MSB4062：无法从程序集Microsoft.ReportViewer.WebForms版本= 15.0.0.0加载“ Microsoft.Reporting.RdlCompile”任务

有几个类似的Stack Overflow帖子与此问题相似但不相同：

• TFS：无法从程序集Microsoft.ReportViewer.WebForms，版本= 11.0.0.0中加载“ Microsoft.Reporting.RdlCompile”任务
• 找不到“ RdlCompile”任务
• 程序集引用在我们的构建服务器上无法正确解析

我们拥有Microsoft RDLC报表设计器（https://marketplace.visualstudio.com/items?itemName=ProBITools.MicrosoftRdlcReportDesignerforVisualStudio-18001）并正在使用Visual Studio 2019。

尝试使用64位版本的MSBuild进行构建时，将生成一些RDLC报告，但由于以下错误而导致构建失败：

C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\MSBuild\Microsoft\VisualStudio\v16.0\ReportingServices\Microsoft.ReportingServices.targets(24,2):
