1、手动添加<ProjectGuid>

.NET Core项目()(.csproj)中没有<ProjectGuid>...</ProjectGuid>来指定默认的模板，需要手动来添加。编辑修改.csproj文件如下：

<PropertyGroup>
  <!-- other properties here -->
  <!-- SonarQube needs this -->
  <ProjectGuid>{E2CEBBAF-6DF7-41E9-815D-9AD4CF90C844}</ProjectGuid>

确保将项目正确的GUID放在<ProjectGuid>...</ProjectGuid>中

2、在PowerShell中添加

下面是在PowerShell中添加缺少的XML元素：

$paths = Get-ChildItem -include *.csproj -Recurse
foreach($pathobject in $paths) 
{
    $path = $pathobject.fullname
    $doc = New-Object System.Xml.XmlDocument
    $doc.Load($path)
    $child = $doc.CreateElement("ProjectGuid")
    $child.InnerText = "{"+[guid]::NewGuid().ToString().ToUpper()+"}"
    $node = $doc.SelectSingleNode("//Project/PropertyGroup")
    $node.AppendChild($child)
    $doc.Save($path)
}
