first line here

open Microsoft.FSharp.Data.TypeProviders
type Northwind = ODataService<"http://services.odata.org/Northwind/Northwind.svc/">
// ...

indicates this compiler error:

The namespace "TypeProviders" is not defined

The error remains after adding a reference to "FSharp.Data.TypeProviders" and "System.Data.Services.Client".

What am I doing wrong here?

• McGarnagle: @abatishchev no compiler warnings, apparently... there is another error that does not seem related to resolving the library reference: The type provider 'Microsoft.FSharp.Data.TypeProviders.DesignTime.DataProviders' reported an error: Error reading schema. The remote server returned an error: (400) Bad Request.
• Alexan: try open FSharp.Data instead Microsoft.FSharp.Data.TypeProviders
• McGarnagle: @Alex "FSharp..." is the name of the assembly, the namespace is "Microsoft.FSharp..." msdn.microsoft.com/en-us/library/hh362324.aspx
• Alexan: okay, maybe it's because I used Freebase Provider from this library: fsharp.github.io/FSharp.Data, but it doesn't include OData.
• Alexan: install FSharp.Data.TypeProviers nuget. Probably you're missing some reference, maybe policy.2.3.FSharp.Core

Answer 1

Okay, you need to create new project, then add FSharp.Data.TypeProviers nuget to this project and the following code should work:

open Microsoft.FSharp.Data.TypeProviders
type Northwind = ODataService<"http://services.odata.org/Northwind/Northwind.svc/">
