On localhost you are using a Sqlserver ado provider, but something else on the server.

Hi tadbirgaran,

Please try to remove any glimpse packages via nuget. Then "Clean" your solution and make sure that there are no Glimpse dlls in your bin/obj folders. Next remove anything Glimpse from your "Packages" folder. Once you have done this, clean your solution and reinstall Glimpse again.

Best Regards.

Thanks for reply

I do not want to reinstall it.
I did your steps. I just did not reinstall it at last. The following error message is given:

GlimpseSecurityPolicy.cs' could not be found.

You can't tell one object that it's going to be another object, the cast, becuase each object has its own blue print, the class that defines the object, and the blue prints do not match. It's OO 101 and it doesn't matter if it's Java or .NET the OO principles are the same.

Of course,  it's not going to work, becuase there is something wrong with your code that is trying to make a cast that it cannot do. Do you have a idea as to where it's going down by showing the code and/or stack trace on the code location where the exception is being thrown?

This problem was solved on the hosts, but on another local system it still made this error.
Is on the web.config Should I change? Glimps was on the Web.config
