Map async result with automapper

Question

We are createing a Web.Api application of a angularjs application. The Web.Api returns a json result.

Step one was getting the data:

    public List

        

Answer 1

You need to move the async data fetch out of the Map call:

var data = await dataRepository.GetDataAsync();
return Mapper.Map>(data);

Alternatively, you can use AutoMapper LINQ projections:

var data = await dbContext.Data.ProjectTo().ToListAsync();

I don't know if your repository exposes IQueryable directly (we don't use repositories). Our apps use the second version pretty much exclusively these days.
