有几个类似的堆栈溢出帖子与此问题相似但不完全相同：
- TFS："Microsoft.Reporting.RdlCompile"任务无法从程序集加载 Microsoft.ReportViewer.WebForms， Version=11.0.0.0
- 未找到"RdlCompile"任务
- 程序集引用无法在我们的生成服务器上正确解析
我们有Microsoft RDLC报表设计器(https://marketplace.visualstudio.com/items?itemName=ProBITools.MicrosoftRdlcReportDesignerforVisualStudio-18001(，并且正在使用Visual Studio 2019。
尝试使用64 位版本的 MSBuild生成某些 RDLC 报告时，我们生成失败并显示以下错误：
