Logged in user and Task.Run

Hi,

In version 3.0 I could do this:

public Task RunImportAsync(CancellationToken cancellationToken)
 {
 myCancellationToken = cancellationToken;

task = Task.Run(() =>
 {
 DoImport();
 });
 return task;
 }

In version 3.1 I must do this to preserve the logged in user for the code inside Task.Run:

public Task RunImportAsync(CancellationToken cancellationToken)
 {
 var impersonatedUser = Csla.ApplicationContext.User;
 myCancellationToken = cancellationToken;

task = Task.Run(() =>
 {
 Csla.ApplicationContext.User = impersonatedUser;
 DoImport();
 });
 return task;
 }

What do you think? Is there a setting or something I can do to make it work as before?

Best regards,
Wilfred
