Weekly Update: CodeSmith Generator, Serilog Sink, and Foundatio.Redis Updates

Blake's been busy lately, including some work on one of our other projects, CodeSmith Generator, to update Exceptionless to the latest version. Naturally, this got him thinking about other potential improvements while we were doing work on Serilog Sink for Exceptionless and Foundatio.Redis, as well.

Watch the video to hear the full story!

CodeSmith Generator Gets Latest Exceptionless Update #

While updating our WPF application, CodeSmith Generator, to the latest version of Exceptionless, Blake brainstorms several improvements that could be made to help take advantage of plugins, isolate Exceptionless from other plugins, etc.

Serilog Sink #

There was an issue that was breaking the ability to update to the latest version of Exceptionless. This has now been fixed.

Foundatio.Redis Update #

Deserialization wasn't working properly with binary serializers, but the issue has been resolved.


More Improvements to Exceptionless Slack Integration

In this week's video, Blake covers a quick update on the Exceptionless Slack integration, along with a minor update to Foundatio.

Take a look!

Slack Integration Update #

We have been tweaking the recent Slack integration over the past month or so, and this week we noticed that action URLs being created incorrectly and failures weren't being handle correctly with rate limiting. So, those two issues have been tweaked and should be working much better now.

In Foundatio News #

A big shout out to @pwelter34 for submitting a pull request that added support for Serilog to Foundatio - Paul!

Exceptionless Slack Integration, Further Improved Notifications

As you guys know, we've been working on notification improvements lately. This latest video update by Blake is no different and involves Slack integration!

If you're not familiar with Slack, definitely check it out. It's a great app for communicating with your team, and much more. For Exceptionless, it's been something we've wanted to integrate closely with for a while now, because email can be very tedious and overwhelming. With Slack integration, you can set up a specific channel for your Exceptionless notifications to go to, and have an organized eye on your events.

Watch the video above for an explanation of the integration, and see below on how to set it up for yourself.

Set up Slack Notifications for Exceptionless #

First, go into your project's settings in the Exceptionless app and click on the Integrations tab.


Then, click on "Add Slack Notifications" and log in to your slack team.

Once logged in, you will need to select the channel you want Exceptionless Notifications to post to and click Authorize.

Once authorized, you can then configure the different notification settings by going back to the Exceptionless app and into the project's integrations tab again.


Once integrated and configured, notifications will look something like the below screenshot, with the message, type of event, stack trace, links to actions, etc.

We're excited to keep improving notifications, and would love for you guys to test this out for us.

Integrations with other chat & productivity tools like HipChat and Microsoft Teams are on our list, as well, so if you use these please ping us and let us know so we can gauge interest!

Email Notification Improvements - Walkthrough and Details

exceptionless email notifications

Recently, we made several improvements to our email notifications, adding additional details, improving rendering, and more. Blake has mentioned it in a few of his weekly update videos, but today we wanted to walk you through it and add a few more details, with examples. Check it out!

Exceptionless Email Notification Implementation #

We decided to use Zurb's Foundation for Emails to help us create emails that look great on all email clients. The reason we went with Zurb is because it has clean markup that translates to good old (ugly) HTML that just works. It also works great with Handlebars.Net which we use to render the email content.

An example of one of our event notification emails can be found here.

Then, we run a Node.js build task to transform the templates into some pretty crazy html markup that works everywhere. The markup at that link contains the Handlebars.Net syntax.

These templates are stored as embedded resources so we can use them from any environment and render them out with ease! Here is a code example of how we perform that task.

We added JSON-LD support, to the emails to give us rich contextual actions, by starting with this Google Developer tutorial and ended up with the below implementationIt's worth noting that we had to go through their verification process for the actions to be enabled.

<script type="application/ld+json">
"@context": "",
"@type": "EmailMessage",
"description": "\",
"potentialAction": {
"@type": "ViewAction",
"target": "\/event/\",
"url": "\/event/\",
"name": "View Event Details"
"publisher": {
"@type": "Organization",
"name": "Exceptionless",
"url": "",
"logo": ""

We tested the emails in Outlook for Windows and Mac, Paper Cut, Gmail on Safari, and Apple Mail. Then, we used Litmus to test a wide range of clients before publishing and pushing everything live.

Questions? Comments? #

We hope our build out here can help other developers, and we would love to hear your feedback, questions, or comments either here on the blog or over on GitHub!

Code on.

In this week'd update, Blake does a little traveling and speaking, and both Exceptionless and Foundatio.Repositories get an update!

Exceptionless & Foundatio.Repositories Updates #

For Exceptionless, we worked on upgrading the email templates to use Zurb for emails and handlebars. We also fixed an issue where you could only log in 15 times in a 15 minute time period.

The only really notable thing we did for the .NET client is fix the ProcessQueue method, making sure it blocks until the queue has been processed.

Exceptionless.JavaScript Client Update #

For our JavaScript client, we want to work on supporting universal apps, but first we have to upgrade to the latest version of TypeScript, so we did some work this week toward that.
