由于无法复制文件，ASP.Net Core 发布失败

Question

我正在尝试将 webjob 发布到 Azure，但出现一些如下错误。看起来是因为在“Out”之后的路径中它添加了两个反斜杠而不是一个（PubTmp\Out\\app_data）。

Further technical details

我正在使用 ASP.Net Core 3.1 和 Visual Studio 2019

Answer 1

可能是发布路径太长。

以下是我所做的步骤：

1. 重命名您的项目（使其更短）。
2. 如果其他项目引用您重命名的项目，请修复它们中的依赖项。
3. 重命名包含项目的文件夹。
4. 从解决方案中删除项目并再次添加（也是为了修复引用）。
5. 删除发布配置文件。
6. 清理并重建。
7. 创建新的发布配置文件。

如果没有帮助 - 可能是游览路径仍然太长。

祝你好运。

Answer 2

我遇到了同样的问题，一切正常，无需更改任何内容，在尝试从 Visual Studio 发布网络作业时遇到相同的错误。

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

以下是我解决问题所遵循的步骤：

1. 右键单击该项目，然后在目标框架下拉列表中选择 .NET 5.0。
2. 清理项目
3. 关闭视觉工作室
4. 手动删除文件夹 obj 和 bin
5. 开放视觉工作室
6. 右键单击该项目并选择“重建”

当一切编译成功后，尝试再次发布 - 它应该可以工作。

如果您的依赖项尚不兼容 .NET 5.0，我建议您降级到 net core 2.0（按照上述步骤），然后将其改回 net core 3.1（按照上述步骤）。

我不知道为什么会这样，但至少这对我有用。
