[.NetCore 小筆記] 虛擬主機上佈署 .net Core 3.1 出現 HTTP Error 500.35 - ASP.NET Core does not support multiple apps in the same app pool

最近測試東西有用一家 虛擬主機廠商叫做 SmarterASP，其中 "可能" 因為共用 application pool 的關係就會出現 HTTP Error 500.35 - ASP.NET Core does not support multiple apps in the same app pool

簡單的解決方法 假設你佈署兩個站台 該兩個站台都是用.net core 寫的，就會出現該錯誤，這時候我網路上找了一下簡單的說 該兩個網站都要修改 web.config，關鍵是 hostingModel="OutOfProcess"

原  web.config :

<?xml version="1.0" encoding="utf-8"?> <configuration> <location path="." inheritInChildApplications="false"> <system.webServer> <handlers> <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" /> </handlers> <aspNetCore processPath="dotnet" arguments=".\sample.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" /> </system.webServer> </location> </configuration>

修改後

<?xml version="1.0" encoding="utf-8"?> <configuration> <location path="." inheritInChildApplications="false"> <system.webServer> <handlers> <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" /> </handlers> <aspNetCore processPath="dotnet" arguments=".\sample.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="OutOfProcess" /> </system.webServer> </location> </configuration>

如果你只改了一個網站另一個沒改會出現

HTTP Error 500.34 - ASP.NET Core does not support mixing hosting models
Common solutions to this issue:

The bug existed in all possible states. Until I ran the code.
