Hi there!
We are sorry, but it is simply
impossible to run an application under ASP.NET 1.0 using our Cassini. UltiDev Cassini has two builds: one is for ASP.NET 1.1 (it always loads CLR 1.1 for applications that are marked as for 1.0 and 1.1 version of ASP.NET), and another one is for ASP.NET 2.0 - it loads CLR 2.0 for all applications it runs. If both UltiDev Cassini for 1.1 and for 2.0 are installed, then Cassini for 1.1 will run all applications for CLR 1.1 and earlier (including 1.0 apps), and Cassini 2.0 will run apps for ASP.NET 2.0. However,
if only Cassini for ASP.NET 2.0 is installed (or both installed but Cassini 1.1 service is not running for some reason)
all applications will be running under ASP.NET 2.0 because most ASP.NET 1.x applications are compatible with ASP.NET 2.0 runtime. So if your ASP.NET 1.x application is running under 2.0 .NET Framework for some mysterious reason, it means Cassini for 1.1 either not installed or failed to start (if it's installed and not running please check windows Event Log for error entries related to Cassini). But in any case your app will always be running either under 1.1 or 2.0 - never under 1.0.
Best regards,
UltiDev Team.
