MongoDB C# Driver Cheat Sheet

As of releasing MongoDB 3.4 and C# Driver v2.4, original cheatsheet by Derek is outdated. In addition, it has some deficiencies like connecting to MongoDB, creating indexes, etc. This updated version works fine with C# Driver v2.4.7 and MongoDB v3.4.

Define Document Models

Note: Defined models and collections will be used in entire cheatsheet.

Hello software developers,

Please check your code to ensure you're not making one of the following mistakes related to cryptography.

I. General Mistakes

Writing your own home-grown cryptography primitives (For example: Mifare Classic)
- Exception: For the sake of learning, but don't deploy it in production.
Using a fast hash function (e.g. MD5, SHA256) for storing passwords. Use bcrypt instead.
Not using a cryptographically secure random number generator

MS Office prefixed style properties

mso-ansi-font-size

Note: Office only

mso-ansi-font-size: large | larger | <length> | medium | <percentage> | small | smaller | x-large | x-small | xx-large | xx-small

Expose IIS or IISExpress running in a Parallels Windows 7/8 VM to your OS X host

Rename your virtual machine

In your Windows 7/8 VM, go to Control Panel > System > Advanced system settings > Computer Name and click Change. Name this whatever you like, e.g. windows. Restart your VM.

Add an ACL rule

Open CMD or Powershell as administrator. Add a URL ACL entry for your new name on the port of your choice, e.g.
netsh http add urlacl url=http://windows:8080/ user=everyone

Add a firewall rule

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
