无法找到元数据文件“。dll”

我在一个WPF, c# 3.0项目上工作，我得到了这个错误:

Error 1 Metadata file
'WORK=- \Tools\VersionManagementSystem\BusinessLogicLayer\bin\Debug
\BusinessLogicLayer.dll' could not be found C:\-=WORK=- \Tools
\VersionManagementSystem\VersionManagementSystem\CSC VersionManagementSystem

这是我如何引用我的usercontrols:

xmlns:vms="clr-namespace:VersionManagementSystem"
<vms:SignOffProjectListing Margin="5"/>

每次构建失败后都会发生这种情况。我能得到解决方案编译的唯一方法是注释掉所有用户控件并重新构建项目，然后取消注释用户控件，一切正常。

我已经检查了构建顺序和依赖项配置。

正如你所看到的，它似乎截断了DLL文件的绝对路径…我读到过关于长度的问题。这是一个可能的问题吗?

注释、构建和取消注释是非常烦人的，构建变得非常烦人。

The Visual Studio IDE doesn't do any building behind the scenes, the Msbuild application does. The VS IDE essentially just constructs the project file that is used by Msbuild and quite often it makes mistakes if you leave it up to the IDE to figure things out on it's own. If you are getting the Metadata file '.dll' could not be found error it is likely due to the fact that the correct/expected assemblies are not being found. So perhaps Visual Studio might be creating a project file for a 4.5 framework app, and expecting 4,5 assemblies, while you are referencing 4.0 assemblies. So look at your Visual Studio settings for incompatibilities or go into the project file yourself, and manually fix it by specifying the correct path <Reference Include="C:\\correct path to assembly\\yourAssembly.dll" />.

我也遇到了同样的问题。Visual Studio没有构建被引用的项目。

写产品说明:

右键单击解决方案并单击Properties。在左侧单击“配置”。确保选中了“Build”下无法找到的项目的复选框。如果已选中，则取消选中，单击应用并再次选中方框。 (可选)必须在解决方案属性的发布和调试模式下执行此操作。

几年后再回到这个问题，这个问题很可能与Windows的最大路径限制有关:

命名文件，路径和命名空间，最大路径长度限制
