I had same problem ad almost got mad. I tried everthing with no sucsses. First I found a workaround to solve part of my problem:

Workaround:

string data1 
string horainicio 
string horafim

var ageData = new AgendaData();
var user = await _userManager.GetUserAsync(User);
string usuario = user.Id;
int empresa = user.IdEmpresa;
int Idprospect = Convert.ToInt32(prospect);
int minutos = 0;           
var tipoAgenda = TipoAgenda.Contato;

var provider = CultureInfo.InvariantCulture;
provider = new CultureInfo("en-US");            
string formato = "dd/MM/yyyy HH:mm";

var dataInicio = DateTime.ParseExact(data1 + " " + horainicio, formato, provider);
var dataFim = DateTime.ParseExact(data1 + " " + horafim, formato, provider);           
var dataAlerta = dataInicio.AddMinutes(-minutos);

But, this way i aways have to set invariantculture to all my datetime. I found the solution setting my culture at the configure on startup.cs.

Set Culture on startup.cs

 public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, CRMContext context)
        {
            loggerFactory.AddConsole(Configuration.GetSection("Logging"));
            loggerFactory.AddDebug();

            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
                app.UseDatabaseErrorPage();
                app.UseBrowserLink();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
            }

            //Fixar Cultura para en-US
            RequestLocalizationOptions localizationOptions = new RequestLocalizationOptions
            {
                SupportedCultures = new List { new CultureInfo("en-US") },
                SupportedUICultures = new List { new CultureInfo("en-US") },
                DefaultRequestCulture = new RequestCulture("en-US")
            };

            app.UseRequestLocalization(localizationOptions);      
            app.UseStaticFiles();
            app.UseIdentity();

            // Add external authentication middleware below. To configure them please see https://go.microsoft.com/fwlink/?LinkID=532715

            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });

            context.Database.EnsureCreated();
        }

Hope this help you.
