Answer 1

I upgraded the .NET framework to version 4.6 and it worked. The Roslyn packages are dependent on versions 4.5+, but it didn't work. So the upgrade made it work.

Answer 2

Error:

Compilation Error

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: The compiler failed with error code -2146232576.

Solution:

I faced with this problem after upgrade some NuGets and solved with below steps.

Step 1: Remove these NuGet packages from NuGet Package Console

PM> Uninstall-package Microsoft.CodeDom.Providers.DotNetCompilerPlatform
PM> Uninstall-package Microsoft.Net.Compilers

Step 2: Add these system.codedom lines before closing </system.data> tag in Web.config

    <system.codedom>
        <compilers>
            <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:6 /nowarn:1659;1699;1701"></compiler>
            <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:14 /nowarn:41008 /define:_MYTYPE=\&quot;Web\&quot; /optionInfer+"></compiler>
        </compilers>
    </system.codedom>

PS: After a while, we removed <system.codedom> completely, for fixed other errors.

Answer 3

I upgraded the NuGet package "Microsoft.CodeDom.Providers.DotNetCompilerPlatform" from 2.0.0 to 2.0.1 and that resolve this issue for me

Answer 4

For me, a similar issue was resolved by letting the other user of a server publish the app again. Everytime I published the app, it was depending on a temporary ASP.NET folder that did not exists for the other user. I hope this helps.

Answer 5

for me helped just remove NuGet packages above:

Microsoft.CodeDom.Providers.DotNetCompilerPlatform

Microsoft.Net.Compilers

Recompile and then add them back.

Answer 6

For me, it was because i tried to build a string for the Roles property of the attribute Authorize on my class.

[Authorize(Roles = IdentityRoles.Administrator + "," + IdentityRoles.BaseData)]

I had to build the different strings and just set one constant to Roles:

[Authorize(Roles = IdentityRoles.AutorizationStrings.AdminBaseData)]

where

IdentityRoles.AutorizationStrings.AdminBaseData = "Administrator,Base data";

Hope this helps anybody that tricks themself down this hole.
