How to upgrade applications to version 2.X

In order to install the packages of WebMarkupMin version 2.X you need to upgrade the NuGet Package Manager to version 2.8.6 or higher.

If you develop ASP.NET Core 1.X application, then you need to start from scratch. About how to do this read in “ASP.NET Extensions” and “ASP.NET Core 1.X” sections of the documentation.

The main breaking change of WebMarkupMin version 2.X was refusal from the usage Web.config and App.config files for configuring of the core and other modules. Now during configuration instead of the declarative approach (using the configuration file) is used in the imperative approach (using the program code).

Therefore, when upgrading WebMarkupMin to version 2.X always need to do 2 things:

1. Uninstall a WebMarkupMin.ConfigurationIntelliSense package, because it has become useless.
2. After uninstall of obsolete packages and upgrade of old packages, you must remove the webMarkupMin configuration section group and its declaration from the Web.config and App.config files:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>
        …
        <sectionGroup name="webMarkupMin">
            …
        </sectionGroup>
        …
    </configSections>
    …
    <webMarkupMin xmlns="http://tempuri.org/WebMarkupMin.Configuration.xsd">
        …
    </webMarkupMin>
    …
</configuration>

Next, consider the upgrade procedure for each package:

Core

After upgrading of the WebMarkupMin.Core package you need in application code to replace all usings of WebMarkupMin.Core.Minifiers and WebMarkupMin.Core.Settings namespaces by WebMarkupMin.Core namespace.
