Fixing SignalR Max Connection Limit Issue

SinglaR does not have any limitations of concurrent connections. We need to set the IIS aspnet.config

Please open path: %windir%\Microsoft.NET\Framework\v4.0.30319\aspnet.config and add/change the maxConcurrentRequestsPerCPU property of the pool. 

<system.web>
    <applicationPool maxConcurrentRequestsPerCPU="20000" />
</system.web>

Rebuild All Index of All Table of All Database - SQL Server

To Rebuild all Indexes of all Tables of all databases can be done using this code.

DECLARE @Database VARCHAR(255);
DECLARE @Table VARCHAR(255);

SET @fillfactor = 80;

DECLARE DatabaseCursor CURSOR FOR

             AND state_desc = 'ONLINE'
    ORDER BY 1;

OPEN DatabaseCursor;

FETCH NEXT FROM DatabaseCursor
INTO @Database;
WHILE @@FETCH_STATUS = 0
    BEGIN

        SET @cmd = 'DECLARE TableCursor CURSOR FOR SELECT ''['' + table_catalog + ''].[''

            END;

        CLOSE TableCursor;
        DEALLOCATE TableCursor;

        FETCH NEXT FROM DatabaseCursor

C# byte [ ] Array Compress and Decompress with GZipStream

A small utility class for compressing and decompressing byte [ ] array in C#

using System.IO;
using System.IO.Compression;

public static class Compression
{
    public static byte[] Compress(byte[] data)
    {
        using (var ms = new MemoryStream())
        {

            {
                gzip.Write(data, 0, data.Length);
            }
            data = ms.ToArray();
        }
        return data;
    }

    public static byte[] Decompress(byte[] data)
    {
        // the trick is to read the last 4 bytes to get the length
        // gzip appends this to the array when compressing
        var lengthBuffer = new byte[4];
        Array.Copy(data, data.Length - 4, lengthBuffer, 0, 4);
        int uncompressedSize = BitConverter.ToInt32(lengthBuffer, 0);
        var buffer = new byte[uncompressedSize];
        using (var ms = new MemoryStream(data))
        {
            using (var gzip = new GZipStream(ms, CompressionMode.Decompress))
            {
                gzip.Read(buffer, 0, uncompressedSize);
            }
        }
        return buffer;
