发布时找不到错误的元数据文件dll CSC [英] Error Metadata file dll could not be found CSC when publishing

问题描述

我有一个Visual Studio解决方案，其中包含多个项目，特别是DotNet5 asp.net应用程序，上面有多个netstandard 2.0参考.它可以在调试器中构建并正常运行，但是会不断抛出元数据错误.在netstandard2项目中，它一直专门引用其寻找的net5文件夹.我找不到它的来源，这个有问题的项目曾经是针对框架4.7、4.8和net5.0的多目标项目，但是我对多个dll感到恼火，只是将其迁移到standard2.0，直到出现问题为止我要发布它.

I have a Visual studio solution with several projects in it, specifically a DotNet5 asp.net app, that has several netstandard 2.0 references on it. it builds and runs fine in the debugger but continuously throws the metadata errors. It keeps specifically referencing its looking for a net5 folder in the netstandard2 project. I cannot find where its getting this from, the problematic one used to be a multitargeted project against framework 4.7, 4.8, and net5.0, but i got annoyed with the multiple dll's and just migrated it to standard2.0 and had no issues till i want to publish it.

我已经尝试了其他一些参考问题，例如清理，重建，删除并重新添加对其他项目的引用，从解决方案中删除了obj和bin文件夹，删除了sou文件，尝试了VS 2019(16.9.0预览2)预览版vs 2019(16.8.3)发行版，不同的计算机(从lan git存储库中拉回)并出现相同的错误....还尝试在整个解决方案中搜索对net5.0的引用，但没有不能在预期位置之外找到它，例如asp.net项目的csproj及其相应的pubxml.只是为了好玩，我暂时将库项目重新定位为net5.0，即使列出的确切文件和路径确实存在，它仍然引发相同的错误.

I've tried what a few other questions referenced, cleaning, rebuilding, remove and re add references to other projects, deleted the obj and bin folders out of the solution, the removing the sou file, tried VS 2019 (16.9.0 preview 2) preview vs 2019 (16.8.3) release, different computer (pulled back down from a lan git repository) and got the same error.... also tried searching the entire solution for references to net5.0 and didn't find it outside of the expected locations like the csproj for the asp.net project and its respective pubxml. And just for fun, I temporarily retargeted the library project back to net5.0 and it still threw the same error even when the exact file and path listed did exist.

在错误消息中的不同列中使用以下错误输入，并删除了敏感"标记.信息.Visual Studio没有提供错误代码.其他人对尝试什么有更多的想法吗?

Using enters for the error below for the different columns in the error message, and removed the "sensitive" info. There is no error code provided by Visual Studio. Anyone else got any more ideas on what to try?

错误

添加错误消息的其他两个部分:

adding a couple other sections of the error messages:

===================

输出窗口的结尾，因为完整的东西太长了.仍然不知道从哪儿获得了net5.0可供一个项目参考

And the end of the output window since full thing is a bit too long. still can't figure out where its getting the net5.0 for the one project reference

推荐答案

让它发布，但我很困惑....与发布配置文件有关.如果我删除它并生成一个新的，则工作正常.一旦我使用GUI对其进行了编辑，就损坏了....再次生成它.到目前为止，似乎可以手动编辑，但需要等待TBD.不确定是否修复"无论重新启动Visual Studio，还是可以幸免.

Got it to publish but I am so confused....something to do with the publish profile. If i delete that and generate a new one, works fine. as soon as i edit it using the GUI, broken....generate it again. So far seems ok to edit it manually but TBD. not sure if the "fix" will survive restarting Visual studio or not.

编辑-从头开始，发现了区别.删除Properties/FolderProfile.pubxml中的以下行即可.

Edit - Scratch that, found the difference. Remove the following line in Properties/FolderProfile.pubxml and it's fine.

< TargetFramework> net5.0</TargetFramework>
