.NET Framework SP1

[Mr. Tomaszek]

Hi,
I've installed SP1 for .NET Framework 1.1 - after instalation, when I ran my app I get: "An unhandled exception of type 'System.NullReferenceException' occurred in Unknown Module". So, I can't see call stack because module is Unknown. What is worse, this error occurs not always, but sometimes...

There were no changes to app code - only difference is SP1 for .NET Framework.

Does someone have encountered similar problem? Please give me some advice or comment.

Thanx in advance.

I've searched the net and I have found that it is known error and SP1 for .NET Framework should fix it. Alas in my case it is the cause. After uninstalling .NET Framework and reinstaling it (without SP1) all returns to normal. So, I assume that there is a bug in SP1 for .NET Framework 1.1

I have a stranger error similar to that. I believe I have SP1.

And it claims that system.ArgumentException: Invalid parameter used

My problem is solved, but I really don't know how it was done :confused: Becaues of this error I have uninstalled .NETSP1 and continue my work without it. After number of days, I were tyring to reproduce the problem (by installing .NETSP1) but I can't. Everything works OK.

I don't thing that my project have changed so much. Maybe it is effect of some others fixes I have installed form WindowsUpdate since then.

So first update your Windows.
