[No relevant source lines]:Compiler Error Message: CS0433

Hi, Sorry again for a long communication gap. I was indulged into many things other than programming. Last week I came across the "Compiler Error Message: CS0433", "[No relevant source lines]". I was on vacation at my village without access to the internet when one of my friends told me about the error. I got the feel that the the specified error can be due to duplicate assemblies. I asked further about the hosting parameters and environment, he told me that initially they had precompiled deployment and now it's with the source.

If you have 2 assemblies (ddl files) within the same web application bin folder named _Default. This could happen if another ddl had a web page named default.aspx whose codebehind was compiled in that ddl but you (or someone else) replaced the default.aspx whose codebehind was in another assembly.

So the error is due to version conflict of dlls. Clean the bin folder old version of dlls.

My friend removed the bin folder and recompiled the solution and then published. The error disappeared.

Running 32 bit .net application on 64 bit operating system

IIS 6.0 supports both the 32-bit mode and the 64-bit mode. However IIS 6.0 does not support running both modes at the same time on a 64-bit version of Windows. ASP.NET 1.1 runs only in 32-bit mode. ASP.NET 2.0 runs in 32-bit mode or in 64-bit mode. Therefore, if you want to run ASP.NET 1.1 and ASP.NET 2.0 at the same time, you must run IIS in 32-bit mode.


ASP.NET 1.1, 32-bit version
To run the 32-bit version of ASP.NET 1.1, follow these steps:
1. Click Start, click Run, type cmd, and then click OK.
2. Type the following command to enable the 32-bit mode:
cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1
3. Type the following command to install the version of ASP.NET 1.1 and to install the script maps at the IIS root and under:
%SYSTEMROOT%\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe -i

ASP.NET 2.0, 32-bit version
To run the 32-bit version of ASP.NET 2.0, follow these steps:1. Click Start, click Run, type cmd, and then click OK.
2. Type the following command to enable the 32-bit mode:
cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1
3. Type the following command to install the version of ASP.NET 2.0 (32-bit) and to install the script maps at the IIS root and under:
%SYSTEMROOT%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i
4. Make sure that the status of ASP.NET version 2.0.50727 (32-bit) is set to Allowed in the Web service extension list in Internet Information Services Manager.


ASP.NET 2.0, 64-bit version
To run the 64-bit version of ASP.NET 2.0, follow these steps:1. Click Start, click Run, type cmd, and then click OK.
2. Type the following command to disable the 32-bit mode:
cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 0
3. Type the following command to install the version of ASP.NET 2.0 and to install the script maps at the IIS root and under:
%SYSTEMROOT%\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe -i
