Where ByteRangeStreamContent class in asp.net core? - asp.net-web-api

Question

I start writing project on asp.net core and I can not find class ByteRangeStreamContent.
Where is it?
Did it was removed from asp.net core?
Is there replacement of this class?
UPDATE 2016-10-06
dotnet --version
1.0.0-preview2-003131

Answer 1

Instead of using ByteRangeStreamContent you can now use the FileStreamResult or FileContentResult and set EnableRangeProcessing to true.
new FileStreamResult(new MemoryStream(bytes), new MediaTypeHeaderValue("audio/mp3"))
{
EnableRangeProcessing = true
};

Answer 2

Add this dependency in your project.json:
"Microsoft.AspNet.WebApi.Client": "5.2.2"
Then, you can use the class:
System.Net.Http.ByteRangeStreamContent
Another option is to write ByteRangeStreamContent to import automatically using Visual Studio:
My project.json is (the default when creating a new web api project):
{
"dependencies": {
"Microsoft.AspNet.WebApi.Client": "5.2.2",
"Microsoft.AspNetCore.Mvc": "1.0.0",
"Microsoft.AspNetCore.Server.IISIntegration": "1.0.0",
"Microsoft.AspNetCore.Server.Kestrel": "1.0.0",
"Microsoft.Extensions.Configuration.EnvironmentVariables": "1.0.0",
"Microsoft.Extensions.Configuration.FileExtensions": "1.0.0",
"Microsoft.Extensions.Configuration.Json": "1.0.0",
"Microsoft.Extensions.Logging": "1.0.0",
"Microsoft.Extensions.Logging.Console": "1.0.0",
"Microsoft.Extensions.Logging.Debug": "1.0.0",
"Microsoft.Extensions.Options.ConfigurationExtensions": "1.0.0"
},
"tools": {
"Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-preview2-final"
},
"frameworks": {
"net461": { }
},
"buildOptions": {
"emitEntryPoint": true,
"preserveCompilationContext": true
},
"publishOptions": {
"include": [
"wwwroot",
"Views",
"Areas/**/Views",
"appsettings.json",
"web.config"
]
},
"scripts": {
"postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ]
}
}
My dotnet version is the following:
C:\Users\fabriciopombo>dotnet --version
1.0.0-preview2-003121
And I'm using Visual Studio 2015 Update 3
