以下来自Microsoft的this tutorial,我在Powershell窗口中收到此错误

Dotnet Preview6 SDK带有Blazor服务器端模板。仅在要创建托管的客户端或库时才需要安装模板。
要安装模板,您应该使用dotnet new -i
作为模板的名称,以及(可选)版本。
添加模板后,您忘记设置模板的版本,您做了:
dotnet new -i Microsoft.AspNetCore.Blazor.Templates # Bad. Don't copy-paste
代替:
dotnet new -i Microsoft.AspNetCore.Blazor.Templates::3.0.0-preview6.19307.2
由于这个原因,您是否两次拥有blazorserverside
:每个版本一个。
好消息,很容易解决。
第1步:删除错误的模板:
dotnet new -u Microsoft.AspNetCore.Blazor.Templates
第2步:安装(可选)新的。请记住,您不需要此模板即可仅创建服务器端的blazor应用程序。
dotnet new -i Microsoft.AspNetCore.Blazor.Templates::3.0.0-preview6.19307.2
享受您的实验室。
