.NET Core locking files
I have a ASP.NET Core app. I run the application by running the command
dotnet run
I'm seeing the following error in one out of five situations when I build this ASP.NET Core app.
C:...\error CS2012: Cannot open 'C:...\bin\Debug\netcoreapp1.0\AAA.Web.dll' for writing -- 'The process cannot access the file 'C:...\bin\Debug\netcoreapp1.0\AAA.Web.dll' because it is being used by another process.'
In addition to the above issue, I also see no updates that I make in the CSHTML file. I have to stop the dotnet run command, build the app again and then run the dotnet run command.
How can I fix these issues?
Solution
This may also help when running your aspnetcore app in IIS.
Add the following to your csproj:
<Target Name="PreBuild" BeforeTargets="PreBuildEvent">
<Exec Command="echo "App Offline" /a > "$(ProjectDir)app_offline.htm"" />
</Target>
<Target Name="PostBuild" AfterTargets="PostBuildEvent">
<Exec Command="del "$(ProjectDir)app_offline.htm"" />
</Target>
