    Hi, IRepository doesn't inherit from IQueryable anymore. (See related blog post) So you need to obtain IQueryable for your repository to be able to use LINQ methods, the recommended way is using IRepository.GetQueryableAsync() to obtain an IQueryable.

    • So you can change your code as below.
    var queryable = await Repository.GetQueryableAsync(); //obtain IQueryable
    var query = queryable.Include(r => r.LayerFields).Where(a => a.LayerName.Equals(tempLayerDto.LayerName));
