.netcore3.1.8部署在IIS上经常性报错(exit code 80131506)

一打开页面就报错，偶尔正常，系统日志中错误如下：

Application: w3wp.exe
CoreCLR Version: 4.700.20.41105
.NET Core Version: 3.1.8
Description: The process was terminated due to an internal error in the .NET Runtime at IP 69D00BE5 (69CA0000) with exit code 80131506.

在.netframework 下，直接修改webconfig文件即可，增加

 <runtime>
    <gcServer enabled="true"/>
    <gcConcurrent enabled="true"/>
  </runtime>
</configuration>

　但在.netcore中，修改webconfig根本没效果，只能在工程中修改，即.csproj文件，增加如下配置：

<PropertyGroup>
    <ServerGarbageCollection>false</ServerGarbageCollection>
    <ConcurrentGarbageCollection>false</ConcurrentGarbageCollection>
 </PropertyGroup>

　　搞定
