OK, what does creating upper case and lower case letters with FirebirdClient? The sample you've attached conotains no related code.

Commented by: art (art)

This code lines (line number: 125-142) from FbTableConstrains.cs file in FirebirdClient-2.5.0-Alpha2-src.7z code source.

switch (parsed[6].ToString().ToUpper(CultureInfo.CurrentCulture))
{
case "UNIQUE":
parsed[3] = "u";
break;

case "PRIMARY KEY":
	parsed\[3\] = "p";
	break;

case "FOREIGN KEY":
	parsed\[3\] = "f";
	break;

case "CHECK":
	parsed\[3\] = "c";
	break;

}

switch (parsed[6].ToString().ToUpper(CultureInfo.CurrentCulture))
This line if used Turkish character in the string has a error. (For example "primary key" not equal "PRIMARY KEY". This action return "PRİMARY KEY".)

"PRIMARY KEY" != "PRİMARY KEY"
"PRIMARY KEY" != "PRİMARY KEY"
"PRIMARY KEY" != "PRİMARY KEY"

not I. İt's İ.

But

CultureInfo.CurrentCulture != CultureInfo.InvariantCulture
CultureInfo.CurrentCulture != CultureInfo.InvariantCulture
CultureInfo.CurrentCulture != CultureInfo.InvariantCulture

This is OK.

True code is below.

switch (parsed[6].ToString().ToUpper(CultureInfo.InvariantCulture))
{
case "UNIQUE":
parsed[3] = "u";
break;

case "PRIMARY KEY":
	parsed\[3\] = "p";
	break;

case "FOREIGN KEY":
	parsed\[3\] = "f";
	break;

case "CHECK":
	parsed\[3\] = "c";
	break;

}

CultureInfo.InvariantCulture is true in all languages.

Examples:
"is null" != "IS NULL" (equal "İS NULL")

"alter domain" != "ALTER DOMAIN" (equal "ALTER DOMAİN")

This is OK.

Edited code is attached.
Find "ToUpper", and find "ToLower", and find "CultureInfo." including lines in current project.

To DDEX is ok.

Below lines from FbDataObjectSupport.xml file.

    <\!\-\-
      <Part name="Catalog" itemName="domain\_catalog"\>
    \-\-\>
    <Part name="Catalog" itemName="domaIn\_catalog"\>

This part is very important.

I am changed <Part name="Catalog" itemName="domain_catalog">

itemName="domain_catalog"

CurrentCulture.Upper(itemName) != "DOMAIN_CATALOG" in Turkish region set.
CurrentCulture.Upper(itemName) == "DOMAİN_CATALOG" in Turkish region set.
This is false.
But converting I case in "domain_catalog" this line true Turkish region set.
CurrentCulture.Upper("domain_catalog") == "DOMAİN_CATALOG" This Line false.
CurrentCulture.Upper("domaIn_catalog") == "DOMAIN_CATALOG" This line true.

Solution:
All itemNames in this file is convert uppercase.
exam:

Original line <Part name="Catalog" itemName="domain_catalog">
Edited line <Part name="Catalog" itemName="DOMAIN_CATALOG">

This method all times true.
