[c#] WebForms UnobtrusiveValidationMode requires a ScriptResourceMapping for jquery

Further to the accepted answer, I ran into issues with code elsewhere on my site requiring jQuery along with the Migrate Plugin.

When the required mapping is added to Global.asax, when loading a page requiring unobtrusive validation (for example a page with the ChangePassword ASP control), the mapped script resource conflicts with the already-loaded jQuery and migrate scripts.

Adding the migrate plugin as a second mapping solves the issue:

// required for UnobtrusiveValidationMode introduced since ASP.NET 4.5
var jQueryScriptDefinition = new ScriptResourceDefinition
{
    Path = "~/Plugins/Common/jquery-3.3.1.min.js", DebugPath = "~/Plugins/Common/jquery-3.3.1.js", LoadSuccessExpression = "typeof(window.jQuery) !== 'undefined'"
};
var jQueryMigrateScriptDefinition = new ScriptResourceDefinition
{
    Path = "~/Plugins/Common/jquery-migrate-3.0.1.min.js", DebugPath = "~/Plugins/Common/jquery-migrate-3.0.1.js", LoadSuccessExpression = "typeof(window.jQuery) !== 'undefined'"
};
ScriptManager.ScriptResourceMapping.AddDefinition("jquery", jQueryScriptDefinition);
ScriptManager.ScriptResourceMapping.AddDefinition("jquery", jQueryMigrateScriptDefinition);
