ASP.Net Core 发布失败，原因是无法复制该文件。

Question

我正在尝试将一个 WebJob 发布到 Azure 上，但是我遇到了如下的一些错误。看起来是因为在“Out”后面的路径中它添加了两个反斜杠而不是一个（PubTmp\Out\\app_data）。

在我的情况下，问题是项目路径太长了。似乎有一个256个字符的限制。它可以使用“Debug”配置文件，但不能使用“Release”配置文件，因此我将项目路径缩短到256个字符以下，现在它可以工作了。 - Popa Andrei

Answer 1

可能是发布路径太长了。

以下是我所做的步骤：

1. 重命名您的项目（使其更短）。
2. 如果其他项目引用了您重命名的项目，请修复它们的依赖项。
3. 重命名包含项目的文件夹。
4. 从解决方案中删除项目，然后再添加它（也可修复引用问题）。
5. 删除发布配置文件。
6. 清理并重新构建。
7. 创建一个新的发布配置文件。

如果这不起作用，可能是路径仍然太长。

祝好运。

Answer 2

你可能只需要下载文件并使用第三方程序上传它。如果你从代码中下载文件，请确保在代码开头放置以下代码。希望这能起作用！

Answer 3

我遇到了同样的问题，一切都正常工作，但在尝试从Visual Studio发布WebJob时，没有更改任何内容，我仍然收到相同的错误。

我通过将目标框架更改为.Net 5.0而不是Net Core 3.1来解决了这个问题。

以下是我用来解决问题的步骤：

1. 右键单击项目，然后在目标框架下拉菜单中选择.NET 5.0。
2. 清理项目
3. 关闭Visual Studio
4. 手动删除obj和bin文件夹
5. 打开Visual Studio
6. 右键单击项目，然后选择重新生成

当所有内容成功编译时，请再次尝试发布-它应该可以工作。

如果您的依赖项尚未与.NET 5.0兼容，我建议您降级到net core 2.0（按照上述步骤）然后再将其更改回net core 3.1（按照上述步骤）。

我不知道为什么会发生这种情况，但至少对我有效。
