Server Error after installing Umbraco 8.0.0

Hello All,

I tried to install Umbraco 8.0.0 on local machine using Package Manager Console on Visual Studio 2015 and .NET Framework 4.6.1. I ran the project after build, and after that, I encountered this error.

Please help, ASAP.

Hi

Umbraco 8 requires Visual Studio 2017 (v 15.9.6 or later) and .net 4.7.2

https://our.umbraco.com/documentation/Getting-Started/Setup/Requirements/#local-development

I think the errors you are seeing relate to that.

Thanks a lot, Kevin. Sad to know that, it's incompatible with Visual Studio 2015 and .NET 4.6.1.

It would be even sadder if it was IMHO :-)

Vs2017 is being replaced by vs2019 next month, .Net Framework 4.8 will (most likely) be the last version of the .Net framework before it’s just .Net Core.

I welcome this move alot :-)

Just wanna add that you if you're facing this error even after getting all the version compatibility right, do this:

Step 1 : Go into the web.config and look for this section:

<system.codedom>
<compilers>
    <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:6 /nowarn:1659;1699;1701" />
    <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:14 /nowarn:41008 /define:_MYTYPE=\&quot;Web\&quot; /optionInfer+" />
</compilers>

Step 2 : Go into the packages.config and look for this line:

<package id="Microsoft.CodeDom.Providers.DotNetCompilerPlatform" version="2.0.1" targetFramework="net452" />

Step 3 : Update the version number in the web.config file to match the version in the line of the packages.config file.

<system.codedom>
<compilers>
    <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=2.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:6 /nowarn:1659;1699;1701" />
    <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=2.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:14 /nowarn:41008 /define:_MYTYPE=\&quot;Web\&quot; /optionInfer+" />
</compilers>

That should fix it. Failing the above you could just run this command in the Package Manager Console:

Update-Package Microsoft.CodeDom.Providers.DotNetCompilerPlatform -r
