Pushing Your First .NET Core 1.0 RTM Apps to Cloud Foundry and PCF Dev

Pushing a .NET Core 1.0 RTM application to Cloud Foundry is a fairly straightforward process.

Follow the instructions at https://www.microsoft.com/net/core to get your development machine installed with all the necessary binaries, and create the "Hello World" application as they show you on that page.

Next, go to https://docs.asp.net/en/latest/getting-started.html and either create a new project as that page shows you or modify your "Hello World" app from earlier using the instructions on that page.  Run your app locally per the last couple instructions on that page to make sure it works.

Next, we need to make some slight tweaks to the application to work better with Cloud Foundry.  Follow the instructions at https://github.com/cloudfoundry-community/dotnet-core-buildpack#using-samples-from-the-cli-samples-repository to add a dependency to your project.json to allow configuration of the Kestrel server via command line arguments.  You will also modify your Main method in the project to wire in the command line arguments to a Configuration object, and also make sure that the WebHostBuilder uses that new configuration.

Finally, push your application to Cloud Foundry using the following command (replacing SOME_APP_NAME with your own app name):

cf push SOME_APP_NAME -b https://github.com/cloudfoundry-community/dotnet-core-buildpack

Note: If you are using PCF Dev to test this in a local install of Cloud Foundry (at least with version 0.16.0) you will need to raise the size of the disk quota for the container to 1G.  You can do that by using the following to push your app:

cf push SOME_APP_NAME -b https://github.com/cloudfoundry-community/dotnet-core-buildpack -k 1G

Using Snapshot Isolation with SQL Server and Hibernate

In the course of working on some deadlock issues, I found that MS SQL Server exhibits some unexpected (to me, at least) locking behaviors that can affect performance and cause deadlocks. In the end, I found that SQL Server provides an isolation level called Snapshot isolation which removes the need for locks on rows and removes lock contention. To use this isolation level, you need to execute the following SQL on the database that you want to use the isolation level with (replacing MyDatabase with your database name, of course): ALTER DATABASE MyDatabase SET ALLOW_SNAPSHOT_ISOLATION ON ALTER DATABASE MyDatabase SET READ_COMMITTED_SNAPSHOT ON Next, you need to modify your hibernate.cfg.xml file to add a property to tell Hibernate to use the Snapshot Isolation level: <!-- The 4096 isolation level is the setting to use with the jTDS or Microsoft JDBC drivers --> < property name =”hibernate.connection.isolation”>4096</property> Snapshot isolation is not a panacea...

FreeNAS, CIFS, and user login problems

Image
I have been in the process of converting from the dead-end Windows Home Server product to a FreeNAS server for my home NAS.  I was trying to replicate the same sort of set up that WHS had for user directories.  In WHS, there was a share called "Users" and under that share there were various user directories corresponding to each user account.  I thought it would be pretty simple to replicate that same behavior to allow users to simply attach to \\nas-server-name\Users in Windows, and then navigate to their own user folder.  What follows is how I achieved this, as well as a problem I fought with for a while that prevented certain users from connecting via CIFS. First, I started off the process by installing FreeNAS to a USB stick, added a few disks in the server, plugged in the USB stick and booted up.  I performed basic config for the networking, and admin account passwords, and turned on the CIFS service. Next, I created a some user accounts fo...

Official Pandora Desktop and Hotkey Support?

EDIT: There is a slight problem occasionally with this script not being able to send keys to the Pandora Desktop Air app. I've got an updated version of the script that you can use instead of this one. Pandora is a different sort of online music service that uses the work of the Music Genome Project to automatically selects music similar to an artist or particular song, and then streams it over the Internet for your listening pleasure. You can't select individual songs, but you can skip ones you don't like and make as many music channels as you like to suit your particular tastes. Pandora provides a free version of the product that is supported by visual advertising, and a very inexpensive ($36 USD per year as of the creation of this entry) subscription supported version of the product that provides higher quality streams and no advertising. Traditionally, Pandora has been a Flash-based application that required you to have your bulky browser open to listen on the deskto...
