Asp – .NET Runtime 2.0 Error in a service

.net-2.0.net-3.564-bitasp.netnet

We have a custom service that writes to a DB (SQL 2005). This is a full 64-bit environment (DB, .NET service). On one of our servers we crash every morning when we have a spike in our volume of data. On another server we run fine. The only differences that I've been able to notice between the two machines is that the one experiencing the crash has .NET 3.5 also installed.

Has anyone else seen this type of behavior?

Here is the event log entry from the crash today:

Have you tried to attache a debugger to the running code before the crash? Maybe you can track down where the problem is.

You could also use adplus to get a dump of the process and then use that dump in windbg to help track down the problem. Something like this should give you the dump file you are looking for:

adplus -crash -pn servicehost.exe

C# – Sending email in .NET through Gmail

Be sure to use System.Net.Mail, not the deprecated System.Web.Mail. Doing SSL with System.Web.Mail is a gross mess of hacky extensions.

using System.Net;
using System.Net.Mail;

var fromAddress = new MailAddress("from@gmail.com", "From Name");
var toAddress = new MailAddress("to@example.com", "To Name");
const string fromPassword = "fromPassword";
const string subject = "Subject";
const string body = "Body";

var smtp = new SmtpClient
{
    Host = "smtp.gmail.com",
    Port = 587,
    EnableSsl = true,
    DeliveryMethod = SmtpDeliveryMethod.Network,
    UseDefaultCredentials = false,
    Credentials = new NetworkCredential(fromAddress.Address, fromPassword)
};
using (var message = new MailMessage(fromAddress, toAddress)
{
    Subject = subject,
    Body = body
})
{
    smtp.Send(message);
}

Additionally go to the Google Account > Security page and look at the Signing in to Google > 2-Step Verification setting.

If it is enabled, then you have to generate a password allowing .NET to bypass the 2-Step Verification. To do this, click on Signing in to Google > App passwords, select app = Mail, and device = Windows Computer, and finally generate the password. Use the generated password in the fromPassword constant instead of your standard Gmail password.
If it is disabled, then you have to turn on Less secure app access, which is not recommended! So better enable the 2-Step verification.

C# – How to escape braces (curly brackets) in a format string in .NET

For you to output foo {1, 2, 3} you have to do something like:

string t = "1, 2, 3";
string v = String.Format(" foo {{{0}}}", t);

To output a { you use {{ and to output a } you use }}.

Or now, you can also use C# string interpolation like this (a feature available in C# 6.0)

Escaping brackets: String interpolation $(""). It is new feature in C# 6.0.

var inVal = "1, 2, 3";
var outVal = $" foo {{{inVal}}}";
// The output will be:  foo {1, 2, 3}
