Hi there,
I have been upgrading several different VS2008 projects into VS2010 and have found a problem with VB.Net projects when they are converted.
Once converted, the .vbproj files have changed from this in VS2008:
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' ">
<DebugSymbols>true</DebugSymbols>
<DebugType>full</DebugType>
<DefineDebug>true</DefineDebug>
<DefineTrace>true</DefineTrace>
<OutputPath>bin\Debug\</OutputPath>
<DocumentationFile>CustomerManager.xml</DocumentationFile>
<WarningsAsErrors>41999,42016,42017,42018,42019,42020,42021,42022,42032,42036</WarningsAsErrors>
</PropertyGroup>
To this in VS2010:
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' ">
<DebugSymbols>true</DebugSymbols>
<DebugType>full</DebugType>
<DefineDebug>true</DefineDebug>
<DefineTrace>true</DefineTrace>
<OutputPath>bin\Debug\</OutputPath>
<DocumentationFile>CustomerManager.xml</DocumentationFile>
<NoWarn>42353,42354,42355</NoWarn>
<WarningsAsErrors>41999,42016,42017,42018,42019,42020,42021,42022,42032,42036</WarningsAsErrors>
</PropertyGroup>
The main difference, is that in the VS2010 version, the 42353,42354,42355 value has been added; Inside the IDE, this manifests itself as the following setting in the Project Properties | Compile section as:
"Function returning intrinsic value type without return value" = None
This isn't a problem when building code inside Visual Studio 2010, but when trying to build the code through our continuous integration scripts, it fails with the following errors:
[msbuild] vbc : Command line error
BC2026: warning number '42353' for the
option 'nowarn' is either not
configurable or not valid
[msbuild] vbc : Command line error
BC2026: warning number '42354' for the
option 'nowarn' is either not
configurable or not valid
[msbuild] vbc : Command line error
BC2026: warning number '42355' for the
option 'nowarn' is either not
configurable or not valid
I couldn't find anything on Google for these messages, which is strange, as I am trying to find out why this is happening.
Any suggestions as to why Visual Studio 2010's conversion wizard is doing this?
