Question

我在解决方案中添加了一个NUnit测试项目（.NETStandard，Version = v2.0）以测试blazor服务器应用（netcoreapp3.0），当我尝试添加对blazor服务器应用的引用时，出现此异常：

Error NU1201 Project {BlazorServerProjectName} is not compatible with netstandard2.0 (.NETStandard,Version=v2.0). Project {BlazorServerProjectName} supports: netcoreapp3.0 (.NETCoreApp,Version=v3.0) {DotNetStandardProjectName} {DotNetStandardProjectNameCSProjectFilePath}

似乎有可能使用Blazor创建单元测试项目，因为SteveSanderson拥有博客并且能够下载他的代码here，但是在尝试编译时遇到了以下错误-错误绕过dotnetcore3.0与dotnetstandard2.0的同一问题，我想知道我的Visual Studio是否在寻找错误的位置来编译我的解决方案？

无法将Blazor Server项目参考（.NETCoreApp，Version = v3.0）添加到.NET标准类库项目（.NETStandard，Version = v2.0）
