T4模板当我升级到.Net 4.8时，程序集加载停止运行

如何解决T4模板当我升级到.Net 4.8时，程序集加载停止运行

我有一个T4模板，当我的项目使用.Net 4.6.2时，模板正在运行。我正在使用Visual Studio 2019。

<#@ template debug="false" hostspecific="true" language="C#" #>
<#@ assembly name="System.Core" #>
<#@ assembly name="$(SolutionDir)MyProject\bin\x64\Debug\MyProject.FooBar.dll" #>
<#@ output extension=".cs" #>
<#@ import namespace="System.Collections" #>
<#@ import namespace="System.Collections.Generic" #>
<#@ import namespace="System.IO" #>
<#@ import namespace="System.Linq" #>
<#@ import namespace="System.Reflection" #>

升级到.Net 4.8的整个解决方案后，尝试运行模板时出现以下错误。

过去，我环顾四周，发现了一些类似的问题，但是修复程序使用的是完全限定的名称（检查），或者尝试使用此修复程序T4 Template Could not load file or assembly 'System.Runtime,Version = 4.2.0.0'，但我尝试无济于事。
