'Microsoft.Data.SqlClient.SNINativeMethodWrapper' 的类型初始值设定项抛出异常
The type initializer for 'Microsoft.Data.SqlClient.SNINativeMethodWrapper' threw an exception
我有 myExe472.exe 调用 myNet472 dll，调用使用 entityframeworkcore 的 mystandard2 dll（即 standard2.0）
这很好用。
然而，当我尝试在不同的 .exe（Dev Express xaf module.win 项目）中使用 myNet472 时，出现错误
System.Exception

有趣的是，当我将 mystandard2 引用添加到 xaf .win 项目时，代码运行正常。
解决方案是将对 mystandard2 库的引用也放在 xaf .win 项目中。
你所有的项目都必须包含 Microsoft.Data.SqlClient 参考资料
我仅在 运行 单元测试时收到此错误。通过从测试项目中通过 Nuget 包含外部引用来解决，即使它没有在测试项目中直接调用。
我有 myExe472.exe 调用 myNet472 dll，调用使用 entityframeworkcore 的 mystandard2 dll（即 standard2.0） 这很好用。
然而，当我尝试在不同的 .exe（Dev Express xaf module.win 项目）中使用 myNet472 时，出现错误

有趣的是，当我将 mystandard2 引用添加到 xaf .win 项目时，代码运行正常。
解决方案是将对 mystandard2 库的引用也放在 xaf .win 项目中。
你所有的项目都必须包含 Microsoft.Data.SqlClient 参考资料
我仅在 运行 单元测试时收到此错误。通过从测试项目中通过 Nuget 包含外部引用来解决，即使它没有在测试项目中直接调用。
