Hi.
After migrating my app to .NET 4 it's not starting. When i'm trying to load it in browser it endlessly loading it and nothing else happening. There is no errors or timeouts, just loading.
Please help. What should i do? What reasons there might be? I'm using IIS6 btw.
Did you register .NET 4 with IIS? Do you need to call aspnet_regiis.exe from the 4.0 directory?
Are you sure the app is using the correct Application Pool? Is the pool set to .NET 4? Is it integrated?
What does your web.config look like? Does the compilation node contain targetFramework="4.0"? Are you referencing 4.0 versions of the assemblies you need?
Unfortunately there is a ton of places to look into.
After some weird combination of IIS restarts, site stops and appPool recycles everything began to work fine.
