How to create SVN branch from trunk

Submitted by Asif Nowaj, Last Modified on 2019-11-08

SVN Trunk code should always be the production copy of the codebase. At least this is how I see it.

When a new project work starts an existing application or required a significant amount of code change then you might need to create a separate branch from working production copy of the code. Apart from that, there could be many other reasons to create separate SVN branch from trunk like multiple team, parallel work etc.

jsTree is jquery plugin, that provides interactive trees. jsTree is easily extendable, themable and configurable. One of noticeable feature is its unique node name. This plugin enforces that no nodes with the same name can coexist as siblings. This plugin has no options, it just prevents renaming and moving nodes to a parent, which already contains a node with the same name.

If you are migrating your application where Entity Framework 5.0.0 (EF 5) is used, to latest .NET framework 4.8 from 4.6 range, then after upgrading your .NET framework, you will be advised to upgrade Entity Framework as well.

Once I upgraded Entity Framework to 6.2.0 (EF 6), we have encountered with some compilation issue. like below:

Operator '==' cannot be applied to operands of type 'EntityState' and 'EntityState'

Do not worry, this is not a huge change.
