无法解析来自名为“ xyz.dacpac”的源中的外部元素的引用

Question

我正在使用Microsoft.SqlServer.Dac.dll以编程方式部署我的dacpac。即使我在目标位置包括了所有供参考数据库项目使用的dacpac，我仍然得到“无法解析来自名为'xyz.dacpac'的源中对外部元素的引用”。

最终，部署失败。下面是堆栈跟踪。

ERROR : The reference to external elements from the source named 'xyz.dacpac' could not be resolved, because no such source is loaded.

Answer 1

通常，这是引用链接的问题。如果您有一个引用另一个（B.dacpac）的项目（A.dacpac），则显然需要在整个项目中包括B.dacpac。

但是，如果B.dacpac引用X.dacpac，Y.dacpac和ThirdParty.dacpac，则由于缺少引用，如果项目部署中未包含这些错误，则会出现错误。

但是，如果您实际上拥有A.dacpac和B.dacpac之间所需的所有项目，并且不需要引用X，Y或ThirdParty中的任何内容，则可以将项目A中的未解析引用抑制为是的，这些缺失的引用将被忽略。
