这是我最近每天打开和编辑的项目
有一天，我可以在午餐前编译，构建，发布项目，
在我回来后，它的构建失败并显示错误框构建失败（有构建错误，你想继续并运行上一次成功的构建），但没有显示错误（除了一些字符串，我没有改变任何东西，它是本地项目，因此只有我可以编辑它）
有警告信息，但我不知道它是否重要
Severity Code Description Project File Line Suppression State
Warning Found conflicts between different versions of the same dependent assembly. In Visual Studio, double-click this warning (or select it and press Enter) to fix the conflicts; otherwise, add the following binding redirects to the "runtime" node in the application configuration file:
我想知道解决方案怎么能突然死掉，我怎样才能追踪和恢复这个解决方案（如上所述，我正在午餐前处理这个项目）

似乎微软已经处理了这个问题并正在修复。似乎还有一个解决方法（我还没有尝试过）https://marketplace.visualstudio.com/items?itemName=ProBITools.MicrosoftRdlcReportDesignerforVisualStudio-18001&ssr=false#review-details
同样的问题，
1>Build FAILED.
1> 0 Warning(s)
1> 0 Error(s)
所以，我在输出窗口搜索失败，然后我发现了这个
1>Task "RdlCompile"
1>Done executing task "RdlCompile" -- FAILED.
1>Done building target "RunRdlCompiler" in project "foo.vbproj" -- FAILED.
确保你有这个选项：输出verbosity =详细，
options / build和run /“MSBuild项目构建输出详细程度”=详细
