Weixin.WxOpen.AdvancedAPIs.TemplateApi下调用同名接口！

Error message

Weixin.WxOpen.AdvancedAPIs.TemplateApi下调用同名接口！

What it means

TemplateApi.LibraryList in Senparc.Weixin.Open's WxaAPIs is a stub: it is marked [Obsolete] and immediately throws WeixinObsoleteException. The real implementation moved to the mini-program module Senparc.Weixin.WxOpen.AdvancedAPIs.TemplateApi.LibraryList.

Solutions

1. Replace the call with Senparc.Weixin.WxOpen.AdvancedAPIs.TemplateApi.LibraryList(accessToken, offset, count, timeOut).
2. Fully qualify or fix using directives so the WxOpen TemplateApi is imported, not the Open one.
3. Remove references to the obsolete Open-module template APIs — they will always throw.

Example fix

// before
var list = Senparc.Weixin.Open.WxaAPIs.TemplateApi.LibraryList(accessToken, 0, 20);
// after
var list = Senparc.Weixin.WxOpen.AdvancedAPIs.TemplateApi.LibraryList(accessToken, 0, 20);

var flags = typeof(Senparc.Weixin.Open.WxaAPIs.TemplateApi)
    .GetMethod(nameof(Senparc.Weixin.Open.WxaAPIs.TemplateApi.LibraryList))?
    .GetCustomAttributes(typeof(ObsoleteAttribute), false);
bool isObsoleteStub = flags != null && flags.Length > 0; // use WxOpen module instead

try { var r = Open.WxaAPIs.TemplateApi.LibraryList(token, 0, 20); }
catch (WeixinObsoleteException) { r = WxOpen.AdvancedAPIs.TemplateApi.LibraryList(token, 0, 20); }

When it happens

Trigger: Calling the old Senparc.Weixin.Open.WxaAPIs.TemplateApi.LibraryList(accessToken, offset, count) — any call throws, there is no working code path.

Common situations: Upgrading Senparc.Weixin.Open where the method was gutted; old code samples referencing the Open-module TemplateApi; IDE auto-imports picking the wrong namespace (Open vs WxOpen).

Understand the failure class

Background: "is deprecated and will be removed" — deprecation warnings for old API names, keywords, and options, and how to migrate before the removal release — this error's family across 29 libraries.
