我在OpenSUSE Tumbleweed上，并从这个页面安装了Blazor：
https://learn.microsoft.com/en-us/dotnet/core/install/(从这里下载了特定的tar.gz文件：https://dotnet.microsoft.com/download/dotnet-core/3.0(
现在当我运行dotnet --version时，我得到 3.0.101。
所以我添加了如下所示的 Blazor 模板：
dotnet new -i Microsoft.AspNetCore.Blazor.Templates::3.1.0-preview4.19579.2
并尝试创建这样的项目：
dotnet new blazorwasm -o BlazorDemo
cd BlazorDemo
dotnet run
但是，该项目已创建 - 运行时出现此错误：
/home/petar/.nuget/packages/microsoft.aspnetcore.blazor.build/3.1.0-preview4.19579.2/targets/Blazor.MonoRuntime.targets(151,5): error MSB4062: The "BlazorCreateRootDescriptorFile" task could not be loaded from the assembly /home/petar/.nuget/packages/microsoft.aspnetcore.blazor.build/3.1.0-preview4.19579.2/targets/../tools/netcoreapp/Microsoft.AspNetCore.Blazor.Build.Tasks.dll.

知道问题可能是什么吗？
正如 Agua 提到的 - 我使用的是 .NET 3.0。 但我使用的是 3.1 的模板。
所以 - 我删除了dotnet文件夹并再次安装了正确的版本：
- 本教程 - https://learn.microsoft.com/en-us/dotnet/core/install/sdk?pivots=os-linux
- 下载页面 - https://learn.microsoft.com/en-us/dotnet/core/install/sdk?pivots=os-linux#all-net-core-downloads
现在我可以在不受支持的 Linux 发行版上运行 Blazor:)
