    Hi,

    Maybe you can clear the bin & obj folders , then rebuild your project.

    Hi,

    Here are my steps:

    1. Create a new project abp new QaUpgrade -t app-pro

    2. Use Suite to upgrade the project to the pre release version.

    3. Update all microsoft* packages to 5.0.0

    4. Fix some namespace issues

    5. Remove and readd migration file.

    6. run the DbMigrator application then run .web project.

    we just moved to .net 5 and ver 4.0.0 of abp. what we found when we did this was wheni run the site it works, but if i stop it and restart it from visual studio we get a context already closed exception. after a bunch of playing around and testing i find that if i clear the cookie then i can restart it because it pushed me through the login again. so what it looks like is whe i return to the browser and a session or cookie is still alive from a previous session it fails to work, but if i delete the cookie and i am forced to authenticate then it works fine. have you seen this before?

    Maybe related to your application, can you make a simple project to reproduce ? thanks.

    See https://docs.abp.io/en/abp/latest/Unit-Of-Work#conventions

    Maybe your method is not in conventions, so you need add [unitofwork] manually.
