roslyn in MVC

If you're using VS 2015 for development, ASP.NET projects now use Roslyn by default. The host I use as a test server doesn't support Roslyn / C# 6.0 yet. Though the website gets published successfully (using Web Deploy), I end up with an Internal Server Error.

According to this, roslyn support is added using a nuget package. So the first thing to do, is to remove the package. Open the Package Manager Console and type the following one line at a time: 





 Run the below step by step

uninstall-package Microsoft.CodeDom.Providers.DotNetCompilerPlatform  
uninstall-package Microsoft.Net.Compilers 
 
Now Remove this from Webconfig 
 
<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 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+" />
    </compilers>
  </system.codedom>
 
You are done :)

How to Stop Excel from giving a number in scientific notation

If you ever enter a very large number into a cell, you'll notice that Microsoft Excel displays it in scientific notation. For example, when you enter the number 1231231231234 in a cell, Excels displays 1.23123E+12. No matter how large you make the cell width, Excel still displays a number larger than 12 characters in scientific notation. To display the number in a format other than scientific notation, you need to reformat the cell(s). Here's how: We have two methods to get rid of this issue. Method 1 Concate the scientific notation with a single quote('), you will get the proper number. 1.11E+19 '11111111111111100000 But we have a issue still exists if it cross 20, here is an example. 1.11E+20 '1.11111111111111E+20 Disadvantage: So you cannot use method1 if it cross 20. Method 2 Step1:  Select the scientific notation , Go to format cell, select Text Step2:  Select the scientific notat...

The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine

This error bugged me for a whole day, I google a lotz and read many articles, but no use i was not able to fix this issue. I am using Windows 7 64bit O/S with 32bit Ms Office, i uninstalled Office completely and downloaded AccessDatabaseEngine_X64 and installed and run my application it worked smoothly. Then again i uninstalled microsoft access database engine and tried, i was getting that error message. So i concluded that i have to use Access database engine x 64 which was not installed during my ms office installation. you can download the same from the below URL. 64bit http://download.microsoft.com/download/f/d/8/fd8c20d8-e38a-48b6-8691-542403b91da1/AccessDatabaseEngine.exe 32bit http://download.microsoft.com/download/2/4/3/24375141-E08D-4803-AB0E-10F2E3A07AAA/AccessDatabaseEngine.exe But this did not resolved my problem, so i relayed on third party component(Infragistics).
