How to get rid of “$(ReplacableToken…)” in web.config completely

You have to edit your .csproj file and in the Debug PropertyGroup you’ll have to add the following:

<AutoParameterizationWebConfigConnectionStrings>False</AutoParameterizationWebConfigConnectionStrings>

I have the following on Release and ReleaseCERT Configurations in my Project.csproj (I’ve only added the AutoParameterizationWebConfigConnectionStrings line):

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == '**Release**|AnyCPU' ">
    <DebugType>pdbonly</DebugType>
    <Optimize>true</Optimize>
    <OutputPath>bin\</OutputPath>
    <DefineConstants>TRACE</DefineConstants>
    <ErrorReport>prompt</ErrorReport>
    <WarningLevel>4</WarningLevel>
    <!-- add the following line to avoid ConnectionString tokenization -->
    <AutoParameterizationWebConfigConnectionStrings>False</AutoParameterizationWebConfigConnectionStrings>
</PropertyGroup>
<PropertyGroup Condition="'$(Configuration)|$(Platform)' == '**ReleaseCERT**|AnyCPU'">
    <OutputPath>bin\</OutputPath>
    <DefineConstants>TRACE</DefineConstants>
    <Optimize>true</Optimize>
    <DebugType>pdbonly</DebugType>
    <PlatformTarget>AnyCPU</PlatformTarget>
    <ErrorReport>prompt</ErrorReport>
    <!-- add the following line to avoid ConnectionString tokenization -->
    <AutoParameterizationWebConfigConnectionStrings>False</AutoParameterizationWebConfigConnectionStrings>
</PropertyGroup>
