'HttpRequest' does not contain a definition for 'EnableRewind' - asp.net-core

Question

I am trying to use the EnableRewind method in a custom authorization handler which I have created but i am getting the error "'HttpRequest' does not contain a definition for 'EnableRewind'" I need to access body in it but if I do it as shown in code I get the error in the controller "The input does not contain any JSON tokens. Expected the input to start with a valid JSON token,...." this is my handler i have injected IHttpContextAccessor from the startup file
public class ForPrivateProfileBodyMustOwnRecordOrShouldBeInAdminRoleHandler : AuthorizationHandler<ForPrivateProfileBodyMustOwnRecordOrShouldBeInAdminRole>
{
private readonly IHttpContextAccessor _httpContextAccessor;
public ForPrivateProfileBodyMustOwnRecordOrShouldBeInAdminRoleHandler(IHttpContextAccessor httpContextAccessor)
{
_httpContextAccessor = httpContextAccessor;
}
protected override Task HandleRequirementAsync(AuthorizationHandlerContext context,
ForPrivateProfileBodyMustOwnRecordOrShouldBeInAdminRole requirement)
{
var reader = new System.IO.StreamReader(_httpContextAccessor.HttpContext.Request.Body);
var body = reader.ReadToEndAsync().Result;
//this line is producing error
var req = _httpContextAccessor.HttpContext.Request.EnableRewind();
var request = Newtonsoft.Json.JsonConvert.DeserializeObject<PrivateProfileModel>(body);
var ownerId = context.User.Claims.FirstOrDefault(c => c.Type == "sub")?.Value;
if (request.UserId.ToString() != ownerId && !context.User.IsInRole("Admin"))
{
context.Fail();
return Task.CompletedTask;
}
//all checks pass
//_httpContextAccessor.HttpContext.Request.Body.Seek(0, System.IO.SeekOrigin.Begin);
context.Succeed(requirement);
return Task.CompletedTask;
}
}

finally i have resolved this issue actually the issue was the particular stream that ASP .NET Core uses –Microsoft.AspNetCore.Server.Kestrel.Internal.Http.FrameRequestStream – is not rewindable (found this article quite helpful http://www.palador.com/2017/05/24/logging-the-body-of-http-request-and-response-in-asp-net-core/) so solved it by creating new stream and placing it in body like this :
var body = reader.ReadToEndAsync().Result;
var request = Newtonsoft.Json.JsonConvert.DeserializeObject<PrivateProfileModel>(body);
using (var injectedRequestStream = new MemoryStream())
{
var bytesToWrite = System.Text.Encoding.UTF8.GetBytes(body);
injectedRequestStream.Write(bytesToWrite, 0, bytesToWrite.Length);
injectedRequestStream.Seek(0, SeekOrigin.Begin);
_httpContextAccessor.HttpContext.Request.Body = injectedRequestStream;
}
